Maybe we're all just nerds here but this series is so much fun. Sam's choice of tests, music, gear, presentation style are all great. Looking forward to the next
This series is awesome! Such a cool idea
I agree this is the best series and completely one of a kind, he does a great job and alot of work for us viewers
Seeing this video series makes me want to build a little bluetooth box for work, something light that can efficiently move air
@@richbrown5852 do it
Nerds start as rebels...then they end up on the moon.
This series has been so much fun to watch
This series is awesome!
I hope we get to see a Transmission Line and a Infinite Baffle
You are underrated...
A unicorn of a person..
God bless
An old time fan, mainly here for amplifier repairs, just discovered this new format, and i gotta say im loving it!
I build this exact box with a 10 inch sub over 20 years ago. It worked amazing.
I built this wicked one full scale for 2 kicker L7 12s about 15 years ago and goodness goodness, for metal and alternative, it was incredible!!!
Also, same results at full scale. When I had my window down or even cracked.... it came ALIVE... so so much more so then when the windows/doors were closed.
@@Basshead40I’ve been meaning to upscale it to 15’s but math lol
@Always Lost Lawz lol yeah its definitely not your average enclosure build huh!?
@@Basshead40 the plans they have is straight forward for the size they give but think when upscaling it, there was something I didn’t want to figure out back then maybe one day though lol
@Always Lost Lawz lol yeah I hear you. I just had to make it back when. I still have the plans on the ol external hard drive 💾 lol. Been eons but goodness I was thoroughly impressed when it came to bands like Tool. It just utterly pounded for metal.
LOVE this series! Looking forward to silly designs 😂
I’ve been waiting years for someone to test this box, I love this series
I constructed a full sized Wicked One enclosure years ago and dropped it into a '93 Honda Civic Si firing towards the rear. Enclosure ended up being 36" x 36" x 12.5" and slid right between the strut towers. JL Audio 10W6 drivers were used with something like 600 clean watts. The setup managed to pound out 159.6db @ about 60hz I believe. It was unbelievable at the time. I agree, for metal and alternative etc it was absolutely incredible. Jazz was insane as well......the "Iguana" album from Ray Obiedo comes to mind as being quite impressive.
Hell yeah i love this series
Good job Jeff. Sam thanks for doing this test. Do the Imperial!
Thank you! I should be thanking you, it was your idea! 👍
Sam should bring this series back...
Ha haaaa! The old wicked one came good lol. Do well dude xx
Best speakers i have ever heard, were home made folded horns my dad made in the 70's with 15" drivers. 4'x'4'x4'. They hit so hard and got extremely low. Those powered with my Sansui 9090db, sounded better than the Klipsch La Scalas. They were not sealed on the front, like this one is though.
Your excelling into a new arena of acoustics, approaching that master level.
Combining your years of on hands and tens of thousands of hours of experience. Honing in tuning in in to a higher level of expertise.. good job I’ve been watching you for years develop and become a master at your trade 👍
Decware FTW! 😄
Imagine if it had both chambers as intended.
Glad you are posting new music! I have really enjoyed some recent ones like Funkareggaejam (Part 2) and Unidentified Invasion. Nice smooth bass and chill head bobbing vibe. Keep up the good music making as you bring smiles.
@@afriendlyguy2004
Thanks! 👍🏻🔊👍🏻
Loving the content. Maybe reach out to hexibase. His knowledge of acoustics would be good insight on why the results came out the way they did
This series won my subscription, well done good sir!
Used to watch your videos back in the days when you still had those pioneers in the proton. I really like your new series, especially that it gets super detailed/technical. Makes it so much easier to understand and gives a good impression on how much knowledge you have. Keep it up! :)
Love the series … and I see that bottle of lagavulin in the back. Good stuff.
I built 24 of the wicked one... we ran 16 one night for a Bassnectar show and just destroyed the nightclub... and the restaurant upstairs. We knocked every place setting off all the tables and broke some picture frames... it was pretty nuts.
i always liked my old ar12 acoustic research they were sealed home speaker from way back in the day sounded best of any thing i ever had .and now worth a mint
I love this series.
Also, one of my favorite boxes I've built sound and range wise was a 2 12" 4th order in a 2:1 ratio. After like 6 rebuilds and adjustments, it would play mid 20hz range up to 50hz range easily within a couple Db across the board. Could play anything and it would sound amazing and loud.
Takes some effort like anything, but a well dialed 4th will always be a favorite
This is very very well done, i love and appreciate the detail to no end! So much editing, so many visual shots! I also appreciate the time you took to film the driver moving in a second “demo” with the too off spliced into the demos with the “driver” pov! Also thank you for giving the song names, i really like some of them and I’m glad i can just go look them up
Loving this series Sam! So much informative information. Keep em coming
Well done Sir!
