Single 12" Vented MDF Subwoofer Enclosure (Belva 1SV12B)

12-inch Vented Car Sub Box Made with 3/4" MDF and lined w/ Polyfil (1.8 cu ft airspace 1SV12B)
Quantity: 1

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

  • Single 12" Vented MDF Enclosure
  • Holds one 12" subwoofer
  • 3/4 MDF (Medium Density Fiberboard) Construction

good

The following review is for 1SV12B, which is a part of the bundle you are viewing.

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 very nice, exact specs below.

The following review is for 1SV12B, which is a part of the bundle you are viewing.

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.

well built box

The following review is for 1SV12B, which is a part of the bundle you are viewing.

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.

Not bad

The following review is for 1SV12B, which is a part of the bundle you are viewing.

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.

Great Prefab box

The following review is for 1SV12B, which is a part of the bundle you are viewing.

I would highly recommend this box it sounds like it is tuned between 34-36hz hits lows really good unlike i was expecting since it is vented. I had a rockford fosgate p3 and it sounded amazing in the box and now I have an Alpine type S in there until my new p3 comes back in and the type s even sounds great i didnt think a type s would pound like it did. Good box would def recommend and buy again if need be.

Awesome box

The following review is for 1SV12B, which is a part of the bundle you are viewing.

This box sounds great coupled with a Pioneer Champion Series Pro and 1500 watt amp. Very deep bass tones and very loud. Definitely would recommend.

Worth the space

The following review is for 1SV12B, which is a part of the bundle you are viewing.

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.

This cost more then the gray one but they both perform the same just that the black exterior looks way better then the gray
