This box kicks a**!

I have a 15" kicker compR, it works great with this box. Very good quality, cheap in price.

Nice Box

Very well designed Box. The carpet on this box is really nice and the box looks perfect. I have a kicker cvr 15 in this box and it absolutely pounds!! Oh yea and if you have a New body Style(04-08) f-150 it will fit in the space between the passenger seat and the rear seat with the smaller rear seat on the passenger side flipped up and the box will face up.

BELVA 15'' BOX

AWESOME BOX VERY SOLID AND FITS NICELY IN ANY TRUNK WITH ROOM TO SPARE

Couldnt Ask for More!

Purchased this box for my JBL W15GTI MKII. For the amount paid and product received, its a great purchase. Couldn't have built this or have it built locally for even close to the price. Is it as good as a custom ported box? Probably not but that would be subjective but I love the SQ coming from it now. Can't comment on the durability because I've only had the box for about a week but I do not hear any leaks or rattles from the box. Connection pieces are solid. But best part of my experience with this purchase was the customer service given by 'Justin'. Gave me a great deal and got it shipped to my door within the week.... Couldn't ask for more. Would definitely recommend it.

Decent Enclosure

The box works great for my new Polk MM 15". It's a little bigger than the recommended 1.5 cubic ft. but it seemed like it would suffocate in a box that small. At the 50 dollar price point you can't hardly build yourself one for that and this one has quality connectors and it's built solid. Definitely recommend to someone looking for a 15" sealed box. And Sonic was great with shipping and customer service as always.

W/ 15" Kicker

This is a great looking box. Well designed and built. The carpeting looks amazing. It's big, but fits perfectly in my '99 Durango. I figured I would have to remove the 3rd seat when I saw it, but there's actually enough space where it isn't even touching the seat or rear door.

Perfect

Fits very nicely into the back of my '90 Jetta. Could even fit two in the trunk if I crammed them together. Carpeting is very nice and so is the construction quality.

Great box

Great box. I bought this box that is great box, for the value. I really am the shipping was fast also.

good box

i have a 15" kicker comp and it slams. it fits perfectly in my grand am. the carpet is really nice. looks good in the trunk

Belva MDFS15

great price. nice looking box works very well. I have it in the trunk of a mazda protege.

15n sub box

My son loves this box. It is usable in the space he has.

pound that box

you get what you pay for, decent box, no frills, does the job, good construction. should've gotten a ported box though, waaaaayyyyy more sound from a ported box has been my experience, but what do I know, I'm just a consumer :)

Excellent Box

I put a 2000w Quantum Audio subwoofer in this box and it sounds better than ever. My old box was a vented box and can't hold a candle to this one.

The box is of excellent quality. Well built and solid. Very tight and clean carpeting. The pollyfill is well placed as well.

I would definitely recommend this to anyone looknig for a good sealed box for a low price. Can't be beat.

great box

the box is sturdy and good. the price and shipping were really great.

Excellent Box.

This box is a Excellent 15" Enclosure for the Price. Only reason i gave it 4 stars is cause the Wood is kinda cheap but still very strong. Definetly takes a beating from a Orion 15. I would recomend drilling the Screw Holes out. Other wise this wood may chip or Break.

Vented 11.3cft, 320L Sono tube

Testing my first sonotube build on a budget for home theater. Tried the first 9 minutes of Star trek, ITD. Testing with a condenser mic it recorded .8 % of the time between 16 to 27Hz. The box was tuned to 20Hz. Infrasonic filter set to 13Hz so the cone would not surpass it's excursion. It still picked up Hz from 8 to 15. I got in trouble for playing this in my apartment. Lot of audio people say you can't use a car sub for HT. JBL has published data on the specs that is very important to the decision to purchase this sub. Before you buy a sub model it with WinISD and compare. This one comes out on top for the price and performance. The appearance and quality of the sub is excellent.

JBL 15 Inches Woofer

Anyone looking for a four ohms fifteen inches woofer for a car, home or professional audio installation this is a good woofer to install.

Bella enclosure review

Well built for a pre fab box.Under braced like most "bought" boxes.I added 1 inch mdf strips.Comes with stuffing if you're into that.Overall,cheap enough and good enough to slap something together in a pinch for some thump.

Great subwoofer

I have had this sub for about 8 months and have had no problems at all. When i bought it it was only like $130 but now its $199. For what i paid it cant be beat. I also have 2 Memphis PR 15's and this JBL has much better sound quality. But for $200 i would probably buy a Type R. This sub is great though dont get me wrong. I have it in a ported Sonic sub box from this website as well. If it had a bigger box it would sound much better in my opinion.