Loving this series nice one Sam
We appreciate you Sam! You are the man.
Great series
Good job Sam, keep on this. Cut in two in this way will have twice the horn mouth area as needed. The tuning frequency will rise and the design will not perform as intended.
Be interesting to mount a isobarric loading in the half wicked one and see if the lows increase as the box is designed for isobarric loading
was crossing my mind too thinking faster tighter response chest thumper.
Wouldn’t help much, to get lows you generally need a larger box and lower tuning as well as more xmax
Very nicely extinguished here Sam!! Hats off to this design with a astronomically very efficient layout plan.. Loved it😁 Currently have a hybrid bass reflex transmission line t-box in my cavalier.. Love the output.
Great content as always.. Keep-em comin.
This series is absolutely ace!
i built a half wicked one for maaaany years ago! nice to se i wasnt the only one :D
As much as I enjoyed this episode I couldn’t help but notice the 16 year old lagavulin 😂great selection in whiskey.
Excellent.. keep doing videos like these!
Great spl lab !!!
I am having so much fun watching this series! Learning a lot about the real effects of box designs. Really interested in seeing what horn loaded designs bring to the table. I’ve always been a LOWS lover but I gotta have right hard hitting mid bass too. How does sound quality and linearity compared between the designs. Great work! 🙌🏼✌🏼
THANKS YOU FOR THE VIDEO scaling box vids are rad
Good ish bro.
This kinda stuffs wants me to see what would happen if you used one of these enclosures but specifically built for a huge car 18 inch subs.
The coffin! You should also try that one with the driver facing the other direction and see the difference. Or, at least with it mounted the other side of that mounting face because the air movement holes in the chassis are being restricted by the thickness of the plastic mounting face panels thickness.
I did actually test that before shooting, about the box thickness restricting it, and found it had absolutely no effect mounting the driver on the other face - the area of space for the rear cone pressure to escape is actually much bigger than it looks, big enough for it to be completely disregarded by the driver! This was confirmed by RTA and also impedance sweep
Wicked!
very cool
This is beyond cool.
bro became a scientist
I was competing in dB Dragracing from 2001-2003 I love your test setup
This box reminds me of some pro audio/live sound designs with a 6th order bandpass design, which include Martin audio and d&b audiotechnik dual 18” subs. I don’t know the Martin model number, but the d&b boxes that use this design include the b2 and b22. Those boxes have the fronts of the drivers directly facing each other in the back of the horn area. And the backs of the drivers are inside enclosures with slotted ports out the front. Those have always certainly given me that punchy kick for live bands as an audience member, though I’m not sure if they can really technically be called horns?
Very interesting
There was a square body chevy that had the record last year. Everything wooden was covered in lacquer expoxy..
It looked like expensive kitchen cabinets.. lol. Very shiny.
It was a Bass Reflex design.
Would be cool to see this one scaled up.
Holy fuck Barevids slamming them deep dubstep and riddim tunes 🤣🤣🔥🔥
Just from the sound test the kicks are very potent sounding just listening on my headphones even after the TH-cam compression little bugger gets down
Are you going to do frequency response measurements at some point?
Impressive
I'm kicking myself for not working on my own yet... but man, life has been relentless lately. I also may have prioritized stuffing a couple 10's in my Samurai ☺
Really digging this Formula style acoustic competition.
Awesome vid man! I actually seen one of these boxes the other day an wondered how it would sound. Personally i liked the low lows, but get a bit disappointed when i listen to normal music. My c7s hit real low down in the mid 20s in the current enclosure, but sound like crap when playing 40 hz an above. Looking to get a good in-between enclosure, and this might be it!
I made my quarter wave paraflex box for 6.5" subwoofer pump some waves. Very loud for a 6.5" in my opinion, and crazy range. Playing down to 35Hz and upwards of 100, like 130Hz is useable I think.
I’ve been meaning to play with the original wicked one and the updated one I got the plans somewhere
Sam, I built the full size wicked one with 2 alpine type r 10". Worked amazingly.
Then cut it in half, sounded better 🤷🏻♂️
Lmao whattt
hell yeah that was cool ......deathbox next????
I've always wanted to build a Wicked One, I have a pair of 6.5 subs laying around...🤔
Actually Hexi uses JB weld for box joints and Blue tack for sealing the speakers
I know
I love this series and your stuff in general, thanks for thing. blutack is indeed mighty and i use it lots, but does it not absorb energy?
Not when squished this thin ☺
hah i was wondering if someone was gonna send this one in.
Loveluy stufff
im in the plans of building wicked ones but not shure if it will work in a home cinema
Wonder how much things change if the speaker faced the other direction on not only this build but all the builds?
