Worked for me

Perfect box for JL10W0

The following review is for 10SAL, which is a part of the bundle you are viewing.

It.s about .05 bigger than recommended but I'm willing to bet you can't tell the difference. Built extremely well for the price. I would recommend it and would buy it again.

10sal box review 2016 .75cf

The following review is for 10SAL, which is a part of the bundle you are viewing.

Purchased 10sal 10" subwoofer box .75cf from Sonicelectronix because of good price and shipping, and this box seemed to meet my needs as the diminsions were close. The height of the box is actually a fraction smaller than the 14" listed, but bigger than 13.5 that the manufacture lists. It is maybe 1/8" or 1/4" shy of 14", and it fit perfect. Upside is build quality for price, and spring clip wire connector. Down Side is that build quality is not top notch (expected), there is no pollyfill, you must solder (or connect) your own speaker wire (expected, as I would have replaced it anyway), and the biggest gripe is the bix isnt sealed in the seams. They tried but missed the actual gaps. Lots of silicone fixed this easy from the inside. Note: That with any box larger than speaker specs can be downsized by adding spacer blocks inside using simple math or online calculator ... Anyway, you must drill your own screw holes but that is good because not all speakers are the same. Overall this is a great box. Well worth the price if you dont want to build your own. It is medium quality built. For a prefab box it is strong. 4 stars.

Good budget box

The following review is for 10SAL, which is a part of the bundle you are viewing.

Well built and nothings wrong with it. I seen in some reviews that the terminal pieces were janky. But mine came perfect. Looks nice. It’s small and compact perfect for what I’m trying to do. See specs for the size.

GREAT LINE of ENCLOSURES

The following review is for 10SAL, which is a part of the bundle you are viewing.

The Atrend boxes are great. They are well constructed, and look great on the outside. I needed a small enclosure for a 10" and this box was perfect. Sounds amazing.