Also i had about 400 watts going to it with my old amp and i knew it could take more so when i got my new amp i had it hooked up by its self getting about 700-800 watts and it took it well but it was definatly maxing out but no distortion. Great sub JBL

Nice solid box specs are off a little.. Cutout is 14"

Cutout is 14"

Not Cutout Diameter: 14-3/4"

Worked out for me..

Solid Rock-Box!:)

I really like the non-ported enclosures, as they have a crisper bass, but need a little extra juice from the amp.....and when you punch the bass i have had 1/2" MDF enclosures tend to develop rattles in them and these are 3/4" SUPER Solid construction and haven't had 1 problem yet! These are built solid and very clean and neat with the professional carpet finish! Haven't even had the corners start coming loose, and I have 2 of them.
Thanks

good box

product was good sounds nice, i do agree that the carpet could be glued a bit better but i dont care.

Best Bang for the buck...

It has been over a month since the install. They are just now breaking. I use 2 of them in a sealed (1.5 cubic ft per chamber) box. Matched the subs with JBL GTO 700.1 @ 2ohm. Gain is about 3/4 and bass boost less than half way. My ears hurt. They hit so hard the whole car(02 Accord 4dr) shakes so much. I get the great lows which i really wanted. I would recommend this subs to anyone. I do not have any cons so far. I will update my review in 6 months or so.

GREAT PRICE!

Loving this box! Usually, I Order Off eBay but same price-- BETTER MATERIAL & PRODUCT Will Order More Car Audio SOON!

jbl gto1514d

Bought theses a while ago and still hitting hard as b4, nice product, neighbors hear me coming and i only have a 1800watt amp and a 2farad cap...

Great item!

My son wanted this for his SUV. He has been very happy with the sound quality.

Honest review

I received this box free with my sub purchase. I was planning on building a custom vented enclosure. Since it was free I wanted to at least try it out first. I upgraded from a 2 12 cheapo setup in a prefab vented enclosure to a single 15 NVX VCW in this sealed box. I'm still breaking in the sub, but I can tell that this is a great combo. The terminals, carpet, cutout, design, packaging, etc, was very well done. I cant give 5 stars for durability yet, but it looks like it will be good for a long time.

I love this sub

I have had mine for about 2 months now. At first i received the singe voice coil version by mistake but i was able to ship it back fast and no cost to me (thanks sonic!)

But anyway, i running 450 rms to it and i think it could handle at least 500. But even though i have it wired to 2 ohms i measured it with my multi-meter and its reading about 2.8. I know its not going to be exactly 2 ohms but 2.8 seems a bit high to me so im not possitive its getting a full 450 watts rms. But for what it is getting it sounds pretty darn good. My amp is what is limiting it because it clips but im getting a new amp soon so it should be alot louder! I got this on sale but i think it is worth the regular price.
I also have it in the ported Sonic box and although i think it needs to be bigger for better lows, it sounds pretty good.

NVX VCW154 DOES NOT FIT!

The subs basket is too large for the box so I had to make the hole larger to fit the sub. Other than that the box is nice

Nice done!

I got this for my 15 boss. Hit pretty hard together. Awsome box

By Max on April 23, 2020 Verified purchase

Does the job for the price

The box does the job for the price but if you really wanna beat down the block you need to get one of those ported/vented boxes

By Nathan on January 16, 2018 Verified purchase

Early bird gets the worm.

First off. It says JBL right on the dust cap. It's beautiful and massive. I want to give a good review. But I don't have cons. It sounds deep rattles everything that gets in it's way and is not gonna cr*p out anytime soon. Runnin it on a 900 watt pioneer amp and it isn't a power hungry beast. Well my lights dim very badly but it is a fifteen. If you don't love bass please get the 12 of this series. This is for bass heads only.

Awesome box!!!!

Put my new Rockville k6 15’s in boxes and they hitting hard????

Solid construction for price

Clean and solid construction inside and out. Quality materials and fit. Only issue is that the "carpet" is more of a felt-like material that is lightly glued. Good enough for home or car use, probably not for pro use. Totally great for the price.

Great buy! Put together well and everything I was hoping for

Im really happy with this box, would definatly recommend!!! Well built and would buy again

Awesome sub!

I just bought this sub and gotta say it is CRUSHINN! Had some JBL's about 6yrs ago and they were good then and they HIT still. For the price this is a hella deal. I've got in a ported custom box built to make my trunk area flush and its awesome. will definitely buy more of these. awesome product!! A++++

and this company will answer all ur questions about the sub and wiring suggestions. very helpful.

Great Box

It's a great box for a 15 inch subwoofer. I prefer a sealed box for more space in the trunk.

By Jordan on September 22, 2022 Verified purchase

Very Impressed

I recently purchased two of these woofers for use in a small room EDM application. I mounted them in single 1.5 cu. ft. boxes and am running them in series at 8 ohms and have 800 watts of power going to each one. They pound the walls roof and floor quite well. I couldn't imagine how nice they would sound in a car? One would be sufficient, two would probably foam bile up your throat if you where driving a sub compact car! Just make sure you look for the RMS wattage on your amp and don't skimp on power!!!

