Scan-Speak 22W/4851T00 8" Woofer, Paper Cone, 4 ohm
The Scan-speak 22W/4851T is a new addition to the Revelator line. This robust 8" woofer was designed to provide deep and accurate bass in a small enclosure. This woofer features a 2" voice coil on a titanium former, a low loss linear suspension and symmetric drive motor. The deep set hard paper cone is attached to the frame with a minimal reflection rubber surround. The 9mm X-max ensures good linear travel.
