Test Bench Article

Low Qts for outstanding performance in around 3 cf3 vented (please see below for some Madisound suggestions) for natural deep bass well below 30 Hz. Extra-sturdy die-cast aluminium chassis.

The 32W/4878T00 is the most powerful sub woofer designed by Scan-speak to this date, with its large 3” voice coil, extreme linear excursion and low resonance frequency, it is perfect to reproduce the deepest frequencies. It features a brand new type of paper-sandwich cone with a special foam filling technology (patented) that gives the cone very high stiffness and relative low weight. The motor system has heavy duty copper sleeves for optimizing eddy currents and minimizing self-induction. 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.

• Paper sandwich cone with Patented foam filling
• Patented Symmetrical Drive motor
• Spider with balanced woven in tinsel leads
• Extreme linear excursion (+/-14 mm)
• 3” Voice coil, Titanium former and paper reinforced
• Stiff and strong die cast aluminium chassis

Some boxes to try:

• 1.5 cubic foot sealed box has F3 of 45Hz. 
• 3.5 cubic feet with a 4" diameter vent by 12" long for F3 of 26Hz
• 2.75 cubic feet with 3" diameter vent by 12" long for F3 of 29Hz.  With this vent diameter you will run into air vent velocity trouble after 200 watts.  At 200 watts you are at 112dB.  A wider vent is too long.
