Q Power Dual 12 Inch Subwoofer Box, High-Performance Vented Speaker Enclosure, Black

I have used these boxes for several builds. Great sound and quality at a excellent price! I painted this one with tractor enamel and inlaid the groves with black epoxy, matches my clients Dodge Challenger perfectly!

Great product

I enjoy building boxes and the specifically enjoy the design phase as much as I enjoy the final assembly and wiring. So why buy a prefabricated box? It has great reviews and I thought I would give it a try considering I was working on multiple other projects at the same time. So this box would be almost plug and play.Saving time is always a good thing. I was looking at the larger version of this box, however, I wanted it placed up on a shelf unit I built in my shop and wondered if the larger Q-BOMB would fit. I decided that this one was the way to go. I feed it 300 watts at 4 Ohm load. No cutting or filing required as the 2 subwoofers I have for it just dropped right in.The opening is right at 11.1" and the terminals inside the box are decent. If you run some serious power I would upgrade the terminals. I would also add a brace or two if you are going to be pounding with this box. Those two things are why I knocked down a star in durability and a star in material quality.Sound? It sounds nice. I have about 5 days of 11 hours a day of play time on both subs. It is starting to get lower and louder every day. I was curious about placing it up on the middle shelf in the corner of it would work as well as placement on the floor in the corner. I might gain (pun intended) some deeper notes if I dropped it to the floor, however I would have to move a bunch of stuff. I also like it up high as it is protected from me hitting it with something while working in the shop.If you are considering using this for home or shop subwoofer it does the job nicely. I might upgrade the subs - for now they are doing the job quite nicely. Pair this box with two 12" subs and a 300 watt amp and you have a nice set up for home that beats any 12" single home specific self powered subwoofer.Good luck with your project!GOD BLESSjohn

I would and probably will buy again. I used it on my home stereo and the bass thundered.

Build quality and finish are excellent, cubic volume is a bit small though. Nothing that can't be addressed with appropriate drivers for it. Using 2 as a pair, internally wired in serial with 4 ohm drivers to create 8ohm load. Then boxes wired in parallel to drop them both back down to 4ohms, powered by a 4 ohm plate amplifier. The ports help keep the plate amp cool through forced air from driver excursion. They dont sound as good as the VL boxes but the reduced footprint has its applications. Recommended when space is limited, a great sounding box with the right woofers

A lot of reviews say the subwoofer holes are too small which is kinda true. I used some Skar subs and they were just a little bigger than the hole I used a mallet and gently banged the subs in. The box itself arrived really fast and the bass sounds really good, I definitely recommend

Barely. I had to take the cover off the wheel well. I don't keep a spare in the trunk because I'd need a full size or risk tearing the rear end out. It's a tight fit but if you kinda twist it while inserting it will slowly fall into place. Now I just have to figure out how to get the carpet and well cover back underneath it. It would probably be easier if I had an assist but this is a solo project. If you don't pay attention and try shoving it in, you will tear out your surrounds so either put the speakers in after or go slow and steady.My 12" Black Diamonds did not sit flush. I just used foam rubber gasket material to seal the roughly 1/4" gap rather than grinding the holes out. Does the trick. I'm pushing 1500 watts RMS into these speakers and haven't had a crack appear so far. I did reinforce the corners in the back with some square dowel rods before I installed the speakers, just in case, since others said they had managed to break these boxes.
