The thing that was more common back during the 80's and 90's was multiple large, high sensitivity (90db+) subs in huge sealed boxes. Not too many bass heads ran single subs back in the day. Giant boxes in minitruck beds and hatchbacks, high sensitivity and massive amounts of cone area. A Punch 150 bridged to 2.66 ohms on six 150w 12's in a box that took up most of a truck bed was common for the day, and would get quite loud. Also Orion XTR dvc subs were rated @ 800w rms and were pretty common. As far as getting your spl measured, local stereo shops usually had an spl meter and would come out and measure it for you if you asked. Having said all that, the modern stuff is better in almost every way, except arguably SQ, and it's definitely a whole lot more affordable.
@Willie, the Punch 150 was a powerful amp for its day. I actually did a 150 sealed with one. I have the video on my channel.
@@mattstarke7373 Yes it was. In 1993, one of my buddies bought an S10 Blazer demo vehicle from one of our local shops. It had a wall with ten of the old school white logo Punch 18’s in it. Originally, the shop was running them off a Power 1000, but when they sold it to my buddy, they pulled the big amp out and replaced it with one of the new (for the time) Punch 200m’s. Those ten sealed 18’s barely moved, and I could still barely sit in it because it was so loud. I’ve recently had 2 Skar EVL 12’s in the factory ported Skar box in my 2 dr hatchback Focus running off a Skar RP2000.1D, and it couldn’t touch the violent pressure of those ten underpowered 18’s.
Sir, thank you for this insight in the old days. That was really interesting to read as a basshead in his mid 20s.
I'm also baked as shit right now 🤙🏼
@@NuriBass69 Reminiscing the good old days! I started in 1985 when Kenwood first came out with a indash CD player, it didn't even have a FM receiver, just CD. I built a box in the back of my van between the wheelwells, doubled as a bed. Stuffed it with four Pile 10" woofers and powered them with a old PPI 400 watt amp. The front stage I bought a Boston Scientific three way component set powered by a Rockford Punch PR-2100 4 channel 50 watts per channel. At a competition they were using a Audio Control power meter, I hit 138db. Both amps were purchased as is. Both of them needed output transistors and I repaired both of them.
@@BobBasshead Damn 138dB was good back then! Crazy how much the equipment and the numbers have changed over the last few decades. And it's still long ways ahead!
I think the meters read pretty high.
I had a Ford Escort with two MTX 3000 15s and an MTX thunder 1500dx.
The amp had a birth certificate of 775 watts.
It did 145 db with old school meters.
I doubt I could do the same number with today's meters.
The difference is in the meters. I did a 153.2db outlaw ( meter in the passenger floor board) on a audioControl meter at a car show. The Same car, same everything did a 141db on the windshield with a Termlab.
I run a mobile SPL metering company. When you put the meter down on the floorboard you will always get a higher SPL measurement then you will on the windshield. So if you go to another show and they give you the option always select the floorboard
Kinda like drag racing. It's easy to get into the high 11 second 1/4's then gaining every tenth gets harder and harder and the power needs to get much higher
That's always been my analogy too.
Why use a sub with such low sensitivity? Old school subs had a much higher sensitivity so this isn't even accurate. No one was doing 150 on one sub but the sensitivity numbers were much higher
I grew up in the 90s. The kicker demo van with 4 18s and a bunch of power for back then did mid 140s. It seemed loud. The power supply van with the 6 sealed 18s was around 150db. Those were some of the loudest. There were a few SPL vans doing 155s. That was the best of the best. Maybe 3-4 vans nationwide. I did what this kicker did with 2 8w6s and 400w in a small hb, and I was common. We all built the same boxes that people are building today, but probably more small round ports. I’m old now and went to Slamology this year and stuff is way louder. The music is different, and you have a lot more bass music to chose from, but it’s overall louder today. You can get a lot more out of fewer speakers because people are sending 10x the power to them and it’s cheap power.
Older Subwoofers: Generally had higher SPL efficiency ratings, often in the range of 86 dB to 91 dB, as they were designed to produce more sound with less power.
