*): add additional 1,9 L for woofer!
**): calculate and add volume displacement of port(s)
formula: outer diameter [dm] square times 3,14 devided by 4, times length [dm]
ports should be rounded (aeroports)! In cases where round tubes don't fit,
channels with same cross-section (rounded at both ends) may be built.
damping: sealed encl. Fill loosely with poly-padding, vented encl.: 2 walls covered by acoustic foam.
enclosure wall thickness: MDF/Multilayer: 19 to 22 mm. Woofer screwed by metric thread knock-in nuts.
Subsonic-Filter: high pass filter of 3rd order or higher
mounting size:
mounting hole diameter: 183 mm
mounting depth: 111 mm
magnet diameter: 134 mm
recomm. freeplay behind magnet: > 20 mm
if flange gets lowered into baffle: without - with rubber gasket
grinding diameter: 206 mm 212 mm
grinding depth: 14 mm 16 mm
