Atrend Bbox 8" Dual Vented

Decent quality no complaints got looks good for the money

The media could not be loaded.  Good box. Well made but wholes for subs were small. Had to open them up for two 8 inch Skar audio subs.

Product arrived in perfect condition (fall '23). I added a bit of sound dampening material along the side and across bottom that vent starts on. Ct Sounds Tropo 8 and Skar SDR8 both fit perfectly (7.2in cutout). Sound quality is very good, and it extended the usable low end of the subs. They were in a sealed enclosure prior to this. I tested the sound with different Hz tones. 38 was very strong, 35 was still strong, and 32 was where roll off started but much improved over the sealed boxes. 28hz was much softer, but the note was still plainly heard. Hope this helps. Currently running 2 Ct Sounds Tropo 8 in it with 500w amp (250w RMS) @ 2ohm. This review is for the 8in dual sub box tuned to 32hz.

The box is built good. but the glue for the carpet. Is really poor. Had to glue a few different spots on the box. They were over an inch. But other then that the box sounds good for the price

$92 descent, unless it’s a custom box, I’m not building another one the price of materials and labor equals out to a lot more than $92 and it does just so happen to be real 3/4” MDF, which ain’t cheap, and the carpet has a really nice color it is .7 ft.³. not including the port, .85 ft.³ including the port per/sub, These kappa’s call for 1 ft.³ each ideally, apparently they’re not too fussy because they sound BA in this box
