### ⭐⭐⭐⭐⭐ Nice enclosure
*by A***S on December 6, 2025*

So far so good. It seems well made. No strange rattles or anything. Speakers binding connectors seem good. Good enclosure for the money.

### ⭐⭐⭐⭐⭐ Bass on a Budget
*by A***R on October 15, 2025*

### ⭐⭐⭐⭐⭐ Good Speaker Box
*by E***C on September 14, 2024*

This is a pretty good box. I've never seen a box this small made with 3/4 inch high grade ply wood and 1.0 inch front, usually boxes this size are made from 5/8 ply wood. The specs say it's port is tuned to 38 hertz, the center of the tune is about 40, but it does do a pretty good job of loading the cone down to 38. It does decent down to 35 but below that the cone really moves. This is good enough though, the previous box I used looked the same but was tuned to 45, at 600 watts rms it definitely was to much at 32.7 hertz. The new box actually loads the cone enough to keep it from moving to much at 32.7, it makes a lot of wind noise but I can only hear it when I turn off the rest of the music. This box isn't as good as my big 2 cubic foot box which is tuned to 29 and really loads the cone at 32.7 so it's fairly quiet, but the big box also weighs 57 pounds where this box weighs 33 pounds, much better! :) The weight really does make a difference, both the small and big subs are used in a portable karaoke system. The weights above are with a Planet Audio AC12D installed.
