search for the ultimate loudspeaker is finally over - or so
said Westalke in 1989.
5-way SM-1 is a professional studio monitor with dedicated external
crossovers. Each Tower SM-1 weighs 450kg - your audiophile Atacama
stands won't do.
Three versions were made available:
SM-1F (variant of the above)
SM-1VF (vertical, left)
SM-1VT (or Tower
SM-1 uses three separate compression drivers for the mid, high and
ultra-high frequency bands. The lower frequencies are reproduced
by two 18" woofers and the all important midbass frequencies
are sung by a 12" polygraphite 14-kilogauss driver sealed in
its own sub-cabinet. The SM-1 is natually heavily dampened and braced.
or passive crossover configurations are possible with either the
MRX-2 or SM-1X
dedicated units. The MRX-2 is of the
two-way active kind, with passive internal filters ; the SM-1X
is a four-way active unit, with bi-wiring available for the high
and low frequency inputs to go quad-amplification. The two units
used in conjunction allow for pent-amplification !
veneers were walnut, oak or black satin ; optional colors rosewood,
high-gloss black or high-gloss white - rosewood would do for me.
Tower SM-1 is still available from Westlake
Audio and so are the SM-1VF,
the original SM-1
(all with upgraded power input capabilities), and the two external
crossovers - good things last forever.