Modern Subwoofers: Tend to have slightly lower SPL efficiency ratings, often in the range of 83 dB to 89 dB, due to a shift in design focus towards greater power handling, deeper bass response, and more linearity, which can result in slightly lower efficiency.
@@alvinmason758 in 1992 I had two Lanzar 15’s with a 99db sensitivity rating. The 18’s were 101db. (If memory serves correctly)
The way DB was measured years ago is different to today. I know plenty of people that were doing 150 plus back then. By today's measurements that would be about 142. Plus subs had much higher sensitivity.
In the 90s and the early 2000s. The mics are about 7-8 db louder than what we are using now. 136 could have been close to a 143 in 99
As many have already said. #1 The mics read higher back then. #2 the subs had extremely loose suspensions. That was because of the low power available at the time. This also caused them to want huge (5cf+) boxes to really move or even IB. That is why they had sensitivity ratings in the mid 90s and up. It took very little power to move them and why they had "small" compared to today magnets. While you could burn up a coil then you were much more likely to bottom out the VC or tear the spider when pushing it.
My very first competition was around 1995. I had a RF Punch 200 pushing 3 Sound Stream 10’s in a ported enclosure in a Mitsubishi eclipse hatchback. It did 143 db. At that time they did it by watt class and not cone area. That’s when people used cheater amps to get into lower classes and win
Those 90's hatchback were perfect. I had a Daytona turbo z slam full..lol..
I have trophies from the 90s proving I did good numbers with less power and with a great built box it matters! You’re missing the point. No offense

Guy at my highschool, back in 1991, had a blazer, with two 18's in a huge sealed box! I didn't know what db he was hitting, but man that things was loud! Lots of pressure, could hear him coming from far away, and the school windows would jump, when he drove past the school. I can't explain it, but those systems were loud! This guy at my college, had the popular, covered truck, with eight 15's.... Mind blowing, for back then!
I had six 12" subs in the trunk of a 2 door Ford Tempo not 1 15" in a sad looking box with a ton of cargo and cabin area! When I went off to college I sold all my gear and bought a used 4Runner and had a single 12" in my 4Runner with all of the factory and option locations upgraded, new door cards to hold deep heavy 6.5" spearers. That just sounded like a really nice home theater or home hifi. My Ford Tempo with 6x 12" woofers would pop the glass out of the car I had to reenforce it. I think you have a warped sense of what people where doing in the 1990's and what was available.
Kenwood did a DB drag back in 2002, I had 2 eclipse 86000 12s in a sealed box, on 2 channels bridged from an autotek stealth series 600.s that got me to a 143.9. I showed up last minute, was hungover, never had anything metered prior to that, had a buddy tune it in the parking lot to what we thought sounded good, used a bass mechanic cd and just sent it. I only lost because they placed my microphone wrong and I was too hungover to notice and they wouldn’t let me re-run. I went and got kfc after that to kill the hangover. Great memories I tell ya!!! And yes, the RTA printout is still somewhere in my storage.
Check out the old Atomic xx94, xx99 subwoofers or Thilos stuff. More efficient drivers with less power.
I was trying to explain to my older brother how much crazier the new stuff is.. as kids we dabbled in car audio and had all the old stuff.. now im 40 and i bought a Honda CRX just to stuff a dd18 in it. Mbe did the box.. i was trying to explain to him he hasnt heard anything like this, and he kept bringing up our old systems.. stuff we had . But the minute i turned it on he was like DANG!!! Thats next level !!! 😂.. i said i told you bro . Idc who you are or what you had, its just no competition honestly.. you may be remembering loudness bc of the actual vehicles like the crx and asto which are acoustically gifted . But put that same sub in the same car.. and you will see the new stuff is just way louder, way more power..
We had class a/b back in the day. 300 watts of a/b sounds so much better than 600 watts of class d. Plus, we used oversized enclosures. You get an additional 3db for each additional sub. No one had 1 sub back in the 90s
I used to compete in sound quality comps in the late 90s... I had 2x pioneer 10s in a sealed enclosure running off a Phoenix gold M50 amp and it always tested in the 136db range. I know there were generally 2 different brands of RTA meters back then and one of them always read higher than the other.
