Smart looks and smarter sound ~ that's the story of the MTX Thunder6000 series T6104A 10-inch subwoofer. A 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 an 2-inch four-layer voice coil will electrify your ears with outstanding output.
