Solid Enclosure
This is a solid box. It really is 0.75” throughout. Very well constructed. Very rare find to get just over a net cubic foot for a prefab box in this price range. I’m giving it a 4/5 because it was tuned way too high for my taste. It’s tuned to around 44/45 hz. Luckily the Port width is 1.5 “ so I was able to tune it with a 2x4. See pic. It sounds fantastic.

Guinea pig review
It seems I'm the only one that bought these from here lol, but you get what you pay for. Yes they are pricey but they are equivalent to infinity Kappa 93ix 6x9 in terms of crisp and clean. These subs are great so far, I bought them about 9 months ago and just put them in. So I can't speak on durability but great wire connectors that's included and the overall sound is great. If you have the extra money, I suggest getting it. I have 2 10's with the nvx 2000 watt amp running in my 71 Superbeetle. I was running a single 400 watt 10 inch Memphis sub with a 400 watt kicker amp, he did his thing and will again in the future. I just wanted to go back to duals in the bug. It's been since my college days. Buy it, only if you have the funds.

Great sounding subwoofer
I wanted some better low end in my 24 VW GTI. I also wanted to keep some room in my hatch. This Alpine sub worked out very well. I have it in a .65 cubic foot enclosure that still leaves me plenty of space. It sounds great too. It’s punchy and goes deep. Provides more than enough bass for my needs.

Excellent Choice!
this was an excellent choice for my nvx sub. it matched the specifications to it and this box makes a huge difference in the sound quality of it too. I highly recommend this box and overall am satisfied with my purchase.

Great Sub
Very happy with this sub. Durable and able to deliver, sound quality is really good and decent low end for a 10” sub. Would purchase again
