ATC SCM100SE 3 way active loudspeaker


What we Say:

The ATC SCM100SE sits at the top of the ATC range. It takes the SCM100ASLT and moves the performance on significantly. It does this by using a stiffer multi-layer curved cabinet, improved drive units and also improved amplifier packs. There are three models in the range, the SCM50SE, SCM100SE and SCM150SE.

It will fill even the largest room with ease without any sign of strain. It is a large 3 way floor standing design. The cabinet is available in a range of exotic veneers and both matt and gloss finishes. The brow features can be specified from a range of options.

The amplifier packs in the SE product range are fully discreet without any integrated circuits. They sit inside the rear of the cabinet and cooling vents are located on the top rear of the cabinet. The attention to detail on the cabinets and grills is to an exquisite standard.

The ATC SCM100SE  amplifier pack has three channels. The bass channel is 200W, mid channel is 100W and treble has 50W. Whilst these may not sound that large this power is on tap direct to the drivers with no passive crossover sat in between wasting power. This gives the SCM100SE explosive dynamics unlike any other loudspeaker you will have previously heard.

What they say:

The SE Series is the latest statement in a long line of Limited Edition pr oducts that encapsulate
the very best of ATC’s engineering and design values.
The Company’s preoccupation with a performance-first philosophy and attention to engineering
detail defines and enhances the visual design pr oducing distinctive, elegant and unique
limited edition loudspeakers.
The SE Series is available as either passive or active.
Passive SEs require a separate power amplifier and the passive crossover is designed to provide
an easy amplifier load and excellent performance.
The perfect power amplifier to partner the passive SE Series is the ATC model P2
Dual Mono Power Amplifier providing a comfortable 300 watts per channel.
special edition series
Active SEs on the other hand, include a tri-amplifier incorporating a separate full y discrete amplifier
for each drive unit and active crossover filters with phase correction ensuring exceptional linearity
and therefore very low distortion. In short the best performance money can buy.
Manufactured and designed in house ATC drive units are legendary for their innovation and performance.
The SE Series use only ATC drive units. The unique soft dome, the SM75-150S first produced in 1976,
was revolutionary at the time and remains to this day a benchmark for midrange drive unit performance.
It is now complemented by a new high frequency soft dome, the SH25-76S, built to the same exacting standards
that also sets a new benchmark for HF reproduction. The bass drivers all have short coil in a long magnetic gap
and incorporate ATC’s super linear magnet technology for maximized linearity and power handling.
Built to give a lifetime of service, performance and musical pleasure, all ATC products carry a six year warranty.