There was an spl meter back then made by audiocontrol and it worked well .
Yeah they had ample instrumentation in the old 80s iasca competitions.
If you got a 150 on a audio control meter that's about a 142-144 on a modern meter. The audio control meter was a good meter for its time but there not what's used or even accepted in competition any more due to the difference in readings
@@paulgood2218 agreed but the numbers weren't that far off lol 2-5db is closer
@@boominc0420 I remember 6 db average
@@boominc0420 but ya I can see 2 12s or 15s or 4 12s on a 1000-1500 watts doing 142 -144 easy which would of been 150 back then. So I say that claim by old timers like my self half true. Even though I would never say it was true because I understand the difference between times
LOL. You're going to upset all the people who have been holding onto their old system memories for the past 30 years.
A couple of other points to add. Head units were different- Bluetooth didnt exist, we ran either a cassette tape player or CD player of very high quality! I also used many outboard electronic crossover networks, because my amps were stereo/mono bridgeable with little to no built in crossovers like todays amps almost all come standard - trust me active devices made a huge difference! We also spent big money on patch cables & accessories unlike i see many doing today- so i ran esoteric audio by streetwires that were $100 per 20 ft times 3 or 4 runs usually to the trunk, thats not including all the shorty patches 3ft, 6 ft 12 ft etc from electronic xovers to amps inputs or the daisy chain connections needed. $1000 on just cables alone was a big deal and you were judged on quality of accessories. Power wire was only OFC, we didn't have CCA anything for wire! My rcas weighed almost as much as 4 awg OFC and were all copper with turbine split tips. As many others have said ...drivers efficiency was higher also and more... meant louder! Vehicles were also different than todays! Less electronics then meant more space for us to fill up without the dangers of screwing up a can bus network or computer in the way, also vehicle stock wiring was stronger and thicker so conductivity was more true. Body panels werent thin and glued on so better grounds were more common! Head units of great quality had way better built power supplies in them and sound transfer through amp inputs were stronger voltages and high level inputs wasnt really a thing to worry about like today! Ive been doing this since 1986+- and owned some great equipment- I started with Carver and JBL(The real Grand Touring) look up JBL T180's i had 2 of them quad ported in an 89 Mustang LX and lots of mids and highs. Later i got into ADCOM GFA car Amplifiers-with XLR connectors inputs they were cool and different, because you had to solder your own pins depending on configuration in your build. I also jumped into Fosgate later on with the Punch 45/75/150's and then upgraded to the DSM's when they came out on the market 40/60/100/200 and IX(crossover cards in the bottom) version too later on.
Ive had & have Alpine, Sony, Soundstream old & new, ADS, i was an old school ORION dealer, phoenix gold Titanium's, PPI (Precision Power)when they were real, i sold KICKER equipment when the L7 first emerged, so many other brands ive used or installed for clients over 30+ years and never cared about DB numbers...why? because the customers & thier friends would tell you how loud your shit was and meters were just for bragging rights! I used to have people call me on my car phone and they new when my vehicle was coming towards them or thier house because I was shaking the ground they stood or lived on, miles away from me. They were very accurate pinpointing where i was😂 cops werent fans when i was near & many said they thought a UFO or 😂hovercraft was around because of my (2)18" of Techmaster P.E.B. (Bass Computer)of bass or DJ Magic Mike(Feel the Bass)& MC Madness- every car audio shop I went around were either irritated because I wasnt buying from them or I was attracting thier customers out to my ride and believe me i didn't need any SPL meter to score what i had built ;)
In a small hatchback guessing 140db or so...
143.6 in an Integra, with 1 15" Phoenix Gold X max is the only time I've seen anything close to what this video is trying to do. And 143 really isn't close
@@tomturbo1317 I had a dodge Daytona hatchback back in the day. It actually made your vision go blurry. Couldn't read a stop sign. But I had a bit of juice and 4 amplifiers. The distribution block got hot and melted the plastic on the outside..... it was 0 Guage
One guy with a civic hatchback had a cv stroker 18 in a scoop he hit 171 with a 1500 watt kicker amp..
