QPower Heavy Duty Single Vented Subwoofer Enclosure, Charcoal Gray, 15 Inch

So far I’ve had 3 months and box quality is well made, especially for price. The sound is amazing, box is tuned to about 35hz and hits low and loud for my 1000w rms(I do run my sub inverted so that lowers tuning output). You will have to add screws to keep from tearing itself apart but that’s common with the “cheaper” boxes. It did come caulked correctly. Box works as it should and looks amazing. Size is to spec mentioned. Remember to pre drill holes for screws and #6 sheetrock screw work just fine. In short, buy one.

I've read a lot of the AI generated reviews in my opinion there was somebody who said that they measured out the box and that it was smaller in this or that or whatever this is what I know I've been messing around with subwoofers well we used to call them woofers I've been messing around with this stuff since I was probably 15 years old and I'm a lot older now I will say this the boxes on the heavy side it's big And I recently purchased this item and I put a subwoofer in it and I'm not running a lot of power under a 1000 W and this box definitely does the job I would highly recommend it it's a great buy for anybody that wants to put a decent subwoofer in it just make sure that the manufacturer's suggestions call for this size of box I would think it would match up well with a kicker subwoofer anyways I just wanted to talk about it because I did purchase it and I've been happy with the item so far I don't know how long it will last or it's durability but I'm optimistic but I will say that I would say if you put a quality subwoofer in this box and put maybe 1200 W RMS to it you would be fantastically surprised don't forget play around with EQ settings row windows up and down see what works best and wait for the subwoofer to break in I highly recommend this item update it's been 6 months later the slot Port has come a loose on a small corner on one side so when the base hits It's getting some kind of a diving board type sound going on I can't really complain too much because for roughly over 5 months it was okay maybe because I put a bigger amp in a thousand Watts RMS but anyhow try to use a little bit more glue but other than that I really can't complain too much I've never had a box come apart at the seam where the Loctite is put that's supposed to actually be stronger than the wood

Honestly I’m impressed. I’ve built every single sub box I’ve ever wanted for the past 20 years. And to be real, I just didn’t feel like building one for this 15. So I ordered this qbomb box. I was worried about it being tuned to 37hz since I like the lows. (28hz-32HZ) but this box actually performs well. I’m happy with my purchase. On the manufacturing side of things I don’t like that the terminal cup is only press fitted in the box with no screws. And they should use corner protectors for shipping.

this box is perfect for my audiozee 15d2 havoc subwoofer with a vevor bp3000.1 amp powering it. it was shipped in just a cardboard box so expect some damage to the corners no matter what BUT for $85 shipped its a no brainer if this box will fit in your space. i plan on taking all the carpet off and glueing a layer of 13 ply birch over the box and that will be the fix. if you have less xmax sub you should not need to do much modification except for corner/side bracing and some pl max glue . THIS setup shakes my 2012 dodge caravan so much the rearview mirror fell off the windshield!

Hoping to hear back an get warranty but as it stands right now wouldn't buy again hopefully it's just a defect box wasn't even 2 months old Before it started rattling an coming apart haven't had issues with this brand in the past so we shall see but as of right now not a good recommendation

Not a very great box for a big subwoofer but it will take a mid size subwoofer no problem. The tuning is kinda high but is pretty loud for a 80$ box. Only thing I recommend is don’t take the subwoofer in and out of the box a lot of times. After taking my subwoofer out a lot of times the wood begins to break and it becomes very difficult to screw you subwoofer back in the box and get it to seal correctly.

Works good but I had to add external screws to baffle as sub was making box separate. Other than that it's good.

Long story short, I traded my ported 12s for a 15 in a sealed box. I regretted the decision at first, but then I bought this and now the single 15” hits just as hard if not harder than my 12s did, on less power. I’ve seen mixed reviews about build quality, but mine came in with no issues or loose areas. Sounds great in my little beater wagon.
