- Full video of low power SPL testing to find peak output and efficiency and then a full power burp at peak. I wanted to do some single digit testing, but it needs to be done at a higher power level. Look for that in an upcoming video.

I was lucky enough to get a demo this weekend of this build. Absolutely amazing!!! The low end was no surprise being a 24" IB, but the mid bass range really blew my mind. I was not expecting that. Great clean install!!!
Thanks, Charles. I enjoyed the video on your home theater.
ahh now i understand why it's doing a 147.7DB@16hz IB setups to me if done right is a cheat code for ultra lows at high volumes.
I knew it would do a 140, but I thought it would do it at like 30hz AND down, not take all the way till 18hz to hit it. Anyway, this just goes to show that pressure is only half the equation (technically 1/3) when it comes to loudness. The other half is the volume of air moved. An extremely windy 140 is just as impressive as an average or light wind 150, but it's less potentially damaging to the ears and much easier on your car.
If it were me, I like to assume I'd still want that 50 though. I went to my first audio show and listened to like 6 vehicles that all hit a 50 or better and instantly fell in love. Past 155 started to hurt, though, so I'm good with just a 50.
EDIT: Oh... I suppose I sent my comment too soon. Good lord....
That was low power testing.
@@BatdogGarage Yeah, I ended up editing my comment when I saw the 147, lol.
Loudest car I ever made was a long time ago with 3 SPL160 Soundstream subs with a Reference 1000 on each one in a 240 hatch and that was 153db at the windshield at 30hz! Thats just nuts for a single sub on that low of power.
Lot of single subs doing over 150s now I have a single sub doing 147s at 2 ohms and 1300 watts but I am about to try my hand at this infinity baffle in the new car
The subwoofers and amplifiers you used to score a 153db, were probably on the much older spl meters, such as linear x, audio control, or b&k. I only mention this as a reference point, because those older spl meters, even when calibrated correctly, showed 3db to 7db higher than the spl meter used in this video=Term Lab spl meter. Again not bashing, just for a reference point. Hope this helps? Have a great day.
I still have my 2 SPL 160 15's 😎 I bought them from a school friend back in 1999 for $300 lol
@@headkase11 Awesome, alot of us would love to have kept audio gear from our past!
@@evilinside5984 I gave them new foam surrounds and played them last year. I'll probably be buried with them
Maybe make a more "clickbaity" title and video? I feel like this deserves more views fr.
Wow wow wow wow.....wow. That settles it. About to call you Nick for a pair for the house! Now I am sure I dont need that 8kw amp!
Unfortunately Nick was in an accident last night and is in the hospital. He'll be out of the office for a few days. You can still order online. No need to call.
love it man, great work
great demo showing everything
Yep ...the IB24 is a MONSTER and the output, for one driver is just insane ....Im debating on putting my second one in my F150 ...just trying to get a design imagined ...
Im still tweaking my system with new mids and highs and the MiniDSP 8x12 ...so I'll try to post a video when I get it dialed in .... working with Dirac Live Minidsp is more complex than I imagined
I do have quite a bit more power on mine than the SQ amp ....
Yeah, MiniDSP Dirac units can be a bit confusing to work with at first. How much power are you running? With this one we've got a dyno proven 875 Watts x 2 at 4 Ohms, but only saw 480 due to impedance rise.
@@BatdogGarage It's a Teramp 5K BASS model running at 2 ohm so 2.5k ...SPL on the windshield was 139 @ 55hz ..which seems to be a huge peak in my cab - sub is mounted in a blowthrough ...I just did another round of measuring this morning and its really really starting to come together with the front stage ... I had the mid bass / midrange xover too high and now that the midrange is set much lower it improved the front stage dramatically .... I found at the end of the 8x12 manual (after it explains how to setup midbass/midrange/tweeter separately in the display settings that the best Dirac tune comes from summing the drivers together is Dirac measurement instead of letting Dirac measure and correct them separately ie midbass/midrange/tweeter (3 way) gets a full sweep assigned in Dirac Calibration as Channel 1/2 - Rear midbass / tweeter (2 way) as Channel 3/4 then the Sub as channel 5.... I did also set the rear channels as suggested (L-R / R-L in the matrix and 20ms delay) haven't really tested enough to hear that rear delay but the front stage is really sounding great and very balanced with the sub (which is also inverted) ...and FYI the sub is taking every bit of the 2.5k without even breaking a sweat ..
@@rts100x5 I had a Dayton Audio Kraken off a Smart 3k at 4 ohms, so 2000 watts and did a 139.4 in a blow through in my 2011 GMC Sierra. I have 2 Dayton Audio Ultimax 18's off a JP 23v2 at 2 ohmsand they are much louder now. I am going to 2 Resilient Sounds 18's each off a JP23v2 at 1 ohm for 6600 total watts.
even my old Subaru Legacy wagon back in the day (2001) had 4 Rockford 15s on a Audiobahn 2.3k and it was doing 152 on the windshield with stock alternator no less + 3 yellow tops .... the enclosre was basically from the back of the front seat to the hatch ... even as loud as it was I wouldn't trade it for 1 minute against my IB24 which plays much lower and is still plenty loud ....
Ib24 sealed or ported?
Best video I seen in a long time.
Probably need some type of dues fastener on hatch to pull it to and hold it. Those are fasteners used commonly on race car panels
I thought a 140 at 20. U did that while finding the peak. Wow. Thats an easy 150 on windshield door open. At that wattage. Thats impressive!
