Save Trunk Space With This Subwoofer Design - Infinite Baffle - 5,000 Watt Test - Skar Audio EVL-18

[@mikeallover]

25 years ago we did 2 12” pioneer free air in a Beretta. The baffle was across the entire back seat rest. It hit real low with that big trunk.

[@jaz97]

You had me at Beretta LOL so 90s love it!!

[@grandam]

I did this in the late 80s (1988) 2 Pyle Driver 15s on Punch amp in a 1980 Oldsmobile Delta 88 4dr sedan. Stupid big trunk.

[@BudgetBassHead]

I also loved the Berettas. They were definitely one of the coolest car back then.

[@odogrollin]

If you decide to do infinite baffle again, my suggestion would be too frame out the opening of your trunk. That way you can mount your baffle to it. You will get significantly better bass response, and that s p l number will come up significantly

[@jimbobdobbs1597]

​@@BudgetBassHeadmy mom had a grand am and as much as i hate pontiac, i would buy one (acoustically) today

[@Mantoollingo]

That is not infinite baffle. You have to completely seal off the front wave from the back wave, the side with the towels and the amplifier gap is not sealed, and then the deck lid is not sealed either. Best results would be to completely seal the baffle and run with the truck open for true ib, this is just free air. I do like the videos and style of testing you do. You always keep things interesting and fun to watch with videos like this!

[@jeffunrau3958]

This is free air not IB

[@Alkatross]

This is not free air. It's a leaky infinite baffle

[@jt9264]

Yup, not an IB setup, losing a lot of performance from that opening on the side

[@jacobkelly7502]

he knows that. He stated that in the video. told us its not a finnished product up front.

[@jt9264]

@@jacobkelly7502 his last trunk setup as well he called a IB which was finished for his 18” skar sub

[@bojow8102]

I dig it 👍🔊🔊 Only thing I would suggest to add would be some pool noodles around the edges to seal better. I've seen a couple of builds that use pool noodles for cheap way of sealing gaps. Thanks for the videos.

[@BudgetBassHead]

Thanks for the tips!

[@adammarsden2643]

The sdr's are probably higher 'q' drivers than the evl's are. You need kinda higher 'q drivers for free air subs

[@91CavGT5]

Last year I built an infinite baffle subwoofer setup in my old 2000 Toyota Corolla, with a twist. I used eight 6.5” 8 ohm woofers from PartsExpress that were $8 each. They were ran off of a D4S JP8. The baffle was completely sealed. I used aluminum duct tape to seal holes and a little spray foam here and there. It had useable output down to 30hz with output going down to 25hz, but it was dropping off really fast at that point. It sounded like a couple of cheap 10” subs in the trunk, but took up zero trunk space. I’ve got a video on my channel showing it.

[@Mark_5150]

I thought this was a reupload. :) Maybe change the title to "Round 2"

[@grandam]

I did too!!!

[@BudgetBassHead]

Wow. I'll look into. Thanks for letting me know that!

[@dreci3001]

I like the Battlefield theme, brings up memories. Nice production, from all the boxes that can be built, IB is the least $$$ in terms of material, but renders the trunk of a daily useless....and probably loss of 3 seats. In home audio IB sounds shy on bass, but cabin gain does wonders. Great video. P.S. As I have written before, get that SPL meter out of the foot well, bass-waves are long for a car, but stuff in the cabin reflects differently, so get it close to head high, not on the window, but close to head high. P.P.S. I almost mixed IB and OB, IB requirements for a wall of 2x18" in a trunk has maybe 30% of size required for baffle size, the trunk cutout is severely smaller than what an IB requires, bass is still longer than car, so you can use trunk as a box, making it OB, which 18" love as sealed boxes using the trunk volume. IB has a huge WxH measures baffle depending on speaker size. With all the losses you have a 4-6BP box with or higher order, depending how sealed the car is.

[@BudgetBassHead]

Good suggestion thanks for sharing.

[@edjackson4389]

Another good one!! I like how you give alot of clear details on everything you're using

[@BudgetBassHead]

Thanks I appreciate that 💯

[@wow1022]

this is the most powerful and well sounding setup you can do, unfortunately it's difficult to brace and seal the trunk well, and to get the best sound you have to open the trunk

[@icarusrising728]

Youre funny my dude lol... the Fs of the driver is going to be your peak in IB

[@itsalwaysfriday9766]

Thanks for the video. Getting my stuff gathered for my IB set up. Driver needs to have high q, high xmax, and low fs. Dayton UM 18 (.7, 22, and 19 respectively) is one that has all three and is waiting to go into mine. Planning for it to be the winter project.

[@BudgetBassHead]

Wow. That sounds amazing. Its not easy to get that loud below 35Hz.

