Ground Zero GZUB 8BR vented enclosure subwoofer - 8", 300 W RMS, 2x2 Ω, 40 Hz

Ground Zero GZUB 8BR is a compact, pre-loaded bass reflex subwoofer from the Ground Zero Uranium series. The robust and resonance-free MDF enclosure provides low-frequency reproduction without the need for high amplifier power.

The enclosure features a Ground Zero GZUW 8SQ-D2 subwoofer, a cast aluminum basket, and an airflow-optimized bass reflex port. This solution is perfect when you want a high-quality, space-saving bass package without the need for a separate enclosure project.

Enclosure recommendation

The driver comes pre-installed in a 20.5-liter bass reflex enclosure. The tuning frequency of the box is 40 Hz and the port size is 1 x 7 cm, so no separate enclosure design is required.
