It features a paper-sandwich cone with very high stiffness and relative low weight. The motor system has heavy duty copper sleeves for optimizing eddy currents and minimizing self-induction.

Paper sandwich cone
Spider with balanced tinsel leads
3” Voice coil, Titanium former and paper reinforced
Patented Symmetrical Drive motor
Extreme linear excursion (+/-14 mm)
Stiff and strong die cast aluminium chassis
Suggested Box Alignments:
1.5 cubic feet sealed box for 3dB down of 48Hz and 6dB down of 32Hz
3.0 cubic feet with 3" vent by 13" long for 3dB down of about 22Hz
2.75 cubic feet with 3" vent by 15" long for f3 of 23Hz
2.5 cubic feet wtih 3" vent by 17" long for f3 of 25Hz
The sealed box used with a plate amplifier with bass boost might be a nice little subwoofer. The port length on the vented boxes is pretty long. Be sure you leave at least 3" to the back wall, preferably more.
