Compact Bass Performance

Designed for a perfect subwoofer fit, this enclosure features a precise 7 1/8" cutout diameter and a 0.88 ft³ air volume for clean, punchy bass. Its 6" mounting depth (with a 5 1/2" magnet diameter) allows compatibility with a wide range of subwoofers while keeping installation simple. Weighing just 24 lbs, it offers a strong yet lightweight build ideal for powerful sound without added bulk.

Perfect Fit, Powerful Build

Designed with a balanced shape for a clean and secure installation, this enclosure measures 10 1/4" in height and 28 1/4" in length, giving your setup a solid, professional look. The smart depth design—11" at the top and 16 1/2" at the bottom—maximizes internal space for better performance and deeper bass response. Built to fit smoothly while enhancing sound output, it’s a reliable upgrade for anyone serious about their audio system.