HOme speaker

These speakers worked great for our in-home system. We did not want anything that would be too loud and these were perfect. Installation was very easy.

Nice sub enclosure

I have two of these in the trunk of my 2015 civic with rockford fosgate p3's

By jeremy on February 28, 2023 Verified purchase

nice subwoofer

I had two of these subwoofers and they really pound. I had them in a sealed enclosures and it was still shaking everything. This is a nice entry level subwoofer. Would reccomend this to anyone that us just getting into car audio.

Sounds good

Has it with hooked up with two 12's. and the JBL 15 is on a 500w amp and sounds great.

Big Bang For The Buck!

I installed my new 15" JBL's in my suburban and can't believe how good they sound on just a 500 watt amp! I can put a lighter out sitting in my front seat and not even turned up halfway. Best deal I've ever found for hard hitting subs.

Great Value

Works Perfect, and for the price I cannot complain. Although had difficulty putting in my trunk (Small trunk), I got it in and made it work!

great stuff

Comes in flat sheets instead of being rolled or folded. Thats a nice benifit. Nice dense n thick backing that sticks very well! Good quality foil is used also. At sonics prices this is hands down best product available.

GOOD PRODUCT

THIS IS A GOOD PRODUCT LOTS OF IT I DID IT IN MY DOORS DID THE PANELS AND THE METAL ON THE OR AS WELL AND IT QUIETED MY CAR DOWN I HAVE A STRAIGHT PIPE AND I WANNA HEAR MY MUSIC MORE AND I CAN IT FEELS LIKE I AM SITTING BETWEEN 2 5 INCH STEEL DOORS IT INCREASED THEIR DENSITY AND INTEGRITY STICKS GOOD JUST CLEAN BEFORE YOU STICK BUT DUH THAT IS COMMON SCENCE ALSO A TIP COVER HE BACK OF THE SPEAKER BASKET ASMUCH AS YOU CAN THAT MAKES IT SO ALL THE SONDGOES FORWARD INTO THE CAR INSTEAD OF THE PANEL

good subs

These subs pound Hard! I have 2 of theses wired to 1ohm on an Lanzar Opti2000D and planning on wiring all 4 into .05 ohms... Will post the results at a later date.

Very good

Was able to use as a basic starter kit for an 09 Elantra; did the top & side of the trunk lid and both front doors including around the speaker hole. I noticed a slightly quitter ride and the stock speakers really do benefit from the stiffening sheet metal. The midrange is clearer and bass is more robust. The paper backing can be a pain to remove at times; the butyl rubber often peeled with the paper and I had to use my fingernails to pry the two apart, but not a huge deal.

Great product at a great price.

I have this Maxxlink installed in my scion Xb with dynamat as well. I used Dynamat as the first layer (32 sq. ft) and was pleased. I am rebuilding my system for 2 18 subs with 6 8s and tweeters so I wanted some extra reinforcement. For this amount dynamat cost almost double what I payed for maxxlink, and given some good reviews I figured id give it a try. The two materials, aside from the branding on them look and feel identical. Sticks great and is very easy to use, I now have 3 layers and NOOOO rattle. Even if all you have is a sub or two in the trunk, lay some of this down in there first, you will notice the different. More bass and clarity, less rattle and so simple anyone can install it. Definitely recommended by me.

wanging subs

i got two of these on a belva bb3000d at one ohm. custom made bandpass box in a astrovan. these things flex my van like crazy. excellent sub for the money. they pound in a two cube sealed box as well.jbls documentation that comes with the subs is first class. you get speaker gasket as well. a classy sticker and great build quality. i would like to get 4 of the svc subs for that all out basshead groundpounder.

A nother Quiet ride

Recieved purchase in timely manner like I always do from Sonic
Maxxlink vsd-tk is a great choice for a DIY looking to quiet down there rattles an it almost eliminated all my road noises too
Great product!! But adds a lot of extra weight to your car!!!
Will be buying all my electronics from sonic!!!!!!! Thankx

GREAT STUFF

my observations are
1)the box was deceivingly heavy for it's size.
2)when i first opened the box i was surprised that there was very little, if any odor.
3)butyl layer on this stuff was at least twice as thick as my trusty peal and seal
4) foil was also substantially more beefy than peal and seal
5) you can hold a sheet straight out and it would not sag
6) despite being rigid, it was incredibly easy to cut and roll on with great adhesion

did doors with a little over 40% coverage you could hear a huge difference using the infallible scientific knock test. I have a bunch left so deciding between doing my floor boards (quiet cabin) or the the trunk. i give this stuff two thumbs up .if you can get this on sale buy as much as you can, then buy some for your friend. great stuff even at regular price though.