😇🤜😁 came from work super late but still was so curious to watch it 😁😂 bed time now 🙌 love it G🤜🎖️
its a 4th order bandpass tuned to about 220hz
Lol. How did it perform? 😳 result? SAM didn't exactly set parameters. We can do one note wonders. Easily... every day listening is more complicated. 4th, 5th? 6th, 8th order can be done but not Easily for most the WO dosen't play super low how's it play music really well and loud.
@@nnperformance76 watch the video and you'll find out lol. He tests based on the max spl at 4 different frequencies
Awesome 👍 I am considering this type of box for two 18"s . Just curious about woofer orientation, in the plans I looked up it had the woofer magnet in the sealed portion of the box , is there any difference?
I think the only difference is that with magnet in the ported section, it will have better cooling and you will smell the coil before any lasting damage occurs 😂
Build it.. its not a one note wonder. It's not a burp spl king. But if u like different kinds of music it will surprise you 100%.
This competition is a mega 😁💎😂❤️ like a little kid after long day at work I still exited to watch 🥂🙌
What amp is the latest Old School Stereo Andeman amplifier a clone of?
Hey sam what happened to BP rebass got back into the bass scene after a while but cant seem to find a working link for the drive
Db/ inch cubed size is what really matters for low frequencies. Please give that's kind of analysis. You already have the cabin gain box. And space of the greatest constraint in a car for subs.
What are you using to measure impedance?
Definitely fourth order bandpass.
awe, i was going to submit the 12inch deathbox.
Still can buddy!
@@barevids Done. Check your email. :)
is that little thing made with neodymium magnets?
I know I am way off topic, how can you add a fan to amplifier?
new here, what is the pink stuff your using to hold those parts together?
Pink coloured blutac lol.
Hello sam Which design is good for outdoor purpose (car spl subwoofers) horn enclosure or 6th order bandpass ?
Tapped horn would probably be nice!
So have you thought about 2.5 inch and 3 inch drivers to simulate 15s and 18s yet? just curious. Even though I am running a single 12 right now, I am a big woofer guy. Something about 20 hz at around 140 Hz that just makes me happy. My 12 drops off at basically 27 Hz and a lot of the songs that I know have those low lows are just disappointing to listen to. Lol.
You can always build a different box to get the lower frequencies. My Ultimax 12s are pretty solid to 15-16Hz. They actually play louder the lower I play until they drop off under 15Hz. (Partially because of room gain I think)
of course haha, future seasons!
@@JoshM7 that's how my zcon 18 seems. Pretty flat from 18-50 Hz. Pretty much falls flat on it's face above that though. The ns4 12 I am running right now plays about 27-50 Hz. But a lot boomier than what the 18 is. 18 does basically high 130's from 18 to 45 Hz. I should have designed my own box instead of following sundown's recommendations. And with the cost of wood, don't really wanna do it again right now as I just built this box about 2 months ago and birch definitely ain't cheap.
I remember looking at Ronnies Sniper boxes doing crazy numbers on small drivers here on TH-cam. Only if he thought in joining on this....
Excellent content. How about doing a full sized build on the best performer?
yes this was mentioned in the series pilot episode :)
@@barevids Brilliant! Looking forward to it!
Cut in half? Not quite. The horn's mouth should have been cut in half as well. This would have dropped the Fb a bit.The WO is basically two 4th order BPs with expanding vents joined together.
Hey Sam, did you figure out more about the box design I sent over?
Nice video, and an interesting design indeed. Never thought about doing a bandpass horn enclosure like this. It seems like a nice high output design with a decent frequency band.
which one was that?
@@barevids The one that looked a little off when you imported the model for 3D printing. I am not that good at 3D modeling 😅
@@Skarfar90 sorry I don't recall you'll have to be more specific lol
@@barevids I'll ask through e-mail 👍🏻
I was a bit confused by the word "horn", for me it is something you use for higher frequencies. And for that reason horns are kind of "bad" since they are very directional compared to a dome that can spread the sound better. But as we know lower frequencies are not very directional, but can be a subject to "standing waves" and from where in the room you are while listening. But pure pressure and air movement can always be compaired. Interessting non the less. 🙂
Horns aren't specific to any frequency. It just needs to be longer to accommodate lower frequencies
I can’t find the song on 9:24
I just looked these up recently!! Was curious how they’d sound in a single 15 in a suv. I’m very curious if you were to install a small long (low tuned) port into the sealed section making it a sixth order if it would increase the low freq output? Anyway you could implement a small port into it?
