ATC SCM40AT ACTIVE Floorstanding loudspeakers - Tri Amplified
What Hi-Fi have reviewed the new SCM40A as part of their monthly ‘Temptations’ feature. Here is a little of what they had to say:
“these ATCs… take all in their stride, revealing a lovely cohesion throughout the frequency range. Resolution, timing and dynamics are all spot-on… factor in the built-in amplification, exotically engineered in-house drive units and the resultant exceptional sound quality, and the SCM40As emerge as something of a high-end bargain. Consider us smitten.” What Hi-Fi"
“The mid range is the money zone in speakers, and never is this truer than with the SCM40As. The soft dome is a revelation, especially with acoustic guitars. The romantic Mexican string style in “Puesta Del Sol” by Sean Harkness combines mellow richness with clarity. This accuracy is a hallmark of ATC.”
“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.”
“… 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.”
The SCM40A utilises ATC’s remarkable soft dome dual-suspension SH25-76 tweeter together with the company’s signature 75mm soft dome mid-range and a 164mm short coil/long gap (under-hung) bass unit. The drivers are powered individually by a proprietary ATC tri-amplifier pack.
Amplifier Power comes in a Tri Amplifier configuration utilising a discrete MOSFET, class AB three-channel amplifier uses ATC’s Grounded Source output stage to deliver 32W to the HF driver, 60W to mid and 150W to the bass driver for a total of 235 watts continuous power. Input is via balanced XLR.
