12-inch 60L Subwoofer

These 60ltr sub-woofers were built to complement my 2-way speakers "VoXDeuX". The drivers are 12" polycones with a free air resonance of 25 Hz. In the box they go down to 31 Hz where they are very active. The drivers are very efficient and are being powered by a compact 50W Class-D amplifier. A stereo feed is taken from the preamp and passed through an electronic filter. The filter has a -3 dB point of 52 Hz and but employs only a -12 dB slope. The internals of the box comprise of six vertical braces. Bitumanised heavy Aluminum foil covers most surfaces. Pockets and chambers are formed at the rear by the bracing which carries additional dampening. These are then covered by a single layer of damping.