Design it, send it in and i might print it! :)
@@barevids just make it episode 4.2. Modifying the wicked one into the wicked one v2. Print out a small aero port or find a small 1/2 or 3/4 pvc pipe and turn the sealed section into the rear ported low tuned chamber and see if there’s a gain in the lows! I’m not up on my design skills to be able to send u anything. But in my head I feel I can design with the best of then and I’ve read so many forums and articles about box design. I’d also like to see some tline designs with a 1/3 offset driver location. There’s a guy on one of the fb groups that’s always ranting on and on about some magical 1/3 offset driver ratio tline that has more output then any other design out there. His name is Paul Ryun is his name I think. Seems to know his stuff
I might consider it for an end of season special. This might be a great opportunity for you to learn 3D cad tho and turn some of your ideas into real models. Freecad, fusion360, sketchup, all freely available ☺
@@barevids I enjoy learning how different enclosures effect how a speaker plays and this season your doing is freaking awesome! You can read all day but your taking someone’s word for how “it” sounds. Trial and error seems to be the best teacher. I’ve cut and modified my simple 4cube ported box 12 times until I got the best sound I preferred. Started with a 2inch tall 20 wide port, wasn’t enough output so I went to 5 inch tall 18 wide =a lot more output but at a higher frequency so the. I extended the port 16 inches externally. Now it has lots of output and plays pretty low but falls off on the high frequency so now I’m thinking 6th order to gain the higher frequency output, but then I got to reading on tlines and I have no personal experience listening to them but I believe I will enjoy their sound more bc they’re suppost to be more accurate and go really low. But then I’m like what about the higher frequency? Should I expand the line for a horn loading effect for higher frequency? So many options but so expensive experiment. So this season your doing is right down my alley! I’ll check out the cad designs and see if I have time to figure it out.
Very very nice bro!
I Suscribe now! 😁
Can you share the plan in millimeters please?
I'd like to see the Bill Fitzmaurice autotuba evaluated by you.
Submit it and I'll print it!
What is this watt meter you speak of. What is the model specifically? Thank you in advance.
A have a short video explaining it 😎
😍
When you did the demos did you use higher pitched faster music and slow the video to put it back in the bass range?
all explained here th-cam.com/video/Nq4KWMBR8Yg/w-d-xo.html
@barevids did you find that a helmholtz resonance scales up like that with box dimensions?
Did you find that a box with 8 x the volume, twice the port length and 4 x the port area gets tuned twice as low?
@@TimpBizkit helmholtz resonator uses the fluid dynamics of air which scales. This series is scaled by a factor of x6. That means the frequencies are multiplied by 6, port area divided by 36 since its 2 dimensional, and box volume divided by 216 since its 3 dimensional to create a small scaled version of a full size enclosure.
👍👍👍...
Very cool video. Those wicked ones are neat boxes for sure. Would you be interested in testing a parallel 8th order bandpass? I could scale down a 1/4 of my van's 8th order and send you the specs or maybe toss it into an stl for you to print. Just will need some info on the speaker you're using to verify a few things. Videos of my van are on my youtube channel. It's 4 DC Audio level 6 18s on 2 DC Pitbull 20ks. Usuable bandwidth from ~17hz to 80hz. It did over 160s even with 3 of the subs having loose push terminals causing them to get different amounts of power and fight eachother lol.
Just saw the link to your submission video, I'll see about submitting it.
I've had experience with 4 of these boxes and used one in competition. I believe you have it way too close to the back wall. needs about 1-1.5 feet of gap to get the full effect of the horns backwave. best sounding box I ever built.
Agree to disagree. Not sure of ur vehicle 🤔. Had a 99 suburban with this box about 6 inches away from the rear. Insane!!!! But Agreed best sounding boxes I also built. But just... looking forward to see if Sam builds the others?
@@nnperformance76 Nothing to disagree too good sir. I had it in a '91 civic hatch but I actually have to put the wicked one into my friend's 2 door Tahoe for fun and the box was also 4-6" away from the back door. Had so much bass had to turn the gain down also box broke all his roof braces lol. Sounded crazy especially on movies. This box in this vid seems super close in my opinion. Glad you got to experience first hand. Barevids says it's nothing special but you and I know the full size dual version is very very special lol.
@@nnperformance76 What subs and amp were you using?
@turblown it was over 20 years ago. 10" Pioneers can't find them anymore high sensitivity and low fs. And some Sony switchable voltage rail amps. Nothing fancy but one box was the 36x36 and the other was 36x24 or 28. So 4 10s in 2 sized wicked ones in a 99 suburban was great. Musical...
what if you ported the sealed size of the enclosure and tuned it for the lows.
it would turn into a 6th order and become very peaky at a few frequencies above 60hz. Sealed section too small to put a port in there long enough. Dual woofer box hits mad lows and crazy kick too
now we need someone to convert the Tuba HT horn into a 3dprintable box :D
I sent the plans to Sam. I'm not good with the computer stuff.
Imperial vs tuba? I built the wo & Imperial. Imperial is crazy 🤪. Never built the the tuba? Would like to see ...
I've already submitted it. It's the tuba but with slightly rounded corners.
@@JeffArend sweet👌😁
Anybody got a "helmshold" counter?
