Are You Kidding?

This box is just amazing, perfect in every way(for the price)there is NO possible way you can buy a better box at this price(including shipping)! end of story!!!!!

Pretty good and Great Price

Bought this to go along with my Alpine type r and it works great with it.

awesome

im very pleased with the 12'' sub woofer box i order quickly without really doing research on it and im happy i did its perfect and nice fit in my trunk without taking up too much space

Good deal

Good box for a decent price! Just wish I had gotten the dual box instead if single

excellent

Would recomend for anybody. Sounds right and looks good. Made very good

Great box for my type r

Box sounds great with a type r. I have mine wired to 2 ohms on a hifonics Brutus brx 2000.1 with a second battery and zero gauge wire and it sounds amazing

BANGER!!!

Bought this box for a 12" type r that i had in a sealed box. It hits sooo much harder in this box that i will never get a sealed box again. This box has a wider range than my sealed had with much more punch. I have 1 12 running on about 700w rms in a 08 camry and its a lot louder than people in know with 2 12's. The flush sub mount also looks great compared to the cheaper boxes on this site.

pretty good happy with it

I like it. It works for me with this box my one jl hits harder than both ever did with the old box had to take off the trunk latch to make it fit in my 2012 . Mustang

very nice sub box

For a prefab box it is nice, I put a sundown 12 there 600watt woofer, the lows isn't to bad it could be better, but it wasn't built for the woofer specs. Construction is top notch and it looks really nice, I would recommend if your not a bass head, and putting into a nice car. And it fits in my 2013 mustang.

Good

I bought two of the 12 inch type s subs and am happy with them. They arnt the loudest but are worth the money. Great for someone getting into the sub game

Alpine Subs

Worked great in my application, always have had good experience with Alpine products. The dual voice coil configuration makes it easy to order what you need to run your subs at 2 ohms.

Great sub and great price!

Alpine has never let me down. This subwoofer hits extremely hard. I have one powered by an alpine mrv-m500 wired at 4 ohms in a ported box. The amp is only at the normal output power setting and that's all I need. This sub is a great buy for anyone who wants the perfect amount of bass to not drown out the music completely. Don't get me wrong though, this sub is capable of doing that if you want it to.

Perfect Box

This box was suggested to me as a match for my NVX VCW12 and it’s perfect for that sub in my opinion...well built and sturdy

Yeaaaaa!

If u know me I like bass! I have 2 of these in the ground shaker 2 12 sqp
Box and it slams. I was surprised cause that's really nota big box. Imagine
A custom box! Other than that I have it hooked up to a brutis 1200 @ 2 ohms. Good subs.

subs

My boyfriend wanted these subs so i decided to buy them fir him hes happy with them

descent!

This speaker was second choice in regards of finding one that had high temp voice coils. I hooked it up to class d autotek1500d and dropped ohms to 1. I broke it in over three weeks and then as soon as she started banging good, it blew. It had great sound but maybe sealed box and hot summer day banging didn't go well? Either way can't really be mad it was good just not good enough for my application. Vented boxes keep speakers cooler just don't have that tight low I like so if you like sealed set up then get something that can handle the heat!

Best subs around for the price

Started with a 10" alpine type E that is now in my girlfriends toyota celica. Bought 2 of these for my car and they sound amazing no matter what style of music im listening to. I couldnt say enough good things about these subs. Extremely satisfied with all alpime products, especially the type S subs.

It Alright

I have owned two of these both have broken on me. Thee first was my fault and the second was a factory issue but would not honor warrenty. They sounded awesome when they worked. I had only one hooked up at a time in a ported box with a alpine mrv500 amp.

bass shaking, hard hitting, deep low traveling bass by far!!!!!