The next guy with 6 tree 15's in an ASTRO van hit 178. Plastic cones have too many cone modes. If you build systems based on the loudspeaker cookbook the systems these days wouldn't sound like crap because everyone just slaps any subwoofer in a box without crunching numbers then they wonder why it sounds like crap.
I currently have a dd9518 sc in a Honda CRX.. I haven't meter it but it's crazy loud on 2k/2.5k .. like the guy here said it blurs your vision
I had similar setup single 15 and amp. But in much smaller vehicle and was between 143-145. It was a trunk build with rear seat down. Also metered by a shop in that time
What would be a cool test is to see what 3 cheap subs do compared to 1 paycheck sub
A better test would be using something like a pair of impp 12s or old kicker solos in a huge sealed box, just like it was done. I had impp 12s in a sealed box as big as could fit the trunk, on a punch 100. It's not nearly as loud as new era equipment I use but for 100 watts it did great! Sounded clean and played low. I will say a person doesn't understand speakers if they think they haven't improved. And you can still get stuff that works efficiently and doesn't need a huge amplifier.
Box tuning could be higher. Higher sensitivity subs back in the 90s. I do proaudio also and while a 15inch proaudio sub won't hit 35hz the way car audio sub does, at 50hz way loud with a fraction of the power. Sensitivity 97db , cabinet tuned to 42hz. Do the math.
First of all I was in car audio in Georgia and FLorida in the early 1990's. You could go into any car audio store and a lot of pawn shops and get HiFonics, Lanzar, Pheneoix Gold, JL Audio, Precission Power, Rockford Fosgate, US Amps, Kenwood, Sony, Sheerwood, JVC back when all of those brands where great high quality brands and most where made in Japan, Korea and the USA. You just had to live some place that was not John Deere friendly to have easy access to the good stuff.
SPL/db meters where a dime a dozen depending on what functions you wanted in the meter. You could buy a decent meter at Radio Shack.
the people making those claims must live in an alternate reality where perceived increases in SPL are not logarithmic requiring exponential increases in power to double perceived increases in SPL. i.e. 10x power increase to obtain 2x perceived SPL's
Cabin space makes a difference also
No, No, No. In the early 2000's we had DB Drag Raceing. I worked at a shop in 2001-03. I had two Rockford fosgate hx2 15's. When I metered, I had a a Autotek Stealth 900 but was 1500 watts. And I hit a 149.9db. And I got beat by my buddy at another shop with a 150db. We even had the Official Autotek show van. But we used to have DB Drag a lot where I was at. That's how we knew kinda what everybody was hitting.
THE METER USED ON THE TERMLAB WAS DIFFERENT AND HAS A SIGNIFICANT DIFFERENCE IN HOW IT WORKS. ALSO ANYTHING METER WITH THE NEW
MEASURING "MICROPHONES " ITS USUALLY 10DB + LESS
So another thing is this. I ran the Kicker XS100 amps. It did 100 watts @ 4 ohms. But bridged down to 0.5 ohms it did 1500 watts. I ran 3 of those amps on six 10s and was doing 153s on TernLab in the early 2000s. The difference now is that you dont have cheater amps like back then cause most organizations eitber dont have power classes or they clamp for true power.
I did a 146 with a single JL 13w3 in a 2.25 fiberglass homemade tube tuned to 27hz with a JL XD 600.1...
In a Ram Crew Cab.
thanks for the demo, i started in 95 with 2 punch 8 ohm 12's blah blah 4 ohm bridged on a ppi A600.2 in a custom bandpass box three 2 cube chambers in a crx. i'm telling you a 15 ported is not the same my guy. i guarantee it was well into the 140's and hit LOW. but people also thought a old gto was fast but today a civic si will smoke that muscle car. i guess it's all relative.
