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.
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.

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. |

As expected
Could have a better way to decide which wire to use as positive or negative. Only has spaced print on one wire.

Pretty well made box. The sub hole was a little too small for my 12" hcca but a little cutting solved that. I didn't have time to make my own box so this suited me realyl well.

Very nice box. The carpet is nice and seems to be glued properly, although it does look like it might rub off in time. Build quality is very nice, feels very sturdy. There are some globs of dried glue on the exterior but nothing I can't get over. It would have been nice to not have the sub cutout so close to the port but that's just nitpicking. Doesn't come with wires internally but the terminals are much nicer than I've seen on other prefab boxes.
Regardless of what Belva has published, this box is not 1.8 ft.
The gross volume is 1.97 ft, but after taking into account port displacement, it's net volume is 1.30 ft. It's also tuned to 34.4 Hz. Determined using the Torres Speaker Box Calculator.

found this helpful.well built box
For the price it cannot be beat. This box meets the recommended size enclosure for the single sub i ordered, which is the Rockford P2D4. Ported to trick the sub its in a bigger box with poly fill lining. Well built and carpeted in dark gray. I highly recommend it. Hits lows hard and loud.

found this helpful.Not bad
So I bought one of the "Sonic Boxes" a couple years back and it was similar to this box but gray. The sonic box was better build quality. This box has a hole cut that is nowhere near center. It's up and to the right a bit, but that's what you get for a 55 dollar box I guess. The carpet around the ported has started to come unglued and the box hasn't had any play time what so ever. It seems to be mdf and 3/4". The dimensions are correct. Port tune is around 35 hz and net box size is around 1.4 cubic ft. The poly fill probably needs to be glued down so I will stay inside the box. The port used to be rounded on the inside with the sonic box now it is not. It is a good box to get by on since it is built pretty well, but I would recommend getting a box built to spec for the woofer you have for optimal sound. For 55 bucks it's not a bad way to get by, just don't expect the best for that price point.

found this helpful.Worth the space
I downgraded from a much larger box to this one and noticed no difference. Saved me some space, though it's still pretty big, and handles the sub perfectly. Feels sturdy and looks good.