I had just replaced 4 10" orion cobalt subwoofers in a 5 cubic foot box ported at 45hertz. with a sws12d2 subwoofer in a 1.5 cubic foot L vented wedge box tuned at 35.1 hertz. this thing hits as hard as my old 4 orion 10" and hits as low as the 4 10". for the price of this sws you get more then your money's worth!!! this sub slams hard in my hatch back!!! I've been thinking bout getting a sws15d2. don't get me wrong the 12 is loud n hits low. but im a bass head!!!! to the fullest!!!

excellent budget sub

Great service from the guys at sonic electronix as always. Sub is one of the best bangs for the buck. It sounds great paired with my hifonics amp. I can't imagine how it would sound if I built a tuned box

great sub for the price

The sub works great with my 1200 watt pioneer mono amp, and it thumps hard even when not using 100% of its potential. I would recommend a lower wattage amp, because my amp blows out the sub.

great, pretty sub.

this subwoofer is great on my phoenix gold 300.1 at 1 ohm(makes 340 rms at 2 ohms) and it likes high 30 hz to 45hz. recommend to anyone who appreciates sq and a little bump to make your music come alive.

Great subs

where to began.. i have 2 of theese wired in 2 ohms powered by a ZRX1800.1D in a ported box tuned at 35 and it rocks my trunk i have a 1977 chevy caprice so i want 2 more (trunk is big enuff) and the amp can handle 4(so why not if you wanna B herd for a block or 2.. two of these is all you need

Lotta bass, little money

I ordered 2 of these subs for my senior project and boy, i was definitely not disappointed. I built a sealed box to the manufacturers specs and machined it out on a CNC router machine. Whoever said sealed subs don't hit hard definitely hasn't heard these baby's! You can feel the bass in your chest and there's great response with a sealed box with really tight sound. I wired each subs coils in series, to double impedance then parallel together to cut it in half to bring the final impedance to 2 ohms. Im using the hifonics 2000.1D amp tuned to run at 900w rms. These subs really bump for a great price, all the kids say they hear me coming up the school driveway! if you are looking for an ear piercing bass i would build a ported enclosure because im sure these things would perform great in that scenario too. But 2 of these subs in a sealed box tuned to max potential is perfect for what i wanted for daily driving, cant even see out the rearview! these things perform great in a sealed box and have been running cool, they definitely handle the power efficiently. Alpine all the way! i have been recommending the type s's and type r's to all my friends now, these are some of the crispest subs and the tightest bass ive ever heard. I cant speak to the durability because i've only had them for 2 weeks, but after driving for a while i stopped to check how they were doing and the cone wasnt even warm after bumping for hours at 900w between the 2 subs.

Awesome sub box

Haven't hooked it up yet but quality and construction look excellent. Shipping was super fast. Delivered in 24 hours from the time I ordered. Thanks Sonic Electronix. Will definitely be coming back

Great quality little box!

This is surprisingly better quality than i expected. The size is not that big which is exactly what I was looking for and the carpeted part looks very nice and NOT cheap. The front glossy trim piece looks very nice as well. My JL W3V3 sub fit snug and perfectly in and it sounds deeper and cleaner than my older box for sure. The only thing that I actually was not expecting was that the box did not have wires attached to the terminals inside the box to attach to sub but good thing I had the ones from my old box and I just swapped it out.

Great Box!!!

This box is amazing for the price. It has a nice, sleek faceplate and an eye-catching design that I like. It's also filled with polyfill to cut out the port noise, which makes an awesome sound. The box is a little on the big side so with my Pontiac G5 i had to take out my folding rear seats to put it in my trunk. Even doing that, it was a tight fit getting it in, but once I got it in my trunk it was a perfect fit. It also has a flush mount for your subwoofer. It is a perfect box for my Power Acoustik 2500 MOFO 12inch subwoofer. I would buy again.

By Anthony on June 18, 2020 Verified purchase

Can't beat for the price

The box is well built true spec on MDF. A little smaller than expected but that's ok it's pretty heavy compared to other boxes around the same size. It does not come wired and you will have to find terminals through white polyfill to tear open a slit to run wires. Don't really like the terminals on the back but they work fine. Its a good looking box mine shipped fast and no tears or dents. as others said doesn't hit the really low lows that great but not enough to where id return it. I'm running an r series alpine and it hits HARD for what it is.

