Ground Zero Iridium GZIW 300 12インチ 4オーム サブウーファー 350W RMS

This subwoofer’s long stroke rubber surround gives it some serious excursion without bottoming out. Hooked it up in a sealed box and the low end is tight and punchy.

The 3D cone really holds up even when I push the volume hard—no distortion, just clean, deep bass that shakes the seats. The long stroke surround moves like it’s got endless travel, and the steel basket feels rock solid in my enclosure. Best upgrade I’ve made to my system so far.

Installed this in my trunk last weekend and the long stroke rubber surround handles low bass without any distortion. The steel basket feels solid and the whole thing stays perfectly in place even at higher volumes.