It's IB, so door open would probably hurt the equipment
@@poboy8490 You must not have watched this whole video? All test scores in this video, were done with passenger side window down, and spl meter on the drivers seat, @ ear level.
@@poboy8490I did an IB and I could open doors and roll down windows even open the trunk full volume and it did affect a thing so probably not. Haha.
heeey so glad i found you!
Thanks, man.
@@BatdogGarage if u had some time i'd like to ask someone knowledgeable like you. Thing is, we can't tear the car's frame here in Spain for IB. I have a third gen audi a3 hatchback and was thinking about installing 2 IS HT18's sealed on an 8cu.ft enclosure (willing to sacrifice whole boot). I'm looking for LFE and SQ from 25-80hz. Question here: Would you recommend another better driver for this car, knowing what i'm looking for?
Wow I need something like this 💪
I told Nikhil to reach out to you about the demo since i dont have a fb. The 140@17 is funny because thats our aim for his car
And it did that 140@17 in low power testing.
@@BatdogGarage im aware, i just told nikki (the name he goes by to non-indians, lol) about the 147@16
Were doing 2 sql-15s ported @17hz on a salt 6 in a vw rabbit, box size undetermined yet, once the subs are in well see what fits where
The headrest number is far more impressive than glass and kick
just curious, what is the diameter of the ib hole that vents outside? 18in?
That's amazing! How do you get so much volume out of so little power?
Impedance rise
How is such a high SPL score possible with this little wattage? It feels like you could power that thing with the stock amplifier?
Large sub helps.
It's IB so it takes wayyyy less power to get to LXMAX as there is no box acting as a spring, causing resistance to the cone.
Also it have 80mm of XMAX @70% BL so this thing will move tremendous amounts of air.
That's crazy. Nice build
This was beautiful my friend I want to now cut out my trunk floor too 🥲
What kind of alternator are u running
JS Alternators 390
Fuckinv amazing I have a single sundown u 15 I had in a big box in a Tahoe o sold my taboe and got a Chrysler 300 and you sir have mad me be the first out of my group to do this infinity baffle in the new build wish me luck I have a sundown 15 on a jp23 at 2 ohms clapped in the Tahoe it did 147.6 at 1300 watts with a big alt and battery’s so got to get battery’s in this and not sure if I am gonna build it like your where the motor is under the car or do like a wall at the back seat into the trunk
If you were my teenage neighbor i would hate this but as long as your not driving around pissing people off its awesome.
I live on property out in the country.
@@BatdogGarage lucky man
What is the bass like outside the car when sealed up since it is baffled to the outside of the car? Does every hear the bass as much as you do. Like if you. Were sitting at a light next to a cop would they bust you because it would be 140db plus?
No. With the windows closed there’s very little sound outside the car. You’re sitting in the enclosure. When you open a window it essentially becomes a ported/vented enclosure and it’s allowed to breathe and get windy. That’s when people hear it.
@@BatdogGarage Ahh, thank you. I have never heard an IB to the outside and it is just such an awesome idea and space saver.
So it looks like it plays up to around 50Hz and then the output starts to drop off rather dramatically.
I get the same thing in my full size suv. The output starts to roll off above 45Hz.
Is this due to some type of 1/4 wave cancelation?
I assume that 24" sub can play those upper frequencies fine and my subs certainly can as well. Its strange.
What are you using to play the upper bass range? (60Hz to 80Hz) Front mounted sub/mid bass driver?
I still had a crossover on.
@@BatdogGarageSo, have you ever used an rta to see how they perform?
Can it play 60hz if the crossover was raised?
Came from Reels, was not disappointed!
It didn't show the vibrations but the audio was absolutely swamped if you talked during a test! Wild numbers for that low of power!
Yeah, I noticed that as well. Mic was attached under the collar of my shirt.
IB at its best
I'll guess around 20-25 hz and about 300 watts..
Deleted my other comment and couldn't reply back. This is almost weirdly-efficient. I'm not an expert but I have done builds myself year ago. Is this having something to do with the cone using the ground as a backplate? Or maybe it's just this woofers design? Seems wild that it's putting out those number at that hz with such low power.
It’s largely due to cone area and efficiency. The sub has a Qts of .7 which means it doesn’t require an air spring/enclosure. It’s designed to operate as you see it with simply front wave/back wave isolation.
It IS wild. Getting in a complete stealth build with a 24 that’ll get windy blows people away. It will be at the Sundown Show tomorrow.
I realize this is infinite baffle. What size box do you have? I m putting two 12 inch infinitys in my van.
There is no box.
Very cool but what kind of music plays that low 😂. I feel like 30-60 is where you want the most db's..impressive on such low wattage while retaining all that trunk space though!
Bass I Love You has 8hz in it. Pipe organs at 16hz are common.
This is crazy
epic
Where is the fuel tank?
Stock location. Under the rear seat.
Really cool 😎 😝🥴
Full send... 150 was my guess
147.5 to 150 is a huuuuge gap. Huge gap
What does it do sealed?
found it >>> th-cam.com/video/76c7IrwddsM/w-d-xo.html
Insanity :D
Why do you test at such high frequencies?
Just covering the entire frequency range the sub is playing.
Did you also see later in this video, they tested infrasonic freq., down to 10Hz?
Ha! I actually guessed 17hz
*golf clap*
My bet is 16hz maximum output
I’m going to use second skin on my work truck 🛻
I’m in that thing all the time and I want to give it the treatment 😝👌
