Great box with great build quality and value. I have a Destroyer15D2 wired to 2ohms on 4k watts in this enclosure and so far everything is working as intended. It handles the upper 20 hz range like a champ. It also really does have a 1 inch baffle. Also, the sub dropped right in with a perfect fit. 10/10 for build quality for sure. I have this in a 014 BMW 535i - still have a lil bit of trunk space. Lol.

I dropped a Diamond Audio 15" D9 sub into this enclosure, and let me tell you—it HITS. The bass is deep, clean, and powerful. You can feel it in your chest, and it rattles everything in the best way possible. The vented design really lets the sub breathe and push serious air. Build quality is top-notch. The box feels super solid and well-constructed—no rattles, no flexing, just pure performance. It fits perfectly in my trunk and looks clean too. Honestly, I couldn’t be happier with this setup. If you’ve got a beast of a sub like the D9, this box will let it shine. Highly recommend for anyone who wants to get the most out of their 15" sub!

Great sound and solid box

I have a Skar Audio VXF 15 D2 installed in this box powered by deaf bounce 4900.1. Definitely the bass is hitting much harder!! Excellent DB increase! I did not measure it, so do not ask. The previous box was 2.7 cub/feet tuned 32 hz weak build. The box flexed plus there was no sound dampening. I know I lost db when the volume increased. The reason why I bought this vs the skar audio box, the skar audio box was too tall to fit into my trunk 2013 GS350. This box did the trick low profile. This box is 3 cubic/feet , tuned to 32 hz I love it I love it!❤️❤️ hits harder now I have to turn volume down on amp..lmao.

This box is extremely well built put some sound deadening pads in there and you have a custom quality prefab box

I ordered this enclosure because the first one (from a different company) was cheaply built and came loose at the port. I bought this Harmony box and right off the bad the difference in quality was amazing. The sub I installed sounded fantastic inside the enclosure. My only complaint is the tuning of the enclosure. I wish it was tuned at 28Hz instead of 32hz. This is a solid box for the price and if you are in the fence about purchasing it GO FOR IT!!

nice made heavy

This box has a great sound 2 it it gives the speaker such a great, low end sound
