Pioneer's innovative TS-SW841D 8" subwoofer packs a punch that belies its slender cross-section. Its Air Suspension Control System eliminates the need for a conventional spider structure. Instead, a cushion of locked-in air acts like a spring, providing smooth, precise movement of the woofer. This special design keeps the total depth of the sub comfortably under 3", for bold bass in places regular subwoofers can't fit.

The one-piece die-cast aluminum basket sports a radical fin design that provides extra cooling and rock-solid resonance control. Rugged internal parts, a powerful strontium magnet, and a cone-reinforcing aluminum dust cap round out the package.