Belva ported box

Perfect size fit for my T2 12 sub sounds awesome would recommend solid box.

Great value, decent sound.

Bought this enclosure for a NVX VCW122, it sounds decent, plenty of bass, but crazy amounts of port noise. It would work well in a sedan or coupe, but in a hatchback or wagon, you can hear the port noise in the front of the vehicle. Overall, very clean box, very nice sounding.

By Buck on October 2, 2016 Verified purchase

Solid box!

It looks great and the materials used are of good quality. I have a 12" Kicker CompR in mine and sounds really good!. I would recommend. It is truly a great value for a great product.

Belva Box

Belva ported box works great paired with a Polk 12 and 1500 watt amp in my BMW, it's a bit larger than I expected but sounds great.

Great product

Great box Sturdy comes Insulated look stylish and look perfect for any 12 inch.. if you go with this you would be Satisfied with the box

Well made box

This box is perfect for the price. Durable, heavy, and it comes with filler. Makes my pioneer champion series pound hard. Some people thought i had 2 subs.

Bella BBX112BK

Very nice enclosure. Looks great. Very nice construction. I really like the recessed look where the speaker mounts.

Love it

Purchased this for my NVX VCW122v2 subwoofer. Finally gave up on finding the right sealed box and got this ported box which basically fits the subwoofer like a glove. Good construction, easy to set up, has spade ends for the interior connectors. The exterior connectors are banana or exposed cable. Belva sells a set of banana clips, clipped together by a red plastic clip, excellent, adds a little bit of a professional touch to the install. Get them, they're like $12 and worth every penny. What can I say, its the right box for the install. (Side note) The rubber ring that comes with the NVX subwoofer does not fit under the current piano black faceplate on the box, don't use it, its a headache.

BBX112BK

this enclosure came as a package with a Polk DXi1240DVC, it did really well in my wife's BMW for a little extra bump without stressing the stock speakers. would definitely recommend for the average commuter who wants a little more

By South on August 14, 2020 Verified purchase

Love it!

Nothing much to say, it's a nice looking box. My Rockford Fosgate T1 sounds really good with deep bass..

By Rey on March 9, 2016 Verified purchase

Awesome boxes

I ended up getting the last 2 in stock and I'm glad that I did, they sound really good with the NVX V3

By Stephen on April 29, 2023 Verified purchase

best 12 for the price

I order this sub thinking it be OK till I git a better on but when I built the box for it and got it playing its really loud and clean sounding it sounds good in 1.70 cubic box with 4 in port that a foot long and mount the sub up side down works better btw, but I got told a lot that its loud

By calvin on August 20, 2015 Verified purchase

Great value

Good product low price and fast ship
I love it

Great product

ALPINE is a great product period. Buying a great product at almost half the cost of a retail store makes ur experience even better!

Great sub

For the price, u can't beat this sub. The best bang for your buck

Great Box Overall

I paired this box with the NVX DVC (Dual Voice Coil) 12 inch subwoofer. The box really brings out the bass that the sub is putting out. The box also feels quite sturdy and looks beautiful. I would highly recommend this box, especially if you'll be pairing it with the same subwoofer as mine.

By Adam on May 28, 2024 Verified purchase

Great box

This box is perfect for the NVX VS122 version 3 sub. Sounds and looks great also well built, quality carpeting and terminal posts.

By Dave on May 30, 2025 Verified purchase

Nice box

The only reason I can review this product is a friend has one and it sounds great. I had to return mine due to the size. Be sure to measure before you order. Does not fit 5th gen Camaro SS. Perfect if you have a SUV or a vehicle with a big trunk.

By Aaron on January 15, 2025 Verified purchase

Good quality speaker wire

This is some good wire. I got it for free with the bass package I ordered.
