Technics SB-M3

More domestic version of the gargantuesque SB-M1 which previsibly sold a little better... but not much at any rate : the SB-M3 is quite, quite rare.

The filter comprises low distortion choke coils, high-impedance wires, electrolytic and film caps and steep 18dB/octave slopes ; the cabinet is made of real wood (unlike that of the the SB-M5) and uses special internal joints to prevent resonances.

33cm Bass
1,5kg magnet with linear damper and 4-layer voice-coil

8cm Mid
GFRP voice-coil with copper-clad aluminium wire and 950g magnet

2,8cm High
laminated mica diaphragm ; 35Khz response with magnetic fluid ;
18,000Gauss with square magnet for closer mounting to mid driver for more coherent dispersion.

I don't understand why, really, none of these sold better... but then, the present NEXT flat panels don't seem to sell well either.
