SCM20PT

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 2^nd 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.
