No Other Design Sounds Better Than This - Infinite Baffle - 8,000 Watt Test - Part 1 

My pops always talk about the 2 kicker free airs he had in his 79 grand prix... Would love to hear how these sound in person

@Kfmeden Man they sounded good back in the day, nice and clean. Saved a lot of space too....

I had 2 MTX "enclosureless" 15s (the grey and pink ones) in an infinite baffle setup back in the early 90s in my 2 door Chevy Cavalier... Ran off a Kenwood 821 amp. That thing slammed for it's time.. Ahh the memories bro.. haha

Thanks 👍 This was simple and LOT more impressive than expected.

I like it!

@BudgetBassHead wus the name of the song?🔥

​@@BudgetBassHead what did it cost? Thinking of getting bk in the game been out since 13

@@michaellazenby6712 The scar audio SDR18s are less than $150 a piece

Agreed. Takes out that strained sound from the bass/music.

@@wilsonrawlin8547 We are talking about subs here, todays monoblock amps are meant to be used at 2 ohms or below, running at 4 ohms is a waste of available power, He is running this at 1.2 ohms. nobody wires subs at 4 ohms??

@@jimhanson8370 Not true at all many SQ people run at 4 ohms for cleaner sound. BTW I didn't same a damn thing about what Ohms to run your monoblock subs at.

@@jimhanson8370 not true, the car audio shops always wire systems up at 4 ohms. I didn’t learn about 1/2 ohm until RU-vid. And I’ve had sounds in every vehicle since a teenager. I’m 47 now 🔊

​@@jimhanson8370 What are you smoking? Nobody does 4 ohms, unless they're doing 4 ohms. How many amps have you burned up?

Thanks for sharing

looking at this video, when i’m finally over my hard hitting 15 in a huge ported box, i’ll definitely try this & get the most out of my 15’s SQ on clean power! i’m sure you purely hear the sub frequencies in the music and no extra rattle or tones!

Explain what “speed” of an 8 inch sub means. A 15 inch sun playing at 33htz moves 33 times per second. A 8 inch sub playing 33 hertz also moved 33 times per second? So how is one sub faster than the other? I’m not trying to be a smart azz, just trying figure it out!

When referring to “speed” of an 8” sub. It is reference of what also may be called attack & decay. How fast a speaker starts and stops when producing a frequency. Attack is how quick it starts, decay is how slow it stops. Due to sheer size\mass differences between an 8” and 15” sub, the 8” will start and stop quicker. With an aperiodic style enclosure, this dampens the speaker in an ideal way. It helps large subwoofers stop much faster. In essence you can select a slightly higher crossover frequency as the larger sub will react with less unfavorable effects. Ie. say 80-100HZ versus 50-60HZ for a 15” sub. Hopefully this helps with my initial statement.

What's the deal with horns? I hear a compression horn can act as a mid and tweeter simultaneously and highpass from like 400hz up. Is it in any way possible to have an SQ setup that's 3-way (sub, midbass, and whatever, or sub, mid, and tweeter) that gets 145-155db on the sub stage with the front stage more or less keeping up with it? (more for the low side of that SPL, less for the high side) Size constraints are a small single cab truck with a manual trans (so no speakers in the kick), and I only want to use AT MOST half my truck bed for the blow-through box(roughly 16.5 tall x 40 wide x 36 long/deep dimensions, can extend to 17 tall x 52 wide, but only 20 deep if doing a slot loaded IB blow through with three SI SQL-15s). I'd really prefer than nice round 150, and 155 is about my soft tolerance limit for bass. Haven't heard a 160+ car yet from the inside and kinda don't care if I do since that's not a goal of mine.

@@Drunken_HamsterTitanium Diaphragm compression drivers play a higher frequency and can be used without a tweeter. A phenolic diaphragm compression driver can be used to play the midrange frequency’s. Titanium Diaphragm (1500hz and Up) Phenolic Diaphragm (500 and Up)

@@ShaahidJohnson Sounds like I'd still need two drivers to cover the midrange and highs. If so, wouldn't I be better off just sticking to the traditional midbass+mid+tweeter combo?

100% agree

I have a box like so many others, works well but there’s always the space issue. IB is definitely getting a hard look. Beautiful and functional solution if you’re into SQ.

Hell yeah! I love me some titebond 3

Although a large ported box with a low tuning will sound similar with extra headroom in the bass extension, or just adding a pipe that treats the trunk as a slightly leaky ported box and have a 15Hz tuning. The low resonance won't cost you output up higher either compared to the same infinite baffle. Whilst you can use your trunk space, it will restrict the sound a bit.

Wow you crazy just my type gangster shit 😍

IM TRYING TO DO THAT EXACT THING RIGHT NOW!!!! ANY IDEAS OR TIPS PLZ

@@Sebastian-vt7fe really depends on the car and your fab skills and size subs

Don't go to Rockville they're s***.

Thanks for the support Steven!

Hey would this set up be better than 2 sa 15’s

Why is infinite baffle better for sq?

@@jmohammed5487 Flatter frequecies across bass bandwidth. Less peaks.

why would IB be better.. wouldn`t the trunk rattle

@@QuezJ81 that`s what you get with a sealed box, id be very surprised if a IB would sound better then a sealed for the vast majority of cars

Excellent tip! Thanks.

It can also change the way it sounds , like filling up the trunk with luggage would. Decreasing airspace. Could be better could be worse? Ive never had that car or those particular subs so i wouldnt know. The mesh and cloth would allow air to pass through, but at a much slower rate.

@@Hayawasa No, the expanded steel and cloth has no effect on the flow rate or sound.

