ATC SCM150 - PAIR

ATC SCM150 – the floor standing loudspeaker from the Classic Series

SCM150 by ATC – Acoustic Transducer Company – are the reference model of the Classic Series 3-way floorstanding loudspeakers with stands, available in the passive SCM150 SL or active SCM150 ASL version. This large-sized model is one of the spearheads in the English brand's portfolio: all the components are handmade and represent the best of driver and electronic technology available on the market today.

The 25mm soft dome tweeter benefits from a unique doped polyester double suspension design, which adds a secondary suspension to provide greater linearity and suppress unwanted oscillation modes, promoting greater control.

The monitors ability to reproduce music and speech with phenomenal clarity, detail and dynamics lies primarily in the 75mm soft dome midrange.

The performance of the 375mm woofer with a large 75mm voice coil and powerful short-coil motor is equally impressive. This driver features ATC's SL – Super Linear – technology which drastically reduces the distortion typical of moving-winding drivers by 12-15dB (third harmonic).

In the passive version – SCM150 SL – the second order crossover uses oversized air chokes to handle two crossing points at 380Hz and 3.5kHz.

To get the right control, we recommend the SIA2-150 integrated amplifier or the P2 power amplifier of the same brand. For those looking for dynamics, musicality and detail, we recommend the H590 integrated amplifier, or the two classic Hegel P30A and H30A chassis.

In the active version – SCM150 ASL – instead, the active analog crossover consists of an electronically balanced input stage, characterized by a high bandwidth and a very high common mode rejection. Connection is via XLR only, as befits a speaker that comes from the studio world.

The ideal combination is with the extraordinary preamplifiers of ATC itself: CA2, CDA2 or the top of the range SCA2. Alternatively, Chord Electronics electronics can surprise for the level of detail and sharpness offered thanks to the famous proprietary technologies integrated in their DACs. The ideal combination is with the Hugo TT2 and Dave DACs, or with the stand-alone Prima and Ultima Pre 3 preamplifiers. As an alternative, we recommend Hegel electronics, in particular the P30A reference preamplifier or the smaller P20.

The audio signal is managed by 3 dedicated MOSFET amplifier modules, one for each driver: 50W for the tweeter, 100W for the midrange and 200W for the woofer, for a total of 350W. In this way, the loudspeaker is able to reproduce the sound in an even more detailed and precise way, without any distortion or loss of quality.

In line with the qualities of this extraordinary loudspeaker, we recommend cables from the Sarum T line by Chord Company, with a typically transparent and analytic timbre, capable of excellent signal transmission quality and excellent interference shielding.

Design

Derived from the studio range, the ATC SCM150 loudspeakers have been developed to provide accurate and natural sound, without any coloration or distortion. This makes them ideal for faithfully reproducing any type of music, from classical to rock, jazz, pop and more.

Thanks to advanced design technologies, the SCM150 loudspeakers are able to reproduce an extremely precise and detailed sound, with an extremely wide frequency response and a great power handling capacity.

The cabinet is massive, solid and inert, and integrates bitumen damping placed at critical points to minimize cabinet response.

The speakers are supplied with 20cm stands and fabric covered grilles.
