Belva Subwoofer Boxes with Polyfill and 3/4-inch MDF

Built for Bass

You've got an awesome subwoofer there, pal. But where's it gonna go? You can't just throw that thing in the trunk and call it a day. Don't worry, Belva's got your back. With superior construction, great features and everything you need for bass, you'll be ready to pass up that entry-level box you've been eyeballing.

Belva Subwoofer Boxes are CARB Phase 2 Compliant

You get quality boxes with solid 3/4" MDF because nothing else will do the job right. You want to flex your windshield, not your box's innards. You get polyfill built into the box, making sure your subs perform perfectly. On top of that, you get a box that's CARB Phase 2 Compliant, meaning your box won't emit as much nasty formaldehyde as the competition. Better for your bass and better for you.

Belva MDF 3/4-inch Thickness

Look, nobody buys a subwoofer and says, 'Aw man, I just want a teeny bit of thump.' Naw man, you want something that kicks you in the chest, but you need a box that's gonna put up with it. That's where Belva comes in. While other brands use less-than-optimal 1/2-inch MDF, we've got 3/4-inch MDF to make sure you get all the bass you can handle. Why risk a busted box? Belva's the obvious choice when it comes to giving your sub a good home and giving you the low end you're looking for.

Belva MDF 3/4-inch Thickness

General Features:

  • Single Sealed 10" Enclosure
  • Internal box volume: 1.2 cubic ft
  • High Quality 3/4" MDF Construction
  • Durable black carpeting
  • Pre-lined with Poly-Fil
  • Seams are fully caulked for better efficiency
  • Gold post terminals for clean and easy wiring access
  • Box Dimensions: 14-1/4"L x 17-7/16"D x 12-7/16"H
  • 30 Day return policy

almost perfect

This box is exactly as it should be, connectors are good. But there was a large chip in the box when I got it. Looks like it had been dropped. Not sure where in the process this could have happened. But it is still sealed and works. If it did not have the chip, would be 5 stars.

Fantastic product

This box sounds, looks, and hooks up great don't hesitate ! It's holding a PPI 10 at 700 RMS and holds up extremely well no modification required.

quality and economy

I like to make my own speaker boxes. However, it is quite time consuming to make a good one. That's why this is such a good product. It combines quality and economy of time and money.

Great box for the price

The carpet is kinda cheap and thin but I planned on recovering the box to match the rest of my trunk, making this a none issue. The important part was that the box is very well built, solid as a rock, and has the airspace for my cvr10.

sounds great

I'm using this box with a cvr 10 (http://www.sonicelectronix.com/item_21882_Kicker-CVR102-10CVR102.html) because it was a little larger than the minimum recommended volume for my sub . It hits and is clean. I recommend getting it it's basically the same price/cheaper than building one yourself.

Only thing you need is some spray glue to reattach the polyfill you fold back to run the speaker wire from the terminal inside of the box.

I'm impressed, can't beat this box

I recently purchased this box to put a 10" Audiobahn AW-1051T (DVC 4Ohm; 800 peak watts, 300rms) sub in and this box has made my bass ridiculous. I drive a Hyundai Tiburon and coming home from work today the bass was hitting so hard it was tickling the bottoms of my feet. Now that means you've got some vibrations happening. I can't testify for the long term but from initial review you can't go wrong, especially at this price. I would definitely recommend to someone who doesn't want to lose a lot of trunk space for a huge box, but still wants great sound.

Solid Box, Hole too small for RE Audio SEX10D4

I bought this box for my RE Audio SEX10D4 and the opening was 1/16th too small for the sub. I had to break out the jig saw and trim it all around which was a dusty mess and annoying. Besides having to customize the box to actually fit my sub it is a nice box and great for the price. I am sure it will fit cheaper smaller subs just fine.

Good Box

Got this with a combo with a Kicker 10" and it's the perfect size for my trunk. It fits in the back corner and almost takes up no space.