[@1ohmwrecker]

@BudgetBassHead I didn't know it was that good till I head some other ppl tell me what u just did lol. That's with a smart bass 5k. Hopefully maybe a big boss 8k will get me that 150! On music it bounces between a 140 and 146 or so.

[@scottbe1]

IB?

[@Laserred01]

I'd say the EVL has too low of a Q to be good for infinite baffle. The SDR has a Qts of .69 which is pretty close to ideal. I'd also bet the SDRs will beat the EVLs in SQ (which is usually why you do IB in the first place) and probably match DB (especially down low) to the EVLs even with much less power. That is... once you get that setup properly sealed off. But yeah, not bad for just throwing a board in the trunk with some subs attached! I really want to make one of these setups in my 'stang although the PR setup I have (1-12"/2PR) is hard to beat for a small box.

[@davidperry4013]

You should invest in some nice sound quality speakers to complement the SQ of the infinite baffle sub setup, like Sony Mobile ES which is reasonably priced and does punch above its weight in sound quality. They also get louder than the stock speakers.

[@roughboygarage1475]

Pretty good spl results for freeair!

[@joemeyers1016]

Give the One Audio IB3's a go in that setup!

[@BudgetBassHead]

[@bartowflorida]

SDR has lower Fs and softer suspension, which is probably why they sound better on music. I hate the EVL.

[@2002ZRX1200R]

Subs with a lower fs and ebp are king for ib.

Did you also seal and audiomat the trunk from inside? Or does it rattle like a ghetto slab?

[@cristovalmontoya5222]

Would it be better to seal off your baffle I can see the amp in your trunk from the inside vehicle ?

[@subdynoman]

I wonder how a pro audio sub would do? There was a nice 18 for $150 that i wanted to try a pair as an IB setup. Im sure the Ultimax would do well here. I still am not a fan of this unless its a diy buget build. But, give us your opinion on how it all sounds and how it all compares in practicality.

[@tigerskone2945]

Two 8s in Ashland or ported box would sound better than that setup.

[@tighttdasbino2928]

30hz and it sounds balanced though the whole frequency range. Nice 🤔

[@evilinside5984]

@BudgetBassHead- What setup sounds the best, the SDR infinite Baffle, or the 2-12" passive radiator setup? I would have liked, to have seen, SPL scores, @ 20 Hz, 25 Hz, and you skipped over 35 Hz, with this EVL infinite Baffle setup. Great video❤️

[@BudgetBassHead]

Thanks for pointing that out. I would have to say that the SDR setup sounded better. The trade-off would be losing access to the trunk from the inside of the car, and back seat-down listening only.

[@evilinside5984]

@@BudgetBassHead - Also this Infinite Baffle setup had a very flat bandwidth, doing a 142 Db @ 30 Hz, and a 143.9 Db @ 50 Hz= very flat. I bet if you drive around playing/breaking these subwoofers in for a few weeks, then ✔️ the Db again, but @ 20, 25, 30, 35, 40, 45, 50, 55, and 60 Hz, to show how flat the bandwidth is, would be great to see. I hope you consider this, plus would be great to get your opinion, on how they sound different after being broke in.

It isnt a infinite baffle you arent sealed

[@TheScottishbear]

I'm running two 18" Peavey Black Widows IB with a front sub in the glove box area. 2005 Ford Focus. I would like to try a ported setup but IB just sounds to good. So fast and accurate. Esp. when it's t/A (time aligned) When I watched one of Matt Bogardt's videos (of Image dynamics); he said to build an IB baffle with five sides for strength. So essentialy an enclosure without the rear panel. I just built a super stout baffle and used 3/4" hardware to secure it directly to the car. There is little to no vibration. It's so musical it's really hard to go back to boxes. I'll admit I do miss my wall.

[@BudgetBassHead]

That sounds very interesting.

[@anubisprince36]

Peaks at 30hz because of Fs

[@tayloremriectx]

Unfortunately if the rear of the subwoofer is not absolutely, and completely sealed off from the front part of the subwoofer, I mean COMPLETELY SEALED NO HOLES. Its not infinite baffle. Because the wave that the subwoofer creates can not be able to make its way to the front of the subwoofer. It can if there is a hole.

[@scamchan]

I need to try an 18 in my setup. Just for fun!!

[@towerklok125]

You sealed the sdr better that’s why your noticing a difference your getting a bit of cancelation.

Yeah you definitely inspired me on the SDR infinite baffle still wish I had the SMD tool to know how many watts on bushing cuz I have no clue I think I might be at 600 and I know I can go way more put on never be able to afford that tool is there any other tool on the market besides a multimeter do you know exactly how many watts I'm putting out
