SCM20ASLT
Overview
The SCM20SL Tower is ATC’s flagship 2-way floor-standing loudspeaker
and is the ideal choice in modestly sized rooms, but where performance
cannot be compromised.
Its sealed cabinet design ensures excellent timing, useful low
frequency output below the cut-off and that the speakers can be placed
relatively close to walls without excessive low frequency ‘boom’.
Both the mid-bass driver and tweeter are handmade by ATC. The bass
driver is a 6”/150mm part with huge 3”/75mm voice coil and massive,
long-gap (short-coil) motor assembly featuring ATC’s proprietary ‘SL’
motor technology. The tweeter is a 1”/25mm soft-dome part featuring a
dual-suspension and very high energy 2.1 tesla motor. Together, they
form the basis for an exceptional 2-way monitor loudspeaker capable of
delivering outstanding resolution and musicality.
Driver integration withing the passive model is handled 2nd
order crossover featuring oversize air-core inductors which are would
in-house by ATC. Capacitors are all high voltage polypropylene film
types and the input features heavy duty binding posts in a bi-wire
configuration.
The SCM20 cabinet is constructed to be heavy and inert, with
bitumastic damping panels deployed at critical positions to minimise
cabinet colouration. The cabinets are available in 10 different hand
selected veneers; satin black/white painted finishes and also
piano/white high gloss polyester.
