  • This box should cost more! It's truly exactly what I wanted and needed
Size: Dual 12" Sealed
I have two JL Audio 12W6 v3 subs. I had them in a ported box, but due to the variety of the music I listen to, the ported box was way too "boomy." It hit hard, but since no one masters tracks at similar balance and volumes, some tracks would sound really great, then another would have so much base, I was constantly adjusting the bass control on my Fosgate T1500.1. I mean the boom was strong enough to break my rear view mirror from the windshield three times, with the last time taking the glass with it. Enter the idea of a sealed box. While I get less vehicles shaking bass, I get considerably clearer thumps from the kick drums in metal, to a great clear boom from rap and hip hop. This box is very well constructed, the perfect size, packages really well, and arrived a week and a half earlier than projected. I got it in three days rather than the two weeks quoted. IF you want or need a nice compact box, and your subs need about 1.1 cubic feet of air space per sub, this is the box you need. With the displacement of the sub considered of course. Keep in mind, you do lose about 10Hz in the low end going to a sealed box, but boy it's made a world of a difference. ... show more

  • Couldn’t ask for more.
Size: Dual 12" Sealed
I’ve always been skeptical when looking at belva products. They make super budget oriented equipment that made me second guess buying them. Looking at this product, I kinda just said “screw it” and decided to buy it. I purchased this for a home theater project. This enclosure houses 2 Rockville 12 inch pro audio subs. Honestly. I couldn’t ask for more. I was very surprised by the build quality. It’s made of sturdy 3/4 inch mdf that is *completely covered* by black carpet. In the past I’ve had cheap enclosures have spots where the wood shows through the cheap carpet job. It’s filled with poly fill and have nice terminals too! I’m very impressed. Good job belva. ... show more

  • Overall satisfied with the product
Size: Dual 12" Sealed
I put 2 12” Comp Rs and the box is very well made and it does sound great! I do think that if it had just a little more air space per side that I could get a little better sound from the box. I’m not a fan of ported boxes and just prefer the sound of the sealed enclosure the bass is much tighter in a sealed enclosure. I just wish it was a little bigger box. But well satisfied with the box and it’s overall quality and the look is great as well. Thank you very much Linton Taylor. ... show more

  • Best prefab box I've seen in 25+ yrs
Size: Dual 12" Sealed
Almost perfect. Great value! Gotta say, this is possibly the 1st prefab box I've purchased that didn't require lots of work to make perfect. I didn't "need" to caulk the joints, as they were all pretty well glued, but I already had my caulking tube loaded up, so I sealed it extra tight to be safe. Two Infinity Kappa 1200Ws in this box sound FANTASTIC. The specs claim 1.23 cu ft per side, but the interior measures 12.5x12.5x12.5 (which comes out to 1.13 cu ft, almost PERFECT for the Kappa 1200w). Do note, the hole for a Kappa 1200w is slightly larger than standard, but I was able to fit the speakers with minimal effort and a little trimming of the holes. Overall appearance is TOP NOTCH, aside from the metal logo on the box. Would DEFINITELY recommend to anyone looking for a good prefab sealed enclosure. ... show more

  • GREAT QUALITY BOX AT A LOW PRICE!
Size: Dual 12" Sealed
I purchased the dual 12" sealed enclosure for my daughters Jeep Wrangler and installed 2 Rockford Fosgate P3 subwoofers in it. Powered by a Punch 1000x1d amp it sounded phenomenal! I was very surprised to see how well it was constructed. Built with 3/4 inch MDF all the way round, and lined with polyfilm. The carpet was nice and tight and seemed high quality. I use to build custom subwoofer boxes when I was a teen and have even been to some of the competitions in the IASCA circuit. This box is no joke, and if you can't build your own then I recommend this box, especially for the great price! ... show more

  • Good box
Size: Dual 12" Sealed
Mine did not come with any polyfil. The connections inside are cheap. The overall box build is nice and sq is good. Mine also arrived with a damaged corner but I’m not sending it back over these issues.