Perfect

As good as others that cost more. Great value , no smell , sticks awesome. Looks good too. I have over 100 lbs of it in my jeep. It's 17 pounds for every 20 square foot. Nice n dense.

JBL 15"

I purchased two of these JBL 15"s over a month ago and when I first bought them I was worried they wouldn't hit as hard as I would like them to. With buying brand new speakers you have to give them time to break in or losen up if you will. I also purchased a 5000 watt planet audio amp. It's only been a month and I'm still tuning my system. Long story short 5000 watts on two of these bad boys shakes other cars at red lights & my amp isn't even half way turned up. If your looking for a lot of slam in your vehicle I recommend buying two of these and matching the wattage. 5000 watts is plenty but remember! You tune them at your own risk.they take some time to break in. All in all. Great buy! I highly recommend these speakers! Thanks sonic electronix!

Crisp and Clean

These subs are amazing for the price. I purchased both for under $200.00 and it has been so well worth it. They are very accurate for a 15" subwoofer and the deeper the bass goes, the richer it sounds. I'm a bass head from the 80s and 90s so I take it back often and these subs play the music from those decades superbly.

I really don't have any cons other than me being petty... I prefer the inverted dust cover look but even with that, it looks rugged as constructed. I have been impressed since I installed them otherwise. I used a prefab sealed enclosure that I got from a buddy and changed the front mounting plate from 5/8" to 3/4" MDF. It's slightly larger than the recommended 1.75 cu^ft at 2.03 cu^ft. I also resealed it to ensure there were no leaks and THESE SUBS A MONSTER!!! You definitely know they're not competition subs but for $200.00, I'd bet they'll perform, at a minimum, as good or better than any other budget subwoofer on the market. 350w RMS is all you need to make them move and I tried a Pioneer GM-D9601 and an older Rockford Fosgate R1200-1D and both keep the subs pounding hard. I prefer the RF over the Pioneer because they seem to hit just a little more solid and carry the rich deep bass tones a little smoother and louder. I'm also going to get an AudioPipe APCL-18001D just because I'm impressed by the dyno vids on YouTube. This amp is very similar to the 1514D's in that it's underrated for the amount of $$$ you can obtain it for. All in all, buy these subwoofers without hesitation unless you're competing.

the best

I own JBL but this is the best ever very very clean bass five star product

*UPDATE: More Results*

I apologize for taking up the extra space to post my *UPDATE* but I don't know if editing a previous post is possible on this website. In the automobile industry, I've often heard that there's no replacement for displacement. I tend to believe that for the most part and leaving room for the exceptions to that rule. My results are like a gradual progression in displacement; from 4 cylinder turbo to V6 Twin Turbo to V8 Supercharged MONSTA!

4 cylinder turbo - My initial sub setup was the sealed roughly 2 cu^ft enclosure I spoke of in my first post. It had excellent sound quality and very rich bass notes. What it lacked was those deeper freq's along with volume.

V6 twin turbo - I'd had a pair of Hollywood Sound Labs 12" DVC subs in an "Isobaric Single Reflex Bandpass Enclosure" (try saying that 10 times real fast) from 1992 until they were stolen in 1997. I remembered how low it sounded and it was very loud (to me) so I built a similar enclosure using my GTO1514Ds; 1.6 cu^ft sealed chamber with 3.5 cu^ft on the ported side and a 4" round port (simple and easy). The result? Much deeper bass with a considerable gain in volume at those lower freq's but being an "ole skool" basshead, I wanted just a little bit more volume. My first thought was to get different brand of subs like Dayton Audio's Ultimax UM15-22 dual 2 ohm subs or a pair of Sundown Audio SA-15s. My pockets aren't deep so much research persuaded me to try a simple ported enclosure. I'd had ZERO experience with one until my next venture.

Supercharged V8 MONSTA!!! - I built a 7.4 cu^ft ported enclosure with a 4" round port (simple and easy). There's no "divider" but I did use some 1X1X36 plywood studs to brace it. Talk about a difference maker... BANG, BOOM, DROP BOTTOM, HIT, SLAM... Insert whatever colloquialism (slang) term of your choosing and they do it! I've got the bottom end I was looking for and it is LOUD! I may rebuild it later and incorporate a slotted vent/port as opposed to the round port that's in it now but only for aesthetics.

For $195.00 with the special Sonic Electronix is running on these subs, this is a steal in my book! Since I'm an "ole skool basshead," I'm taking it back to my high school days with 2 Live Crew, Run DMC, Robert Plant, Beastie Boys, Information Society, etc, all of which are setting off car alarms and pissing off traffic every now and then. You won't go wrong with these unless you're in serious competitions or you simply want to lose your hearing soon. Great subs at an unbelievable price. Buy with confidence and satisfaction.
