The ATC SCM20ASL Limited Edition 2-way active stand-mount with the limited edition C4 MK2 subwoofer continues ATC’s philosophy of combining the best in-house loudspeaker drive units with matched on-board active amplification for optimal fidelity.
These new models integrates a 2-way active system, previously only available in a floor standing model, into a smaller stand-mount cabinet. The SCM20ASL Limited Edition features ATC’s proprietary 150mm/6” ‘Super Linear’ Mid/Bass driver paired with a 25mm/1” ‘S-Spec’ dual-suspension tweeter. Partnering the SCM20ASL loudspeakers is a sonically matched limited edition C4 Sub Mk2 Subwoofer.
Limited to just 150 pairs, the 2-way active stand-mount and the limited edition C4 MK2 subwoofer design is finished in a stunning high gloss lacquer in the ATC company dark blue.
Complementing the cabinet, the front baffle is hand-upholstered in royal blue full-grain Napa leather by German leather specialists Eissmann. The exterior alloy components feature a silver anodised finish in striking contrast to the blue lacquer and leather of the cabinet and baffle.

The bass driver operates in a 20-litre sealed cabinet and power is provided by on-board class A/B MOSFET power amplifiers, capable of delivering 200W and 50W continuous power to the bass and HF drivers respectively. The loudspeaker crossovers are active, analogue 2nd order Linkwitz-Riley and an all-pass filter is included to optimise the phase response through the crossover region, resulting in far improved tonal balance and imaging.
Input to the loudspeaker is via balanced XLR, located on the rear panel and there are user controls for input sensitivity and low frequency shelf cut/boost. The input sensitivity control allows the user to tailor the input gain to suit their source/pre-amplifier combination, resulting in more consistent performance. The low frequency shelf control gives the user the option to subtly adjust the bass response to suit their room and/or their personal taste. The speaker is supplied with a removable grille, wrapped in dark blue acoustically transparent cloth.
Only 150 pairs of the SCM20ASL LE and 20 partnering C4 Sub Mk2 subs will be manufactured
UK stock allocation is limited to just 10 pairs. (we have secured just three pairs)

Testimonials
Bought some Rega Kyte speakers, stands and chords from DB online and they were incredibly helpful. They updated my delivery address very quickly and recommended a longer cut of cables which they did complimentary. They also noticed I didn’t order with banana plugs so called me back to double check, which I did mean to order. When i had some issues connecting my cables and speakers, I called for some advice which they happily gave. Excellent service and next day delivery to London. Thoroughly recommend.

Probably one of the best companies in the world. They had to special order in the speakers which took a fair bit of time, which is totally understandable, but they kept in touch with me throughout the entire time with updates (even on a Sunday!!!) and once the speakers were with them, they were dispatched and arrived next day.
The entire sound system that I purchased is insanely good, but still not as good as Doug Brady HiFi!

I have recently purchased a HiFi package with Doug Brady and I could not be more thrilled with my experience with them.
When I walked into the store, I was made to feel welcome and was introduced to some of the products. I produces a list of specific items I was interested in and John was really helpful in showing me these items. He set the system up so I could experience it, he made some suggestions which made the package even better. Nothing seemed too much trouble for him, he was very knowledgeable about the products and gave great advice. I didn't feel pressured to buy anything, or didn't feel that he was upselling at any point. I left with an amazing package and I'd like to thank John and the team for the fantastic experience.
