Great timing on this video I never gave shallow subs a second thought until the last few weeks I am buying a vehicle with a factory subwoofer installed and been considering my options to utilize the same space. Glad you have confirmed that Hoffman's law still applies here :)

[@DIYAudioGuy]

It's a good sub, it just needs the right box.

[@jrwinckler6744]

What’s your recommendation for a sub for a sealed box?

[@mullinperformanceaudio5902]

Man this video couldn't be timed any better. I was talking with a friend today about building a box for his Tacoma to go behind his seat. This is pretty much the exact same situation he is running into. He keeps thinking big...big...big! I keep telling him it takes space to make bass also.

[@DIYAudioGuy]

Yep, wife had a craft show this weekend and I managed to get her set up, work on the demo rig and get her tore down and packed up. Thank God I'm getting a back injection tomorrow. Lol

I built a box for a DD shallow 12 it's 4.5" deep 1.48 cubes tuned to 30hz it replaces the floor cover for the back of my Kia and you still have access to the spare tire

[@josephsaucedo8691]

You brought up a good point you can make a really small box but most thin subs still require almost the same amount of air space as a full size sub you save on depth size but you end up with a wider and taller box to get the air space 🙈🎶👌✌️👍💯🥂

[@DIYAudioGuy]

Exactly!

[@Onizukachan915]

Which is great for truck boxes, probably not great for anything less.

[@carrickdubya4765]

NOT !!!!

i have the 2 JL audio 10TW3 , in truck style boxes vented and they really surprised me on the sound coming out of them. i have a 2010 element and i still have plenty of trunk space and i can easily remove the boxes if i need more space.

[@sudd3660]

i hope there is going to be some dsp testing on this subwoofer build, i think you can add large amounts of dsp in the form of parametric eq with no ill effects. but would like to see others try it out.

Interesting to learn more about the analysis and what all goes into this stuff. The NVX N series with NVX duel sealed enclosure in 10" is one that I have sitting in my cart at SE while I continue to research and learn more. I don't understand much about the different specs like F3...

[@DIYAudioGuy]

F3 is the three db down point.

[@Grommet2007]

Looks like you built a perfect-sized enclosure for measuring the Vas of 12" drivers via the delta-compliance method 🙂.

[@DIYAudioGuy]

😁

[@alext2664]

I think this form-factor is better suited for an active+passive radiators setup, something similar to what Hertz used to do with the EBX F25.5.

[@DIYAudioGuy]

Either that or DSP.

Great review. That NVX looks like the Massive Audio slim 10”

I see you hit that box with the 45° chamfer. Probably my favorite edge profile 👍

[@DIYAudioGuy]

Sometimes I do a round over, sometimes a chamfer.

[@AGP187]

Does the shape of your air space inside the box matter? Like with that shallow box you built, could it simply be built wider and keep the depth to gain the space you need?

[@gwf82]

I'm currently using the 2011 pioneer shallow mount 12" subs in my regular cab silverado. I was a bit sceptical about how much bass they would put out but they surprised me. Pioneer recommends .5-1.0 cu.ft. I originally had them in a really small prefab enclosure which gave them .55 each and they weren't half bad but I could tell they were being under utilized so I found a prefab box that would fit my truck that gave them .85cu.ft. each and boy did they open up. They put out bass I never thought was possible with a shallow sub. I later on purchased a 3rd one so I could cram 3 behind my seat but personally don't see the point.

[@DIYAudioGuy]

Yep, got to have the right airspace to get good sound.

[@jasonkimes7784]

I just built a 1.4 cubic foot box tuned to 30 hz for a couple Pioneer D series shallow 10's. They sound good and have pretty good response down to 30 hz like I anticipated. I may end up running a single larger sub with more xmax with a Skar RP 1200 amp I just picked up. Currently running the Pionneers with an 8701 800 watt Pioneer digital amp.

In your follow-up video, it would be interesting to attach your DATS to this one and just check what the frequency response is on it anyway.

[@DIYAudioGuy]

That is a good idea!

[@0357predator]

I have KIA picanto 2013, where to put it and how big the box should be pls? Planning on 8' or 10' subs.

[@RK-ci9nn]

Excellent video! A great point to make though, in situations where space is super limited, it is worth considering smaller subwoofers! Typically, your normal 6.5" or 8" subwoofer only has a mounting depth of 3-4", requires 0.25-0.5 of air space per driver, and might even sound better than the restricted shallow 10" or 12" you'd try to squeeze back behind the seat of a truck. It's all a matter of picking the right subwoofer for the right application.

[@DIYAudioGuy]

Good point!

