Pdf specification sheet for download.

The 32W/4878T01 is a very powerful 28cm woofer, with its large 3” voice coil, low resonance frequency. 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.

Key Features:

Paper sandwich cone
Spider with balanced tinsel leads
3” Voice coil, Titanium former and paper reinforced
Patented Symmetrical Drive motor
Linear excursion (+/- 7 mm)
Stiff and strong die cast aluminium chassis

Suggested Box Alignments:

1.5 cubic feet sealed box for 3dB down of 65Hz and 6dB down of 45Hz
2.0 cubic feet with 3" vent by 9.5" long for 3dB down of about 39Hz
2.5 cubic feet with 3" vent by 9" long for f3 of 38Hz
2.75 cubic feet with 3" vent by 8" long for f3 of 37Hz
3.0 cubif feet with 3" vent by 7" long for f3 of 35Hz

Shortening the vents by a few inches will lower the f3 by 3-5Hz, but the longer port might sound more natural.
