What reviewers say

Owners generally appreciate the solid build quality and the ability to run a three-sub setup without the complexity of a custom build. Some users noted that the internal volume is better suited for specific entry-level to mid-range drivers rather than high-excursion competition subs.

What people mention

Build QualityPraisedThe MDF panels are thick and the joints are well-sealed to prevent air leaks.
Size and FitMixedWhile it fits three subs, the overall width may be too large for compact car trunks.
TerminalsCriticisedSome users found the plastic spring clips on the terminal cups to be fragile.
