good box

I got this box originally for two soundqubed subs but the airspace was too small but still sounded good SQ n bass was fine just wasnt how i wanted. so i bought two of skar audios new IX series 8 subs and the max ported valume is .75 soundqubed was 1.25. anyway these subs sound badass in this box i believe the box is tuned around 40hz n has good bass n SQ. if you buy this box get subs that need around .75 cu MAX not minimum. and they will sound good. look and design got 4 stars kuz i dont like the stupid atrend emblem.

great spl box but was damaged on arrival

This dual 8" ported box sounds amaxing. I have 2 dc audio m3. Running a kicker 1200 watt amp. Wow great sound. Only downside is port was broken. If sonicelectronix could package the box better would have prevented damage. Didn't want to deal with returning it so I just glued it.

Excellent Product

I bought this speaker box hoping to get a better sounding box than the last one I had. This box arrived well packaged and the quality craftsmanship shows. The carpet is nicely put together so that you cannot see where the pieces come together. The inside was caulked very well. Overall excellent product and quick delivery.

Good Box

This box was almost perfect for my Massive Audio Summo 84 subs. I say almost simply because I did have to sand out the holes. Otherwise the build seems good. Once my subs were installed they came alive. I do want to point out that the pics suggest a single common chamber because you can see both terminal cups through one hole but there is 2 separate chambers (I prefer that anyway). Overall very satisfied with this box.

Good box, bad specs

Thus is a very well built box. Everything is accurate, but the hole cut out diameter it is not 7-1/4, slightly smaller maybe 7-1/8 to 7

Great Box

I had 2 NVX VS subs in this badboy and they sounded awesome for a couple little guys. I would definitely recommend this box

Perfect!

I put 2 NVX VSW82's in this enclosure. Wow! Powered by an NVX VAD11005. This amp and enclosure make these lil babies BOOM BIG TIME! The enclosure is a perfect fit for my CTS. Doesn't take up too much space, but does the job wonderfully! I also have the single version of this enclosure. Playing with subwoofers to see which my wife prefers for her vehicle. The box is sturdy, well put together, and pretty. It looks good and sounds better! Thanks again to the wonderful team at Sonic!
