Nice for a prefab and sounds great.
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. ... show more

Awesome Enclosure! Makes my Rockford P3D4 12in sound two!
OK. So I already own the dual 12in enclosure so I knew the build quality would be great. My concern was the port. Now I already said the build quality is great, as in its solid, sturdy, with that coating acting as a shield from the weather as well (humidity and wet weather I mean) it's a great build. But it isn't exactly ported like a high end enclosure is. It's close, as you see in my photos, they have the port at the end of a long box. And that acts as an enhancer for the bass. Well it's supposed to. Its supposed to be more obstructed along that long box hole before the port. Kinda like a tight maze of wood all down that hole. That makes it almost like the box is sealed because the air has so much to get thru before the opening, and this enhances the bass even more. Don't get me wrong. This box makes my Rockford P3D4 12 SLAMM. But with that port, it doesn't produce the deeper lines of bass. Those low rumbles So as you can see in my photos, I sealed my dual 12 enclosure and it made it sound extremely better and made it be able to produce those really low bass lines. So I am probably going to seal up the port on this box as well. I've always liked sealed enclosures better man. They just sound much better to me. But to each his own man. Regardless, this box is awesome! And I highly recommend it! If you only want one subwoofer in your vehicle, this is the box you want for it. It seriously sounds like I have two subwoofers in my car ... show more

Came damaged but still functional
Two of the boards are separated a little bit and showing bare wood, right on the long edge of the box. Structurally it hasn’t affected anything, it’s just a noticeable “crack” that would bother anybody who is getting it for the looks. As far as doing it’s job, the box performs. Fits my type r 12 and almost doubled the sound compared to my old sealed box. People can’t believe it’s only one sub! If you want low lows this may not be for you, but I enjoy my bass in the high 30-low 40 hz range and this enclosure is spot on. Price is about average, not too bad but not the cheapest either. Minus one star because of the crack, otherwise 5 star product for sure. ... show more

A must buy.
Great company. Love the dyna mat. Perfect for any sub. Highly recommend.

The loudest box I have ever heard, bar none.
Like a few of the other reviewers on here, I have a single 12” Rockford Fosgate Punch P3D4 (dual 4ohm voice coils) wired to 2ohms. I have a Kenwood KAC-9106D bridged to 2 ohms for 1,000 watts RMS, 2,000 watts MAX that pushes it well. I’ve been into car audio for the better part of 25 years and have had about every configuration you can think of, from stock equipment to thousands of watts being fed to 15” and 18” subs which break windshields. I wasn’t expecting the world out of my current little system but want it to be the best it can be. I had my 12” Fosgate in a generic pre-fab ported box that sounded okay, but I figured it wouldn’t hurt to pick up a box that had the precise air volume that my sub called for, (1.79 cf) so I grabbed the Q-Bomb single 12” version 1.8 cf. If you are even thinking about picking up this box and are reading this review looking for advice, BUY THE BOX. This thing is bananas. My bass is twice as loud as my old box and I haven’t touched my amp settings. All I did was change the box. These things are ridiculously sturdy, clean looking and sounding and unequivocally SLAM. Hard. This is easily the best box I’ve ever had. I’d pay twice the price for these results all day long. I’m extremely happy and completely astonished with it. It’s freaking loud, I’m telling you. Especially if you have a Fosgate P3 or anything with the same airspace requirements. Get it. Do it. You’ll LOVE it. ... show more

LEGIT!
Legitimately made my system sound like it was something new and Even better!! Seal the inside W/ silicone were all your joints meet ,even inside the port. Helps keep everything nice and tight from flexing You won't be disappointed.

Air leak coming from terminal cup. Easy fix.
The construction of this enclosure seems pretty solid compared to other similarly priced products. Perfect ported airspace for my JL Audio 12Wv3-4. Only issue I had was that there was a major air leak coming from the wiring terminal. Even at low volumes, I was getting a loud vibration/distortion sound coming from the terminal cup. Fortunately, I was able to easily fix this by adding some foam speaker sealing tape onto the enclosure around where the terminal cup is secured. After doing this my sub hit hard with no undesirable noise. ... show more
