Description
SCM20ASL Standard Edition
The SCM20ASL is a 2-way active stand-mount loudspeaker and is the ideal choice in modestly sized rooms where outstanding musical reproduction is the goal.
Its sealed cabinet design ensures exceptionally well controlled bass, even in smaller spaces and/or when located close to walls.
Driver Units
The bass driver, HF driver and amplifier are all designed and manufactured in-house by ATC and to the highest standards to form a system that cannot be matched by equivalent passive systems.
The bass driver is a 150 mm part with large 75 mm voice coil and short-coil (long-gap) motor assembly featuring ATC’s proprietary ‘SL’ motor technology which, reduces distortion in the upper bass
and mid-range.
High frequency reproduction is handled by an ATC 25 mm soft-dome part featuring a dual-suspension and very high energy 2.1 tesla motor.
Crossover
Integrating the two drive units is a precision active crossover which feeds a pair of class A/B MOSFET
power amplifiers. The crossover operates at line-level maximising efficiency, plus the inclusion of an all- pass-filter results in improved timing and tonal balance through the crossover region.
Active Amplification
One power amplifier is dedicated to each drive unit and their performance and power output is carefully tailored to the driver demands and the musical elements they reproduce.
The SCM20ASL Standard Edition cabinet features a combination of bracing for stiffness and damping to suppress resonance and is available in a wide range of real wood veneers, satin black or white painted finishes and high gloss lacquers.
