QPower Single Triangle Car Audio Ported Subwoofer Box, Fits Most 12-Inch Subwoofers - Deep Bass MDF Enclosure with Bed Liner Finish, Tuned to 54 Hertz, 2.2 Cu Ft Air Space

The QPower 12-Inch Single Sealed Subwoofer Enclosure is an excellent choice for anyone looking to get clean, tight bass from their setup. The box feels solid and well-built, with quality carpeting and a perfect internal seal that really helps the sub perform at its best. It fits most 12” subs snugly, and the sound is deep and punchy without being muddy. Installation was easy, and the compact design makes it great for smaller trunks or under-seat setups. For the price, it’s honestly hard to beat — durable, great sound, and built like a tank. Highly recommend for any car audio upgrade!

Worth the money. Good box

This box is great, but you MUST seal it yourself. I paired it up with a Tarantula T5-122 sub. This sub recommends tuning at 30ish hz but it QUAKES in my single cab Chevy. I’m pushing it with a Taramps HD2000-1ohm amp. I adjusted to amp to respond between the recommended Hz for the sub and the 54Hz that the box is tuned at. I have my gain and boost at 1/3 max and it’s hard to breathe when I hit max volume on my stereo. Perfect setup for less than $500. I haven’t broken in the sub yet so I’ll update this review later. They say 3/4 mdf but it seems more like 5/8ths, if you don’t seal the box it will rattle and crack the Berliner coating. Overall this thing has impressed me. Worth the $$ and with the right sub it POUNDS. Do the research, the T5-122 was the best sub I found in my price range to fit the tune of this box.

Good for the price. As others have mentioned you will need to properly seal it save yourself some time and pickup liquid nails and do it before hand so you don't have to pull your sub out and reinstall like me. Shipping was fast. Couple little scufs here and here but no actual damage to the box or liner coating. All in all it's a good box but you must seal it properly!

I bought one of these boxes a little over a year ago for a 10 inch sub it made a huge difference with that sub one of the better boxes I have ever used so now I bought this one which is pretty much exactly like the one for the 10 except for this one's for a 12 and once again it made me major improvements to the sound quality

This box is pretty good. The 12” hole was a tight fit but it seals once you screw in the sub. Overall it’s pretty good and looks good too.

Great sounding box for 1 12". It has some flex to it but it didn't break. I hit it with liquid nails anyway as a precaution. I have a sub in it that's a clone of a Sundown SA classic ( its an Audio Legion S2512) and it sounds great. Low but still very musical. So much so that I chose to run it in my home theater. ( I have a big home theater, very powerful). it's tuned lower than the specs say, like 34hz if memory serves and not alot of port noise either, that's another reason I used it in my home theater setup. I'd buy it again but I wouldn't put anything too big in it. Sundown sa classic or lower. The Resilient Sounds Onyx 12" in the picture has nothing to do with the review, its just too heavy to move out of the way so deal with it, 😆. I would never use this box for something like that monster. BTW, the liner on this box is TOUGH! It's not junk liner. I was surprised how tough it is.

I bought this to upgrade my home theater subwoofer setup. I have a complete Pioneer Elite system and wanted to use the best Pioneer has to offer in subwoofers. (I threw a Pioneer PRO 12 in this box and powering it with a Crown XLS 2502 amp) This box worked perfectly for that. I didnt have to make any modifications for the speaker to fit, but I did take some prevention steps and used liquid nail on the inside corners and then added a layer of polyfil. Probably didnt need to, but I want the best I can get for my budget. Overall the box seems like its going to sound amazing, I haven't put it to the "test" yet but I have high hopes. Good quality and great price.
