The 26W/4867T a new black Aluminum cone woofer. Aluminum is a good material for subwoofer cones, very stiff and light. These cones reduce distortion and also help cool the voice coil, by conducting heat away from the coil. This woofer has a low loss suspension for increased bass response and the SD-1 motor system for less intermodulation distortion. Very rigid cast frame, large windows.
We recommend a 2.5 cubic foot enclosure with a 3" diameter vent by 10" long, the F3 would be about 29Hz.
