Sonic Sub Box: 1BV12 (Black)

Best bandpass enclosure

Ive had this exact style of bandpass enclosure years and years ago and its amazing what it can do. I bought this one and have had it for about 2 years now. Solid box, performance is insane. I had a single ppi pcx 124 loaded and on an alpine mrp m500 and this thing just crushes. Turned a small chip in my windshield into a 1ft crack, rattles everything. The bad thing about it is you cant fit a very large sub with a big magnet. I tried to fit a RE audio in it and it will not fit. Buyer beware, make sure to do your homework and find the right sub.

Works great

First impressions... the terminal cup is crap, the plexiglass is a bit too thin, and there is some exposed MDF(without paint) in the port. Oh and the carpet on the inside is only partially glued in. So after some gluing and a bit of black paint this box looks awesome.

Performance wise, this thing is a beast! I've got 1200rms pushing my SPL and just switched from a sealed box to this one. It is so clear, and so intense, I really can't believe it.

GET MORE THAN YOU PAID FOR

Was looking for a bandpass box I saw this one and @ the price & free shipping from Sonic the box was sent to my house. I had to get it...to my suprise the box was pretty solid im running a thunder 7500 @ 470 watts RMS & the box hits hard the mtx loves it,, I only replaced the plexi to a thicker piece,, it does everything i would want it to do & more,,,,,

Great quality built box but not so great sound

I purchased this box as a present to my girlfriend for her new 12" alpine R. Me knowing that she probably wouldn't tell a difference in sound quality from a bypass box to a ported box, I purchased this box. It looks great and had the nice plexi glass front I assumed she'd be very happy but when we received the package it was humongous! I know they give the dimensions but never thought itd be that big. Again it looked great and the speaker fit fine. I got everything wired up and started to tune the amp with her car speakers, trying to get that well-rounded sound but never could with this box. It would hit so hard with a specific sound frequency but when it got to high or low bass there was no bass. I would talk to people that knew about systems and me knowing a good bit about them would ask questions and let them hear. Sometimes they said it was the amp not having enough power but that was just ludicrous. The amp we used was an alpine m500 and if you owned that amp you'd know it had major power. A week later I purchased another box, a Polk audio ported box. After installed the speaker and bass came alive. It almost has heart stopping bass! Now I don't like bashing products unless they deserve it but this product wasn't bad for the price. Just didn't work with my girlfriends system. It was my fault for thinking that if it looked nice maybe it'd sound nice but that wasn't the case.
