    • Excellent quality
Color: Black Style: Angled Pair Sealed
This company seems to build quality enclosures. These are no exception. Well built and exactly what I was looking for. I did have to purchase some poly for these. The other selections appear to include the poly but not these. Shipping package was secure as well.

Awesome build quality. Just as described in the video. I used these to expand my home stereo system. The Kenwood speakers 6 x 9 Are phenomenal. Together they fill the room with high fidelity sound. These speaker boxes are complete. Nothing else to buy. Speakers fit perfectly. Comes with wiring. Full sound insulation inside. And very nice connecting terminals on the back. No disappointment here…. Well, worth the money..! ... show more

Color: Charcoal Style: Angled Pair Sealed
I ordered these for my husband who was adamant about putting speakers in his single cab truck. Obviously putting in subwoofers was not an option so he chose to put in 4 6x9's to give him better sound than simple factory speakers. I ordered him 2 pairs, he screwed 2 of the boxes together and placed each pair behind each seat. These are constructed out of 3/4" MDF boards so tehy are very sturdy. They are properly glued and sealed so the bas response is superb. The dimensions of these are smaller than some I've seen and work well in the small space my husband has placed them. My husband is 6'4 and needs all the leg room his truck will allow so losing space for a speaker box was not an option and these fit perfect in the small space without cutting into his leg room. They are small enough to fit under the seat but he prefers the sound when placed behind the seat. ... show more

I bought Bbox based on the quality of the representation in the pictures and video, and the listed measurements. After receiving them I realized the measurements are a little smaller than stated and the seam glue has cracked and shrunk exposing gaps in the seams. These are still great high quality speaker boxes that are well made with 5/8” thick MDF but I need something larger so I ordered the Stinger brand which is true to stated measurements and is of 5/8” thick MDF. I took some pictures of the Bbox and the Stinger box for comparison in case someone is looking for more air space. Again, the Bbox is of great quality but so is the Stinger brand, both brands are made in China. The Stinger brand sprayed glue on every inch of the internal wood so the Polyfill sticks to it, the Bbox only put some glue lines on the internal wood causing the Polyfill to separate from the wood. The seams are tighter on the Stinger box. I realize these are just speaker boxes but in having a quality high power stereo system, every little detail counts to have quality sound and mid bass. Wish I got paid for this. I hope the helps someone. ... show more

I needed to put some decent speakers into my restored 92 Geo Metro convertible without cutting everything up. The theme of my car is the 90s and what is more 90s then speaker boxes? I started browsing on Amazon and honestly it was a lot. I would find a box and someone would complain the carpet is cheap or the cuts were crooked. I spent way too long reading trying to figure out what one to get. I just happened to grab these and hoped for the best. They arrived and honestly the quality is way better than I could imagine. I threw my Pioneer 6x9s in these bad boys and hooked them up to the Metro. They fit like they should, and the boxes are heavy in a good way. Very impressed with the quality. We were cruising to Atlantis Morissette no time at all. If you happen to be looking for some speaker boxes (of course you are if you've read to this point) don't worry about sound blah blah blah, you can order these and be happy. ... show more
