Customer Ratings & Reviews

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

Just as advertised !!!

I have this hooked up to a Hifonics 1100.1 d Brutus amp pushing 1000 rms and it beats the block hard!! Hits incredible lows and all around great sound! Great price and fast shipping sonic is the best!!!!

Belva MDFS15

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

Amazing Subwoofer

Has a very good feel and structure very solid. Large cone area much better than average stitching and craftsmanship. Mine sounded amazing squeezed the trunk of a VW Golf but you will be heard, Make sure you give it accurate power because of that new motor rating wattage requirements I had mine going for 7 months at around 1200 watts and finally the voice coil was shot.

Amazing Deal! So Far So Good

I bought this sub to install in a friend's car. I bought it with the free ported sub box deal for a fantastic price (Although it didnt fit in the box so I had to sand it down by about 1/2") Regardless this thing suggests about 900 Watts RMS in a ported box (I ran it off of a Rockford Fosgate 750-1D). Sound clarity is amazing and it gets some seriously crushing lows. Its almost as loud as my 2 15" Kicker CVR's in just one woofer! Overall great sub, i would definitely recommend it!

Best deal on the net

I put on of these 15's in a ported box hooked up to a Hifonics 1000 watt RMS amp and WOW! I have used Sounstream, JL, FI Audio, Ascendant Audio, and a bunch others and this is right up at the top. You will not find a better deal anywhere, period.

WOW

Wow is all i can say this thing is a monster, best bang for your buck (pun intended). I have this running on a my audio 1800 watt amp at 1 ohm and it slams.

loud sub

i bought this sub with a ground shaker box and a cerwin vega stroker 1,000 watt amp. this sub sounds amazing and is really loud. it shakes my whole car and flexes my headliner alot. if you want a great sub and have awsome sound quality buy this sub.

Best sub I've had

I have this sub running at 1 ohm on a BRX1100.1D mono block

Sub says it's rated at 850-1000 watts rms
But nvx undertakes their speakers so in sure it can handle more cuz mine BANGS and no clipping or distortion
ALSO I have it on a ported box which this sub recommends using a ported/vented box

Unbelievable

I have this sub running at 1 ohms with my Re audio monoblock 1500 amplifier and its the cleanest most powerful sub I've ever heard. I highly recommend it.

15n sub box

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

Best subwoofer I have ever owned.

I install car audio and have for the last 13 years, this sub surprised me in the best of ways. It looks amazing and sounds even better, I have turned everyone that hears it into a NVX consumer. I have one in a custom 2.4 cu ft ported box tuned to 40 hz and my SUV flexes everywhere lol. SQ and SPL is unmatched oh and it is taking over 1000 watts like a champ! Give it good clean power and you will be living in your car lol. Buy NVX and support the next big thing to happen to the mobile electronics world before they realize I would have paid 400 for this sub haha. Amazing amazing amazing.

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.

NVX VCW152 - 5 star

Because of budget issues it will take a very long time to finish my orders & I intend to order every item before beginning the install so I don't have to redo anything, hopefully. The NVX VCW152 is everything as described at sonic and at a extremely good value, especially with a free tuned box. It does have a heavy triple stacked magnet with a rubber magnet wrap as in most high grade subwoofers. To leave this review I have to guess on durability. I give it a 4 star only because there is no re cone kit but for the price I'm not complaining. I'd avoid cheaper subs that hide the magnet.

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.

By Anonymous on September 16, 2019 Verified purchase

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.

GREAT PRICE!

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

By Claude on May 27, 2020 Verified purchase

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.

By Chris on February 25, 2016 Verified purchase

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

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

By Brock on May 7, 2020 Verified purchase

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

Best triple stacked magnets

This 20mm Xmax triple-stacked magnets 4ohm beast from Sonic made by NVX-VCW154 subwoofers are better than my Memphis M3 15's hands down, better priced also, more rmsw and it's proven to hold it's own against 300oz magnet @195oz this motor can handle 1,500 rms watts easily for around $200 worth every penny, I had to buy another one so not even 4 month later! Wish it had 8gauge inserts, little small, but still 100% love!

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

Sounds great

This subwoofer speaker is awesome. No distortion and voice coil does not bottom out like cheaper speakers. This sub is built very well and the price will not break the bank. Produces all the lows just like a sub should.

By Ferroll on April 20, 2018 Verified purchase

Simply Awesome Bass!

I just have to say that I am very impressed with this sub. I've been running it for about 3 weeks now and it sounds better every time i listen to it. This hits harder with better quality than any other subs i have owned for less money. It is also very efficient.

Only heads up I would give is that while all the manuals and info I could find online recommend a 2.5 cuft box tuned to 33 Hz, the actual manual that came with it recommends a 3 cuft box tuned to 34 Hz. It sounded good in 2.5 but it sounds amazing in 3 with some poly-fil. Not a detractor just something to keep in mind while looking at your available box space.

By Michael on October 15, 2015 Verified purchase

Awesome review

It's completely surpassed my expectations also Sonic electronic is a great site I'll be getting more stuff very soon

This thing pounds!!