[@jellyg.8961]

That's probably the route I'm probably going with my Yaris hatchback. The trunk is already small and I use it everyday to carry lots of stuff so the best spot for a sub box is below the front seats.

[@davidallison976]

Most thin subs are actually a FS around 45hz. Really a good relief for the 40-80 hz to fill the shortcomings of 6.5 midbass. Gotta have the big box to hit the low bass. They are great under seat or a front sub. I have a couple 8’s as front subs in a super small box. Still have to have the bigger 12’s in the trunk!!

[@jasonkimes7784]

Good stuff as always! May I ask what kind of table saw?

[@DIYAudioGuy]

It's a sawstop.

That backplate is a pretty cool accessory

[@DIYAudioGuy]

That is what I thought. I see a lot of builds where the builder makes one out of wood. But it sticks out from the back of the box 3/4".

I drive a regular cab 81 f150 I've got 2 10s and a shallow 12. Love with setup but one day I plan to put shallow mount jl 13.5s. I thought about just building a single 10 or smaller not shallow 12 in a ported encloser. It'd be a neat experiment for that compact of a space.

[@seanmcguire6998]

72-78* is a good range for matching car seats. I haven’t had very good results with shallow subs - may as well just go with 6.5” woofers to get good sound with a small enclosure.

[@89Malvarez]

Hey! Great video! I was wondering were I can get an aluminum plate just like the one is provided with the NVX sub? To use it with a different brand shallow sub. I was looking at NVX webpage to see if I could get a "replacement" but there's no options. Thank you in advanced, great content!

[@DIYAudioGuy]

No idea. It would probably be easy to make one.

[@kelbaez]

have you ever played with the idea of a round shaped boxes? I know they are difficult to make and waste more material, but I've always wondered on the sound of those enclosures that sit inside the Spare tire.

[@DIYAudioGuy]

There's actually been quite a bit of research on the subject. It's too much to cover and KZbin comments. But for a subwoofer the most important thing is the airspace, and putting the enclosure inside of the spare tire is going to limit your airspace. Removing the spare and putting the subwoofer in the spare tire well is an entirely different thing.

[@kelbaez]

@@DIYAudioGuy I wonder how much difference would the space make on sound quality and loudness one vs the other. I currently have a Rockghost and Im very surprised with how well and loud it is on that small footprint. But they use a custom design with plastic and metal. I wonder how an MDF custom box stacks up.

I "dry-fit" all of my speaker/subwoofer projects by drawing them to scale in Microsoft Visio. You can see examples of the drawings I make at the end of my subwoofer videos.

Hello I have a 2020 grand Cherokee under the driver seat there is a cubby area that’s approx 14” long 10” wide and the cubby itself approx 10 “ to 12” deep with a lid that covers it . My idea is to put an 8” JL 8w3 in the lid mounted to the lid with a 1” plastic spacer ring on the top and 4 1” mdf rings to go into the inside of the cubby with the sub . My question is with a small airspace like that am I better off leaving it sealed or trying to add a small hole to have an air port to let some of the air out ? I know for large enclosures you typically want porting but with limited air space idk which way would be better . Thoughts ? Thanks . Btw I am trying to keep all factory looking so any visible enclosures are a no go at the moment . Thanks .

Could you add a 2” aero port on this and get more boomy bass? Or would it sound horrible? Thanks.

No, I built this box just to show a tiny box in the video. I did a build with a larger box with two 2" round ports kzbin.info/www/bejne/hJvSnXxjhKp7e5osi=JHSSsYgoXhGyNtO5. Aero port is another name for a flared port. If you are using a slim sub you probably do not have room for the flares.

[@nighttow8780]

Oh I see they have learned many lessons with the leads coming from the terminals. I have had several break off under high excursion. Not the shallow version though. Especially when the glue overheats and the spider, which the leads are woven to, separates from the basket. I've been trying to follow nvx for a little while now, I believe I'm seeing what I would call Rapid iterations. I'm seeing updates and new versions popping up quite frequently on the nbx website. These shallow subwoofers being one of the newest. I'm sorry if my comments always come off as negative. They are simply observations that I am expressing. I am actually quite fond of nvx. My daily driver currently has nvx 6 1/2 component, 6x9 component, and 3 1/2 inch coaxials topped off with two nsw 104 mounted inverted and boot removed from the magnet for cooling purposes only, (these things really do not like heat) on 460 RMS in a 1.5 cubic foot sealed enclosure. Everybody constantly asks me what kind of system do I have? JL audio? Alpine? One guy actually asked me if I had a complete focal system. When I respond with nvx, generally the next question is, who's nvx? I generally begin my introduction of nvx to these people by turning the dial clockwise.

