The TS-D12D4 12" subwoofer can handle up to 600 W RMS, while providing impressive low-frequency levels. This subwoofer features an injection-molded polypropylene IMPP™ cone infused with Aramid fibers for exceptional precision and strength. A butyl rubber surround supports the subwoofer during cone excursion, to get accurate, hard-hitting bass notes even when the music is turned up loud. When setting up your system, the dual 4Ω voice coils of this subwoofer will give more wiring options.
