Revision:1.0 | Date: 2015-4-27
SDS-P830657
Woofer
The SDS compact subwoofer family offers low resonant frequency performance, ideally suited for compact sealed
enclosures. This 6.5 inch 8 ohm member of the SDS family offer a coated paper cone with rubber surround, a high
power voice coil suspended in a ferrite magnet motor, and a narrow-profile steel basket, shaped to fit into narrow
cabinets.