Two rockford punch 15s in a large sealed box on about 400 watts in my dodge k series station wagon and based off what i remember that felt like and the amount of flex comparing to stuff i have heard and have now and what that meters i guarantee that old school setup was pushing over 146db
🔴good try but not an accurate representation. subs back then had much higher sensitivity which would allow them to get much louder on less power
In a early 90s Ford Taurus wagon competing in the 500 watt and under a young guy with a single 15 cerwin Vega ( was not from their normal line , it was way heavier than the normal 15 and was right about the time I had first heard of the stroker but it wasn't one although the motor assembly and basket were very similar to the stroker. ) I can't remember the amp but I do remember several months of trial and error tuning and returning and I'm pretty sure he got 143.1 and that was extremely impressive fire a single sub back then ..... 1997 I think it was. And the guys claiming those big numbers probably did get them but there is a problem that answers how they did it. There wasn't a standardised way of how where and with what to take these tests . I remember a guy with a convertible that has a box in the back seat that was a huge "X" that stuck up at least 3 ' over his head. It was 4 12" one in each leg of the X firing to the middle where there was a 10 " circle cut out. So basically it was 4 band pass and the vented ends joined together in the middle forming the X. The rules for the competition for that upcoming event allowed the microphone for the meter to be basically at your port if you wanted . They were cheap ass 12" and the sound out of the box was shit but it did hit high numbers. Back then I remember fights breaking out because a guy would hit 145-146 at one event and the next one ( put on by different people and sponsors they got 132. There for a while it was literally different rules at each sound off. That is where those numbers came from and they did get them but because of discrepancies in test procedures and a verity of meters being used and on top of that calibration of test equipment was often neglected a lot.
We went to local competitions and it's very true The numbers haven't gone up that much compared to the amount of power you guys have these days and the subwoofers that you have these days,, I've seen an eclipse titanium 10 on two yellow tops in a Rockford DB1000 do a 1478 I was doing a 147.7 with 8 12 in RFZ's on two PPI art series 2150s
Inaccuracies in this video. Use a 1998 cv stroker or jbl. Sensitivities at or about 100db per sub.
I own and run a mobile SPL metering company. The bigger the vehicle you have the more power you have to put into it to get a higher SPL measurement. If you take a stereo system and put it into a small Honda Civic hatchback you will get a higher SPL measurement then you would if you take that exact same stereo system and put it into a SUV you will get a lower measurement with the exact same setup. The smaller the vehicle is the less space you have to pressurize
how does wavelength affect vehicle to vehicle differences and come into play? definitely curious
Look up look up Hoffmann iron law. Box design does indeed matter, and can easily affect the sensitivity of the sub by 6-12 DB.
Not making any hyperbolic claims, but you would probably shit yourself at the amount of output you could get from 2 15W1’s sealed on a Punch 40 back in ‘95.
I still run stuff from 2004 3hp 3hp neos and then 2005 shocker signature series. Also have some 4hp motors and tons of variations of the tc9 they can all hang with anything out there today imho.
back in the 90's i never saw a ported box either.
Either way 136db is a good amount of bass when actually just listening to music and that’s what most cars are setup for….. Not for competing, a lot of variables come into play with overall SPL…… great video though, It’s nice seeing real world examples of what anyone can achieve with just a basic setup
Nice try, but there's not even close to the stuff that was made back in the days.
Still, we had a Renault Twingo (very small car) with a wall containing 8 12's and 3 15's , 8 x 800 watts amplifiers and we could barely brake 154, it wasn't easy with the available stuff but we did allot of R&D to be competitive.
I remember people saying that😂they have no idea how loud 150db is😂
I used 2 kicker 2 channel 800 watt amps and a pair of 1000 watt RMS dual 2 ohm MA audio 15 inch subs. Nice Alpine Head unit. I had an optima redtop under the hood and 2 xs power cells in the back, big 3 upgrade but factory alt. If i did a full precharge on my cells they held decent for a while. I got a 150.3 out of that in my 89 bronco 2 build. The box was 3.25 cubic feet per sub tuned at 34 hertz. It was loud and I was happy. This was in 2002 and that was loud for around my area. Still remember when Bone Crusher with Grippin the Grain came out. The best score came from ying yang twins Alley Album the song was drop like this 2001
in early 90s friend had 2x 15 pyles in biig box with dules 4 inch telescope port box I think was with ice 2x100 or 150watt rms in 2ohm went to db comp 150db...I have been trying to find specs on those subs but cant find it .
