10 inch Sub woofer THUNDER 6104 Thunder6000 series T6104A 10" subwoofer. An mica-filled poly cone is butressed with eight stiffening ribs, so it keeps its shape even when you pour on the power! The cones are coated with spun aluminum for a "bulletproof" appearance.
The NBR (Nitrile Butadiene Rubber) surround and gasket are fabricated as a single piece to prevent air leaks around the woofer. Spider Plateau Venting draws cool air into the speaker for better performance. An oversized magnet structure and 2" four-layer voice coil will electrify your ears with outstanding output. Asymmetrical linear drive system (ALDS) — spreads stress evenly across the suspension for high output with low distortion
