    • Fantastic box
Size: 1 Pack
Very good quality box very well built and I couldn't stress bad enough that it is very well built I've built many many boxes and I bought mini boxes and a lot of the boxes I bought have been cheaply built and very quickly put together this one doesn't look like that it's solid and it's got a great sound and it will hold together for a big speaker I'm playing a DD audio 1200 watt RMS 12-in speaker through it and it's handling it just fine ... show more

Great quality box. It was over a week late on delivery. Don’t know if it was the company or the carrier but the product is as described and sturdy built.

    • Couple issues
Size: 1 Pack
At first glance it seems to be a nicely finished and well put together enclosure, and it's not far from that. But there are a couple of issues to note. 1) the face panel is much thicker than other sides so the pictures give a skewed perceived thickness. 2) the thin other panels are dense and a little tricky to get a wood screw through, many simply stripped and free spun. 3) included wire cup, it's a problem many prefabs have, it's just cheap. Leaving the hole out entirely would be an improvement. ... show more

    • Worth every penny
Size: 1 Pack
Using this enclosure with an American Bass Elite 1244, being pushed by an Audiopipe APCLE-18001D @ 2 ohms. Installed in a small 4 door sedan first and did not quite get the sound I was looking for. Then installed in a extended cab pickup truck and oh man the sound was awesome. You can hear the notes clearly and the SPL is so satisfying. If you have a sub that requires more than 2.5 cubic feet I would recommend this enclosure all day long. Update: Had the box for almost 1 year now and its still holding up well. Just upgraded my subwoofer from the AB Elite 1244 to an American Bass HD 12 D2. Was pushing 1100rms now will be pushing 1800rms and see how well it holds up. Update: I have been running the American Bass HD 12 D2 in this box for over a year now. I have not had a single issue from this box yet. I did like most of the other reviewers here and added in a piece of wood to lengthen the port for a bit lower tuning. ... show more

    • You get what you pay for-Bottom line-
Size: 1 Pack
Is listed as 3/4” mdf. It is actually 1/2”! Box def hits hard but like others, need to length the port or you’ll hear zero lows period. That’s how I discovered the box being 1/2” when I went to lengthen the port. Guess you get what you pay for🤷♂️

Size: 1 Pack
The Subwoofer box is very good,but the tuning was off a little but I fixed is with an extra peace of MDF wood and now it is tuned to the correct tune that I was aiming for and that was all,but over all it is an amazing subwoofer box and came in amazing shape and nothing was broken or messed up on the box at all and was over all very very happy with the product and wish that anyone that buys this product has a good time and has an amazing audio/jam time. ... show more