[@DIYAudioGuy]

They have been sending me gear to try out and it has been good stuff. Looking forward to getting my hands on some of the bigger subwoofers!

[@nighttow8780]

I agree, it is good stuff. The only failure I have encountered is the glue melting allowing the spider to separate from the basket which as you know, if this goes unnoticed for long, leads to the complete destruction of the speaker. Out of six nsw10s that have circulated through my daily driver, three of them had the adhesive fail which led to catastrophic destruction. However, the most recent two I have purchased, I reinforced the glue myself. These have not experienced any failures, and I am able to drive them as hard as my little amp will go. They get warm, I wouldn't mind seeing the next generation of N series subwoofers having not only a pole vent, but also basket vents between The Spider and the magnet. I do believe this would conquer the Heat problem. I contemplated drilling some holes in the basket myself to help cool the coil, but then I decided not to just in case. But I am definitely a fan of nvx. The price to Performance ratio is unmatched in the industry. While I was purchasing these six N series subwoofers, they were running a sale where you could purchase two for $89.99. I hopped right on this and purchased three sets. I like your nvx content as well. Always looking for new information on their products.

[@DIYAudioGuy]

That would be cool!

[@gypsy6211]

@@DIYAudioGuy they actually make sub boxes designed specifically to mount in walls, generally made from fiberglass, but those are expensive, the only issue with a direct fit being it's power limited, too much internal pressure will blow the drywall though the screws 🌬️😂. But if you encased between and using the studs before the drywall went up, you could get a really well planned box tune for that sub, and in a living room with limited floor space a movie would feel/sound awesome. There's @ 2.6cu.ft in most 8' walls between studs, so there's room to add wood front/back and sealed, and still have a large overall box.

[@DIYAudioGuy]

Unfortunately most prefab boxes are a bit undersized. It will not be optimal, but it will still work. I find it odd that the enclosure manufacturer recommended brands. That sounds to me like marketing mumbo jumbo. The box does not have the slightest idea what brand subwoofer you are using.

@@DIYAudioGuy it's a gp audio truspec box. It was designed for a sundown SA, but they listed other subs which had similar specs.

Tech question for you... I have a pair of 100w RMS mtx speakers that were brand new but sat in storage a few years. Im getting bad distortion on certain low notes at low volume. I think it cleans up at higher power, doesnt seem like its just being masked by loud volume. Is it possible that my amp Hi-Pass filter is the culprit? I think its in both speakers.

Thanks for the info. Perhaps it would be easier to do some basic layout before cutting.

[@DIYAudioGuy]

Definitely

[@scamchan]

But do it bump doh?

[@DIYAudioGuy]

Stay tuned, we're going to find out!

[@keithmusilli7692]

I think people get confused about low profile subs. Just because they smaller doesn't mean they are for a smaller box. They still need the recommended volume but when you are working with a shallow space, like building a box for inside a wall or one that fits under your bed or couch, these shallow drivers definitely come in handy

[@Boeblabla]

Metric pls

[@NDColorado2023]

That enclosure is roughly .16 cu.ft internal

[@DIYAudioGuy]

Right! Far too small for a 10.

[@tymanG19fan]

Looks like they knocked off plenty of JL audio technology

[@DIYAudioGuy]

So why use JL when this is 1/4th the price?

[@chrishuyler3580]

@@DIYAudioGuy well, for one, JL offers a D8 (dual 8 ohm) version which would better serve my amplifier plans. I could settle for a 4 ohm SVC but I don’t see that getting released by NVX before I get to that stage of the install.

[@tryandtakealaska3797]

lol you forgot to demo the sub in the small box.

[@DIYAudioGuy]

Incorrect. I deliberately did not do that. There's absolutely no need to.

[@alvinpong2374]

Mine is a Rockford fostage shallow mounted subwoofer .... For getting good bass you shoud make it open type' then u will get what u want and much bigger is ur box much quality sound

[@DIYAudioGuy]

By open do you mean ported?

You could add a "that's what she said" about once every 30 seconds in this video.

I was thinking more a "that's what she said" comment, but....

[@DIYAudioGuy]

I was wondering how long it would take before we got one of those.

[@ajc-th5ei]

@@DIYAudioGuy - you can't blame me for pointing out the obvious. I blame you for the setup. lol

[@jigsb9146]

Why not try show us how it sound? Lot people doesn't care about the graph, they care about the sound itself. Maybe next time try the actual sound test

I always assumed the thins are meant to be in fiberglass/ stelth boxes made to fit a specific spot or thin but wide boxes taking up the entire under/ behind area.

[@DIYAudioGuy]

Yep.

[@keithbailey5923]

Thin???????
