Ground Zero Iridium GZIW 250 10インチ 4Ω サブウーファー 250W RMS

Klippel optimization shows—even at high volume, the cone stays tight and controlled, no muddiness. The long stroke rubber surround gives it a surprising amount of punch for a 10-inch. Handled my rock playlist without breaking a sweat.

The aluminum cast basket feels rock solid, and the rubber surround has plenty of flex for that long stroke. I’ve only got about ten hours on it, but it’s already blending tight and punchy in my trunk.

The aluminum cast basket makes it feel way more solid than subs twice the price, and the long stroke rubber surround gives it that deep, controlled punch I was after. Hooked it up to a modest amp and it handles the 250w RMS without breaking a sweat.
