It's Like Adding Three Monoblock Amps to Your Loudspeaker: ATC SCM40a Active Floorstander Plays with Iron-Fisted Control, Sublime Delicacy, Supreme Resolution

What happens if you add tri-amplification to the ATC SCM40 v2, one of the most accurate, insightful floor-standing loudspeakers made in its class? Jaws drop. Hips move. Toes tap. Senses awaken. Music playback becomes real in ways you never thought possible in your home. Providing 150W to the woofer, 60W to the midrange, and 32W to the tweeter, ATC's in-house-made amplifiers turn the SCM40a active tower loudspeakers into world-beating instruments that give you ultimate convenience (just add a preamp and source) and borderline-magical sonics.

The powered version of SCM40 v2, SCM40a further improves on its sibling by both lessening what's required to drive it – and providing you everything you need right in the speaker. SCM40a offers both iron-fisted control when required but also plays with delicacy when situations call for it. And it gets better: ATC inserts the Class A/B amplifiers after the crossover, eliminating any need for a sound-degrading filter network between the amp and drivers. The result: Immensely increased power as well as in-the-moment immediacy, palpable solidity, and self-assured grip. This all comes on top of award-winning performance.

How revealing and see-through clear are the sonorously musical SCM40a? Enough that we think they should actually come with a warning informing listeners that they're about to expose so much detail, information, texture, and depth from their recordings, that they might change their opinions on the production on some of their most beloved recordings. Benefitting from in-house-made tweeters, 75mm soft-dome midrange drivers, and 164mm bass drivers exclusive to ATC designs, the staggeringly insightful SCM40a plays with wall-to-wall openness and pinpoint precision.

If it's in the recording, SCM40a will lay it out on a tremendously wide soundstage. All the good, and, if it's there, anything else. They're that special. Boasting reference-setting coherency and seamless integration between the driver and midrange, these tremendously powerful instruments also deliver prodigious bass and astonishing attack. Backed by a six-year manufacturer's warranty, tower loudspeakers in this price range don't come any more transparent or confident.

"If you’re tired of the cable and equipment hassle, I can’t suggest a better pair of active speakers than the ATC SCM40as. They produce sound well beyond what their price tag suggests, especially considering that you will eliminate at least a few thousand dollars in speaker cables and power amplifiers."
--Jeff Dorgay, TONEAudio

"If you want a pair of speakers that play really loudly without turning hard or edgy these would be an excellent choice. At higher levels their punch is deeply impressive, as is their depth and power at low frequencies. Consider us smitten."
—What Hi-Fi?, five-star review

"The ATCs are full bandwidth speakers that have grip in the bottom end and a total absence of ventilation on the cabinet. The bass is deep, solid and, thanks to the active operation, tactile. It has a degree of solidity that makes everything feel like it’s in the room, that and the ability to play at the sort of level that approaches that of live sound you get in a studio control room."

Focused on applying supreme engineering to proven audio principles, the tradition-minded British company produces English-made speakers revered for their revealing nature, astonishing clarity, and exceptional balance.
