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
