Tymphany's SDS Series 830855 woofer is intended for use in small surround sound speakers, compact monitors, as the dedicated midrange component in 3-way or 4-way systems, or even as a small PC subwoofer.
The 830855 features a truncated cosmetic stamped steel frame, which allows it to fit in small cabinets. Venting below the spider and at the cone apex reduces trapped air, resulting in quieter operation and a cooler voice coil. Treated paper cone with rubber surround and inverted dust cap.
