Broken.Update seller sent me a new replacement undamaged even after Amazon refunded my money good reliable seller.Box is good quality.

the quality has been very good so far and the sound is good

I personally give the box 5 stars. They did a really good job on this box. You can se a little of the seaming but it’s nowhere near annoying. The box did arrive with a hole in the packaging but no damage to the sub box, luckily. Very solid, heavy, unflawed and performs with the presence of an earthquake! When pushed, runs clean with no rumble. Ran a sound generator thru it and felt it at 32Hz as specified, tuned nicely. Loaded it with a Skar Audio SDR-D4 15” 1200 watt sub which has a really thick and wide suspension surrounding so I paired it with the PowerBass SWB 15G - 15” Subwoofer Grill. It fit perfectly tight inside the Skar mounting gasket with a little work. Like prying a tire on a bicycle rim, but not that bad. It worked great because of its extra height. Loved the look and the performance. I use this as a home theater sub because (1) Most subs I’ve gotten in the past clipped out early, probably cheap; (2) this combo is priced well for me since I already have a Crown 1502 amp in bridge mode pushing 1050 watts. Woofer wired for 8 ohms. Hope this review helps you decide what you want to do.

This build quality is horrendous. No idea how this made it through the simplest of quality control. Bought it as new but it looks like it’s been in someone’s basement for 10 years. I could make something better from scraps laying around in my workshop. Oh, not to mention that my speaker wouldn’t even fit in it.

Fits oversized competition woofers skar vxf 15. Tuned correctly! I just wished they had a 3.0 cubic feet box. My speaker calls for 3.2 , but speaker terminal post too small.. Good build nothing for me to cut or screw down front baffle is 1" thick..perfect.. Good price!

For me this works perfect for what I need in a 15" enclosure and I have 2. That said the carpet covering does seem to be optimized for less waste so looking very closely the cuts might be noticed. That does not matter in my application though and the solid construction and tuning frequency do matter. The only real issue I have is that the push terminal block is glued instead of screwed (one of them was press-fit) so might not be easily replaced with something better but does accept at least 14 ga. speaker wire which also works for me.

Good box for the price. Tho it states 2.7 cf tuned to 32. I put the measurements in to my box builder software and it was 1.77 tuned to 38hz.

Very good
