Perfect box!

Shipped on time, fit my 12" bass line so well I used it without screwing the sub in and didn't even budge. Very well built just wish it hard push terminals on the back instead of screw ons

Nice box

This is a nice 12" box. Sounds great with Kicker Comp sub and matching amp in my VW Passat. Looks great too.

Great box for any 12" sub

Would recommend to anyone that likes SPL in their bass I currently have my 12" alpine bass line subwoofer in it on a 1000.2 autotek amp and it hits perfectly with my two 9" in a 4th order landmass box on my dual 580.2 amp

The price for such a quality box is amazing! Put a super inexpensive sub in it and it sounds surprisingly good. And the blue looks great! The free shipping is great and was only held up thru UPS cuz of the blizzard we had here. Definitely would recommend sonicelectronix and this product to everyone!

Great Enclosure

I'm new to stereo system setups but a friend recommended this kind of enclosure and this box has exceeded my expectations. The color choice is a cool feature and the box is very solidly built.

Amazing Box For $50

For $50, you will not find a better value. Everything with this box has been a plus with only one flaw.

-Durable, heavy, and made of quality materials
-Stuffed with bass friendly material
-Ported to pound
-Looks amazing

-The hookup port in the back is actually pretty bad, its actually not a very conductive port for your sub, and I instead wired directly to the sub with the wire running in through the ported hole. It sounds great and is an easy fix for this issue.

Belva BBX112BL ported box

No complaints here . Great deep thunderous bass . This puppy really moves the air and hits accurate bass low low frequencies !! The box volume is about 90 thousands cubed bigger then the recommended enclosure butt the difference is so minute , it makes little difference in the sound quality . Highly recommend this box . well made great out put , Along with the supurb sonic service and quality products . I highly recommend Sonic and products !! TWO THUMBS UP !!!!

OK box for the $$

I bought this box with the JBL MS-A5001 amp. I hooked everything up and put my 12" Kicker compVr dual 4ohm subwoofer in it. At first I was disappointed in what I thought was the amp. It just didin't seem to hit as hard as you would expect a true 500watt (750watt @2ohm) amp should. Then I changed back to one of my old sealed sub woofer boxes and realized that it wasn't the amp. Although the box is designed beautifully and very sturdy, it wasn't a good match for my Kicker sub woofer. I won't give the box a bad rating for this, it just may be tuned to a different speaker is all. Overall, this box is a good value for the price.

Excellent Quality and Performane

Buying this enclosure was a good decision and allowed me to spend more time building an excellent crossover to match a Seismic Coax-12 speaker. The end result was an outdoor PA speaker with HiFi sound quality. You honestly cannot beat the price and the free shipping is uncommon on something this heavy.

The only product suggestion I would make to Belva would be to change the port design to lower the resonant frequency.

Strong and Sexy

Bought this for a sub that needed more air space.. Ended up putting in a type R instead.. which this box is too big for.. but it actually sounds better than the sealed box I had (don't know why). Great punch on all bass freq. and basses out hard on the low stuff. Very sturdy built and looks great. For a prefab, you can't beat it.

-1 on Features because it's got those screw type terminals.
