Q Power HD112VL Single 12 Inch SPL XL Heavy Duty Side Ported Subwoofer Box Enclosure with Durable Carpet Covering for Car Audio Systems

So far so good. It seems well made. No strange rattles or anything. Speakers binding connectors seem good. Good enclosure for the money.

Box is very sturdy! I installed a 12" JVC DRVN sub in it and the sound is great. Woofer fit just as it should and functions perfect. I did replace the terminal with a screw down style. It is a great combo now.

This is a pretty good box. I've never seen a box this small made with 3/4 inch high grade ply wood and 1.0 inch front, usually boxes this size are made from 5/8 ply wood. The specs say it's port is tuned to 38 hertz, the center of the tune is about 40, but it does do a pretty good job of loading the cone down to 38. It does decent down to 35 but below that the cone really moves. This is good enough though, the previous box I used looked the same but was tuned to 45, at 600 watts rms it definitely was to much at 32.7 hertz. The new box actually loads the cone enough to keep it from moving to much at 32.7, it makes a lot of wind noise but I can only hear it when I turn off the rest of the music. This box isn't as good as my big 2 cubic foot box which is tuned to 29 and really loads the cone at 32.7 so it's fairly quiet, but the big box also weighs 57 pounds where this box weighs 33 pounds, much better! :) The weight really does make a difference, both the small and big subs are used in a portable karaoke system. The weights above are with a Planet Audio AC12D installed.

Great quality emclosure but cheap terminal that is not screwed down . I would advised replacing it to prevent ang leakage if you're anal about those things . 1" baffle is great ! I would have gave 5 starts but for my application and the "12 sub that I have a Kicker comp VR 8 holes were really close to the edge . I had to put 2 layers of 3M tape for it to not have any type of play. It may not be the same for other type of subs . Other than that , the quality of carpet and wood is perfect for what I paid .

Just as described 1 inch baffle, three-quarter inch walls and port wall very satisfied, solid good build for prefab enclosure. Goodbye again.

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

Box is pretty sturdy, but side connector is trash. Rattle apart right before it blew out.

I have this box coming tomorrow and already have this box from Q-power that hits hard. I have the Hiyanka 12 inch competition sub right now and it hits really hard but im looking for a better quality sound. Gonna drop a 12 in CT SOUNDS Tropo XL or the Meso after Christmas since I had 2 grand daughters a month apart not long ago and already had a grandson that turns 5 in February. Gotta spoil them grands. I have a 2010 camaro so im not going too extreme but it beats hard enough already to cause rattles and hurts your chest if you sit in it for too long with a bass cd. I thought this box was a sealed box because I typed that into search but this will give me a idea of how I might make a custom box with 1 inch thick plywood doubled up. I bet that will sound soo freaking good and be heavy as a small car 🤣🤣🤣
