OK wire if you like red wire

I received this wire because when I bought my Image Dynamics speakers from Sonic the description said it included speaker wire in the box, but when I received them there was none. I called Sonic and they sent this wire to make up for the error. I later called Image Dynamics and found out that they no longer include speaker wire with their speakers so Sonic if you are reading this you can update your description and pictures on the ID speakers to NOT show speaker wire. For the record I bought the Image Dynamics CTX65cs and the CTX4 speaker sets. Great speakers by the way. Thanks Sonic for all your great products and sound advice, no pun intended:)

nice sound

very good product at a pretty good price lowest i could find on net and sounds good

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.

Use to purchase this all the time

Belva brand is good affordable material when starting out but through out time cca corrodes if you have the money buy ofc cable

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 extra fine wire

This is excellent speaker wire. One wire has round insulation while the other has square insulation making it easy to identify hot and grounds. My only installation problem was I didn't order enough. I needed a quantity of 2 just to wire a single cab pickup.

Good wire

This wire is great speaker wire. I like the way it looks and works great.

Excellent value

The speaker wire is a good price for the length and gauge.

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

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.

Awesome subs

These things are awesome I have 2 of them running off a kicker kx1600.1 @ 2ohms and it's super loud I would definilty recommend them.

Belva ported box

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

Simply WOW

If you want real ground shaking, hard hitting power then look no further. This is all you need. I would highly recommend this sub if you want clear loud sound. I currently have 2 12s and you can hear me coming blocks away

By NUNO on November 16, 2017 Verified purchase

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.

By Alejandro on July 22, 2016 Verified purchase

By Brian on June 17, 2020 Verified purchase

Just what I wanted!

Upgraded from a P3 to the new Type-R because i wanted more rms watts with my Alpine mono amp and am blown away by the difference! Got 1 12 running at 1ohm and it sounds like 2 12's in my trunk. 100% satisfied!

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 value

It work awesome I would buy a hundred more if I had to.

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..

I love the sound and the reliability! Simply put it beats!

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

Awesome deal!!!

Awesome sub!!!!! This is the best 250$ and under sub you will get promise!!! I've been into car audio for 25+ years @ this pounds!! And I ran 4k true power to it and it never even started to smell! lol I feel bad that I cant give 11 stars!

Great sub

I got this sub when I realized I ordered the wrong one but I can’t even complain. The bass this thing puts out is insane, normally I run 2 10s but just this single sub in a ported box is perfect. Couldn’t be happier

By Patrick on August 29, 2018 Verified purchase

Blows anything else in this price category out of the water.

Bought this to replace my 1 year old Type S. My daily driver is a 2007 Chrysler Town and Country (Hey I got kids and they haul crap). I just wanted a little more than what the S was giving me. Got way more than I had hoped for. I thought I would get about double the sound. Nope its way more than double. I have this matched to a Pioneer GM D8601. Puts out (True) 800RMS @ 1ohm. Installed it today and got it set up. I dont do the break in ritual some people live by but I do take it easy for the first hour. Then retune and go all out. I must say for 1 12 in a 1.5cuft slot port in the back of a minivan sounds like I got way more than what I do have. Got a buddy at work work running 2 12' JL W3s and I cant wait to run the db meter with him to see how this compares. I know vehicle makes a difference and box but hes got those in a Tahoe in slot ports and they dont hit as hard. So heres my Pros and Cons....
Pros:
Way under priced (For what it is should really be in the 350+ range)
Very well built
Love the new look
Packaging is solid
Puts out way more than expected
Comes with jumpers

Cons:
Only 1 The included jumper wires.
I run 8ga speaker wire. Why? Mostly because I can, but I do notice a difference in responsiveness and also amp runs way cooler. But that being said the included jumpers have cheap banana ends on them. When I put the 8ga into the push terminals it makes the banana only go half way in. Was a little worried about them popping out so ended up using the set that I had from my type S that seemed a bit sturdier. Plan to rework inside the box and just make my own jumpers to eliminate the potential problem.

Alpine R12D2 Subwoofers

These subs are monsters unreal bang for the buck! I am running them on a JL1000 mono block amp and all I can say Is ouch!! They hit so hard in a spl ported box 1.71 cubic ft of ported air space hits harder than 2 15’s!!! I highly recommend these subs if you want shock and awgh thunderous BASS

Good Performance

750 Watts ... 15 Hour break in ... Clean Deep Bass. Ported 1.86 cubic feet

Alpine R-W12D2

Perhaps because I’m an old school “system” having guy (had systems back in the late 1980s and Alpine was always the go. Remember “....and let the Alpine blast!”
Anyways these subs hit!!! Love em

WOW

I got a pair of these Alpine R-W12 to replace my old Alpine type S12. If I would have known how loud they are I would have just got one. They pound and can handle the watts.

WOULDNT PAY $50

Heart Broken. Flutters like Garbage with no Low End Bass.
Buy Anything Else.

Fantastic Subs!!!!

I have had these subs for over a year now and they still bump! I am running 2 12WD4 in a custom ported box running 1800W RMS to both of them at 1ohm with 1G oxygen-free wire and a big 3 upgrade. With this set up my windshield flexes like crazy and the truck sounds like it wants to fall off when I push them to their full potential. You tune them right and they will go off! Absolutely worth the price!!!

Great sub

I owned alpine type R 12 inch sub before but the older model one sub never let me down great quality sub for your money... but I purchased the new were model alpine type R 12 inch sub and I’m loving every minute of it sounds great hits hard.

Def hard hitting and extremely well built

I have owned two of the type s series years back and good grief they were loud, or so I thought, they cracked the glass on the hatch of the 89 mustang they were in. Fast forward to now and I currently have two 2ohm type R. Pushed by a rockford fosgate t-1000bdcp amp. They shake my seats, the roof of my car flexes. With the amps constant power technology at 2 ohm I'm feeding both speakers just a hair under their rated rms. They get as low as the box and amp will let them and when the highs come in (100ish hz)
It sounds like there's a really pissed beast trying to rip its way out of my trunk. They're FANTASTIC subs. I beat on them every single day for at least an hr of full rms pounding. To the point that get a bit smelly. Yet every day they sound amazing. I paid $350 each so seeing them for so cheap here makes me think about adding a couple more to the mix. You will not be disapointed with this sub. I can promise you that. They're built for abuse....

Awsome subs

Went from 2 old 500rms type r subs to these and the difference is huge! These are a lot louder and just seem to hit every note better!

Alpine R series is one of the best ever made

I'll be honest and say that I don't have this current model, I have the one from ten years ago called the 1223D and it's been put through years of abuse and is still going strong. It only has 600w rms compared to this new one but I currently have it wired down to 1ohm hooked up to a Pioneer GM-8701 thrown into a ported box in the cab of my Ranger. It pounds just as hard as the day I got it in 2010. I want to upgrade to this new one since it has 150w rms more and my amp has 800w rms at 1ohm but this old type r won't die! If you want something that has deep bass and longevity all for a great price? This is the one.

Alpine R-W12D2

12' sub amazing sound quality. I loved it.

By Patricia on July 25, 2020 Verified purchase

Excellent

Pounds. Wired to 1ohm in ported box, country sounds good, rock sounds good and it splashes water out of cups with rap, can't go wrong with this speaker.

Great price

Great price on these powerful speakers! Shipping was fast and packaging excellent. Cant wait to fire them up!!

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.