I need to do my Acura like this

@@JasonWW2000 you have tested this and know 💯 that it wont? I have and aside from what i said the mesh can put runs in the cloth over time from air making the tightly streched cloth vibrate against the metal and unless you attach it in a permanent fashion to the trunk metal its gonna rattle like crazy

This setup genuinely surprised me!

That will make a great test. Thanks.

I’d say squeeze the subs together and port it into the cabin

MTX Eliminators

Yes ..Yes.. I did that (cerwin Vega) in 1986 with a 1968 Camaro.. Rockford Fosgate power 650.. pioneer mid & tweet... with a Kenwood pull out cassette radio...fond memories

Correct....I remember them particular drivers knew someone had a pair in a sealed box in a hatchback an it banged

True that.

Not exactly. It’s not sealed at all. The point of IB is only to keep the front wave separate from the back wave. There’s no air suspension like a sealed box so the driver has to be rated for IB applications.

@@rickcharles5667 True that it’s not totally sealed however it will still be more than if the subs were out in the wide open

Once the Q of the system goes down to the Qts of the subwoofer, you have "infinite baffle" even in a box. At that point you just have to deaden and fill the inside of the box to kill reflections. Should play nice right to the Fs of the subwoofer@@rickcharles5667

im done with boxes. this is the way to go.

Glad you like it!

@@666Necropsy The first time I tested a dipole sub with some super crappy 12" in a small room, I was instantly amazed because of the details. Even though the sub was totally busted. I kept thinking about it and ultimately got a car that had a trunk that was almost like made for having a sub in the middle. Did an install with good 12" sub and fell in love about the idea where there is no enclosures (for the bass at least). Then after years I got two 18" Electro-Voice DL18MT's, old 90's PA subs for cheap and just fitted them on a big board. I tested them outside, as I'd been dreaming of a sub bass capable small(ish) PA -system that doesn't make the neighbours or anyone living nearby mad (even at like multiple miles away). Nowadays I myself pretty much hate the overly high SPL -oriented cars blasting some single note bass songs nearby. So I can imagine how it would feel waking up or noticing a bumping bass when you're going to sleep that just keeps on playing forever (in your usual forest raves, from 10pm to like 6am+). For example one time we had just one simple big Peavey 2x18" PA sub enclosure and in the beginning of the night a few of my friends went close to the nearest house, more than a mile away (which also was behind a small hill) to check if the bass carries to there and when they got out of the car to listen, they said it sounded like there had been a party going in the nearby house. I've tested the two 18" in a large wooden building and they went nicely down to 20 something Hz. One time I took them to a DJ gig in a really old bar in a wooden building. There I had some problems with uneven bass as I didn't have enough time to EQ the system. I also had a pair of 15" "modern" car subs and they too sounded great outside WITHOUT an enclosure. And I bet the bass couldn't be heard after like 50 meters or so, but the first 10-20 were very nice. Inside an aparment they would shake the floor with Indigo Children (JLE Dub). When I had the system in my car, I noticed that on the outside, the bass seemed to attenuate on the sides of the car, which makes sense as it worked kinda like a dipole. So I think one can blast their music much louder with a free air/infinite baffle sub system than they can with any enclosure without messing with the people around.

You not tripping

I say, 'Go for it!'

@@BudgetBassHead l like the way you think. Now just to convince my wife lol

It sounds like crap with seats up. Almost becomes a fourth order bandpass. Rattles the trunk like crazy, but about a 50% loss of sounds in the cabin. I have to crank the power to hear it properly, which these subs can't handle. I would need the ZVX-18's to play with the seats up.

I have a single 15 hung from my rear deck so I could retain full function of the back seats. I'm not an spl type guy but who doesn't love bass.

My Fairlane show car has four 10's in the rear deck

​@BudgetBassHead in my 2015 civic sedan I cut the rear folding arm rest with a ct sounds meso 12 inch Made it custom all the air would travel inside the car . The meso 12 gets extremely low for a box tuned High . Sounds really good

Works for me. The trunk closed is the box lol. And it wangs

I really hope you guys like this build as much as I did!

Ear buds play low frequency 😂

This is the build, you just take them outside first and set it to 5 and let it rumble the neighborhood with a low vibe; quote a box price of $8000 and from the look on their face adjust the price/bass accordingly. If they wrap their legs around you and kiss ya, then you turn the bass way down of course; all negeotions first before romance....

you are very wrong, you dont need a ton of power for this, just a good seal and sound deadened cabin, check out ps sounds for these setups, he doesnt even have much power to begin with yet, he can make hair tricks

@Aaron_Jones No I didn't apply any 'additional' treatment, just yet. But I do plan to seal the entry a lot better.

I have to agree with you Josip. With the lack of compression, a lot of power wasn't really necessary for this build. When given a clean signal, it simply sounds good.

@@BudgetBassHead im having a hard time deciding making a good sounding wind machine against a big heavy box that will just get louder, but not sound as clean, if the infinuite baffle dont sound good, i will still have a baffle to use for a box, weird shape of the trunk is a pain in the ass, id rather just make a strong baffle, run low power and not have to worry about anything, hopefully

Sealed would be extremely louder. But I'd lose my trunk

Thanks for the tips.

I have my DSP set to roll off around 25 Hertz. Primarily because I don't listen to anything that low in my car. I'll be sure to mention is in future videos

@@BudgetBassHead I wouldn’t change my dsp tune either! 😂 after taking my own crash course with a helix dsp , I can tell tuning isn’t something , I at least ,want to do twice!

I agree. This setup has real potential

Beat is Damma Beatz - Fast Vision

So very true 😄

Is something wrong with skar?

Thank you very much!