The old meters they ran back then did not read like the ones today 150 back then on the old meters in the 90s early 2000s was like a 142 on today's meters
They weren't that different from today's meters. It's more like 146/147 on today's meters.
Love my 2 comp Cs got em for lik 90 bucks could not pass it up built my first custom box for them compared to their prefab it was a night and day difference they get down and dirty with the 10zx500 not even fully powering
Box specs 24x13x17 32hz peak 62
Air velocity 20.1
Port vented
I got my drivers licenses in 89 a jumped straight into car audio. Our car shows and stereo shows all had db meter. My standard cab S-10 hit 148.8 I thought it was great!
We also metered with music!
It was also Earthquake 2-10s 2-12s and 1000 watts
What most of you guys forget to mention was,, FLASH DANCE!!!!!... we did not get to play a PURE TONE at the meter... We had to play FLASH DANCE!! MUSIC!!! not a big burp.. If you can say you was in the 150s in the late 80s through the late 90s you had a least 16 15inch subs or more..
It be interesting to see what a kick comp still water design free air sub would put out versus the new style kicker subs. I actually no to brothers that both have similar systems set ups with kicker and the older kicker set up out of the two does sound a little deeper with less effort then the older brothers new kicker set up there also both in trucks . They also argued for a hour about how's was loader in front of my house no joke 🤕 🤭💯💪✌️👍
Last comment, I promise..since we are going back to the good old days.. you all remember the guy who had the black grand national that was winning almost every sq comp.. can't reme.ber ol boys name though
Richard Clark was his name, I do believe.
@@shelvingarrett121 No, I think that was Mark F wasn't it?
@@bassntruckHe's correct. It was Richard Clark. Mark Fukuda had that sick yellow Chevy Blazer loaded with 16 Rockford Fosgate 15's, powering every 4 subs with a RF Power 1000 amp.
@@blazed_existence3338 You may be correct, It has been a long while.
MR. RICHARD CLARK.... HE HAD/HAS A SCHOOL IN NORTH CAROLINA.... AND HE HAD/HAS TGE BUICK GRAND NATIONAL, BECAUSE HE WAS/IS AN ENGINEER.... AND HE TOUTED THE GRAND NATIONAL'S MOTOR........ LOLLLLLLLL
I was running 4 15 Cobalts and a audiopipe 1500d back in 09 doing 154 in a wall and i changed the port and it got louder but i never metered it again
Greatly depends on the install, enclosure and vehicle. I probably should add frequency to the list.. But of course no one will ever hit 150 with a prefab enclosure unless they have 5,000 watts on tap.
Great video
Would love to see you try it in a 5cf box tuned to 40Hz. Enclosure sizes, as well as port tuning have gone down over the years. Back in the day 40Hz was like the standard for port tuning. If I remember correctly, it was said that 40Hz is the lowest note on a Bass Guitar, and that's why you never needed to tune lower than that.
I had a RF Punch 150 on 2 RF Audiophile 12s in 1994. Not more than 300 watts Im sure. They got down, but not in the same league as what im running now. 7000w Surge amp on 2 DS18 2k watt rms subs. My 1994 ppi 4channel at 50w per channel amp was loud, but nothing like my 250w per channel wolfram amp currently using.
different style microphone than the old AudioControl mics they used. ratings are very different.
they were also using DB meters rather than SPL meters. thats 10 db right there. lol
What are the box specs?
Is the box tune at 30Hz....???
Well... this test is bs. Why?
20years ago we didn't have so much power. Amp with 1000W was amazig. And the speakers with more than 500W were not cheap and avaible.
What we do was making the Best box possible for that specified speaker, placed in specified car. One note Wonder box or wide frequency for sq...
Your box is like SUV's of this time. Suiteble for everything so... good in nothing (as we say in poland).