Just got this sub recently. Its on a Rockford R1200 amp in a custom enclosure that's to NVX optimal specs. 2.75cu ft ported tuned to 32hz. I made it out if 3/4" Birch with a 1.5" baffle. I tuned the amp with an oscilloscope using a -7.5db 40hz tone. This single sub is ignorant loud. I'll say it again. Ignorant loud. Sounds absolutely great! Very pleased.

awesome sub

5/8/16. First I like to say sonic gave me an excellent deal on this sub, thanks sonic. OK not sure if sub break in is a myth or not but I went easy on mine for 2 weeks, at 4 ohms around 400 watts. Its sounded great, hit harder then my 12 cerwin Vega vmax did at 2 ohms around 600 watts. After break in I hooked it up at 1 ohm around 800 watts, let me tell you this sub slams. It made my rear view mirror fall off after a couple songs, lol. Just what I wanted, ridiculous, over the top bass that has people saying, "why". I'm sold on nvx. Im only running 1 sub because this thing needs lots of power and I didn't want to get all crazy with my electrical system. 1 is all I need or can handle because it pounds. Overall I'm extremely satisfied with this sub. Only had it for a couple weeks so can't talk about durability but it seems very well made

By Richard on May 9, 2016 Verified purchase

Damn good Sub.

This Sub does what a 15" is supposed to do. But you get the punchy bass that you get from a 10" Sub. It makes 03 accord sedan Flex. And I'm only pushing 750 RMS to the sub.

By Alberto on November 24, 2015 Verified purchase

Great subwoofer

I had this NVX 15” on a 1200.1 JG and it was ok. Than a change amp to an 1500.1XTR and the sub woke up. Been using it for quite some time now. No problems at all. Highly recommend

NVX VCW152

They sound real good and hit real hard. I built a wall in my car and have them hooked up to 1500watts.

By Anonymous on May 11, 2018 Verified purchase

Best woofer for the money!

I looked online forever for good 1000 w subs and for the money you just can't beat it the quality alone I would expect to pay 300 but the price is not to say it's sub par but rather a monster sub that puts out some serious sound and moves quite a bit of air! Can't wait to get another and another and one more even!!!

By Andrew on January 9, 2017 Verified purchase

NVX

Extremely happy with NVX I own a 10" and a 15" It sound very clean. The price is very nice tool

Kicker fan, but...

This thing is a gorilla... Sounds like more than one. I need to upgrade my box because it can't handle it. My "3000" watt Autotek MM3020.1D can't feed it enough.

By Michael on April 6, 2021 Verified purchase

NVX VCW152

Wow what can I say, these things for the money are hands down some of the best budget gems out there. A wall of these can choke you out, moving so much air. I would highly recommend these to anyone on a small budget that still wants to get loud and sound decent doing it. Pro’s : high DB’s Price, Looks I like the look especially inverted you want know it ain’t a $500 dollar sub. Cons: only sound quality but it’s not a sq sub per day although it does sound decenct.

Sounds superb!!!

I have my nix 15 d2 in a 4.25 cubic ft box with a 4 inch slot port tuned to 35 hz and I'm able to play all types of music highs lows etc...

Great sub

Would recommend this sub it hits really hard makes my element shake hard

By Kevin on April 4, 2021 Verified purchase

Awesome!

This thing is impressive even at first sight! Great value for the price especially at the sale price of $160... It's very impressive sounds great even new n tight it should sound exceptional once the suspension breaks in. It was this or a Soundstream T5 but I just had a feeling it was better than the T5 plus the T5 was rated at 1300rms but I assumed the VC was more accurately rated 1000 vs many an inflated T5s rating. Yes that logo on the T5 almost got me an truthfully if the T5 had a big beautiful motor hanging out I'd probably got it but that cheesy plastic cover on the motor was a huge turn-off, not only does look awful just gave the sense of cheapness that I couldn't shake so I think the VC was better choice. I'd say the VSW is maybe a better choice for awsome potentially better SQ with less power level requirements for music like rock or r&b but bigger power needs for rap the VC is the only way to go.

By Aaron on February 4, 2020 Verified purchase

I’m pretty impressed

I’m pretty impressed with this. Got it wired down to 1 ohm and with a hifonics Brutus. let me tell ya this thing hits pretty hard. Got a 3 cubic ft box L ported tuned to 32 hz. I think a bigger box would make it a bit more happy. But it Hits the highs really well and the lows are great. But in the end ya get what you pay for it’s a cheaper sub and can’t expect a ton outa it. I deff like my earthquake subzero 12in better. Sounded way better and moved a ton more air. But it was also twice the price. If your looking for a decent sub for a cheaper price give it a shot. I’m not disappointed in it. Deff worth the money.

Nvx vcw152 are amazing

I run 8 nvx vcw152 on 10k and they take it all day!!! Amazing buy would recommend to everyone who wants a entry level sub!

By Bassblazer on February 28, 2018 Verified purchase

Best for the Price

I highly recommend buying this sub. Fantastic built quality. I have compared many brands and NVX sells some of the best products for the price.

By Squirrel4 on November 20, 2016 Verified purchase

Hard hitter

Got this as a replacement sub and have never been happier! It is amazing hits the lows like crazy and all around great sound I have this running 1100 runs and it handles it fine! I would reccomend this sub to anyone looking to turn some heads and a great price! Sonic is the best!!!

By Ryan on November 2, 2015 Verified purchase

Beastly looking

Just got 2 of these monsters in they are a huge upgrade from the vsw 12s I had. Can’t wait til my 7 cuft box is finished. Update these things smash the lows. I’m going to run 4 in a 14 cuft box.

By Clarence on March 27, 2025 Verified purchase

Excellent sound quality

I LOVE nvx. Ive had this sub in 10, 12 and now this 15. Excellent sound quality but still gets down. I built the box to the exact specs, 3 feet, 45 inches of port, tuned at 33hz. Sounds absolute amazing. I keep coming back to NVX subs. Thank u

This is a pretty serious woofer with an entry level price. Performance on par with big brand name subs that cost twice as much.

By Kevin on May 16, 2025 Verified purchase

I love how clear and clean the bass is, and the amount of bass produced from this single woofer is nuts. 10/10.
