The Revelator woofers and subwoofers feature very rigid cones in paper or aluminium that operate as a piston over a wide frequency range, in combination with Scan-Speak's low-loss linear suspension and the patented Symmetrical Drive (SD-1) results in very low distortion and a smooth and well behaved frequency response as well as perfect transient reproduction.The 32W/4878T01 is a very powerful 32cm 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.

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 cubic 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.