And okok hitting 150dB was unicorn, but hitting high score was so rewarding man...!
And to be honest sq of todays beefy subs is poor, just listen to oldies hits and try to get the base out of them!
Today you play "bass I love you" in the matter of seconds and your whole car is schredding.
[Sorry for my English]
Remember how Punch 45 was considered a "cheater amp"
And what would it really put out❓maybe 120 watts RMS❓
And that was considered high power and high end
Y didn't you move the box around
You had to find the low .qtc value high sensitivity and know how to build an enclosure.
This looks weak right off. 150 seems laughably high tho.
You can't backproof the cheap thumper diminishing returns test.
One mtx 7500 and an autotek mean machine in a 4.5 cuft box hit 149 on a audio control meter in early 2000s
technology sucked ass back in the day that's why they had high sensitivity subs but low wattage. Plus, there truly were no high wattage amps...again technology wasn't all that. Like everything else, technology has advanced and now they can make high spl subs with high wattage amps. I'm 53 and I love today's car audio much more than back then. Think about it, besides the watt per dollar being so much better today, you can now bass with one 12" medium box and decent sub and get plenty loud. Back then, to get the same loudness you needed two 12's and one huge ass box that took up all your trunk and the costs of this type of setup was ridiculous.
Should of done a comparison with a 2000w sub with custom box
I just hit a 144.2 with a resilient sounds gold 15 d2 v1 on a surge audio pl 3k
That’s a great setup. I own both as well. Love the gold v2’s.
I had a pair of jl audio 12w0 on a sony xm1002 amp doing 142.2 back in the late 90s . But that was on the audiocontrol spl meter. And those numbers you did are limited due to tune . You could tune the enclosure to 49hz and burp it higher and you will get closer to 145.
Not a knock on your vid and love the content bud .
I gotcha. But so I could compare to my other tests I did it in same box and frequency so I have something to compare by. If they were different tuned I could not use all my other tests for reference. Thanks man for watching I appreciate it!
You shout redo this with old school w6 or stroker
I just want my sound to be heard from few blocks away I still don't know the formula
Nice 1
Altec lansing+ MTX
yeah but what does it do in a small hatchback? Tiny cars with lots of subs will do bigger numbers. Never hit 150 in that jeep on one sub.
💯💯💯...
Put Two 15” on an old school cheater amp (like punch 200 @.5 ohm it might!
Back in the day..lol I had a Daytona turbo z..Hatch back and I had 2 crunch 15's and 2 crunch 18's..I went through many amps then through a crunch 50 x 2 amp on there and my God it was louder than all other amps.. it's a shame crunch is so bAd now.. I could flip coins several inches high on the roof.. ne er heard of soundeadening back then ..lol ahhhh to be a carefree dumb kid again..lol
LOL the only way that's possible is as a siren. The truth is ,their ears were still fresh. At the time it sounded louder cuz they have not lost their hearing yet.
Hands down, there's more misinformation, made-up BS and straight up lies in this hobby than any other I'm familiar with.
I was there in the 90's and was fortunate to get demos in alot of really loud vehicles, but it sounds like false memories or bench racing to me, scoring 150dB with low power and subs with 5mm X-max.
So doing an experiment that deals with old equipment and you're using new shit that's over rated compared to old stuff? 😂
Longmill sumo subs were twice that crappy kicker also ppl injected cones were all that was available you got a lot more sound for your watts also what about hifonics orion and kole audio I don't think you realise what a set of applies bumper subs could do cripes I had 25x 10 inch 50 p subs in a ford escorting van was only running 2000w herd from a mile away I believe it's all in the tuning of the box and how creative you can be with your design be fairer we could make those figures we just blew a lot more subs doing it
Bumper! Yes! They just seem to have disappeared. I still wish I had kept mine. Great sounding and beefy for the time.
Could be how they metered could be that old subwoofers had different sensitivities could be vehicle could be a lot of variables how extreme was the vehicle that how’s the subwoofer there’s way too many variables you can take cheap subwoofers and put them in an SPL build and they would surprise you i wouldn’t say myth busted on this I’d say inconclusive.
