Reluctant sale of my ATC SCM 40 V2 White Satin speaker. I have bought them in August 2017 brand new from Audioemotions. Still more than 4 years of warranty left. There were specially pre-ordered from the manufacturer by the shop so there are very recent build (not ex demo or used!!!) They been very well looked after and they are like in brand new condition, no marks or any signs of use. They been played not that many hours. I have all the boxes and books with warranty etc. These are seriously good speakers. There were a big step up from SCM19 for me. Scale and dynamics are on different level and the famous ATC Soft Dome mid-range driver brought new level of realism and accuracy. Just brilliant! . Overview New ATC designed and built 25mm soft dome HF unit with precision alloy wave guide.. ATC 164mm bass driver. Massive optimised motor assembly. ATC Soft Dome mid-range driver. Flat impedance curve allowing easy load for amplifiers. “Given a serious source and recording the new ATC SCM40 is superb – I know of no price rivals that give this level of accuracy, speed and insight…it’s capable of a level of transparency you normally only expect from loudspeakers at three or four times its price.” Hi-Fi Choice, October 2014 Postage Collection from Oxford would be much appreciated. I can also meet in 40 miles radius or around Coventry. posting via courier is possible they are quite heavy - each weights 31kg. So cost will be high. Please contact me if you have any questions.

So I sold my KEF Reference Model 2.2s. I now have to decide what to replace them with and am leaning towards ATC SCM40s. My concern is that they might need a mighty amp to get the best from them. I'd initially have them running passive bi-amped and probably convert it to an active set up using the same hardware, possibly with an extra 2 channel power amp to go three way, possibly not. I have a slightly unusual amp. It's a Primare SPA21 surround amp which has been modified and upgraded by a rather talented tech and I use basically as an analogue four channel power amp. I only have test figures for it with one channel driven but as it has 100,000 uF of power caps and 1600W of toroidals I'm reasonably confident it won't slump too much with four channels driven. Test figures for one channel are: Test: 7 of 10, EIA RS490/ CEA490A Channel: FRONT L Target: 1.0000 %THD+N Actual: 1.0044 %THD+N Input: 2.208 V, 1000 Hz, sine Output: 35.31 V, 1000 Hz Gain: 24.1 dB Load: 8.0 Ohms Power: 156 W Test: 8 of 10, EIA RS490/ CEA490A Channel: FRONT L Target: 1.0000 %THD+N Actual: 0.9951 %THD+N Input: 2.075 V, 1000 Hz, sine Output: 32.91 V, 1000 Hz Gain: 24.0 dB Load: 4.0 Ohms Power: 271 W Do we think it can handle the SCM40s or should I shelve my plans until I can afford a Bryston or something to go with?
Hi All, My speakers are ATC SCM40 passive old style. My power amp is an ATC SPA2-150 and the pre is an MFA Baby Reference. I am considering going to active speakers and, as I like the ATC presentation, I am considering their SCM20ASL towers. Unfortunately my room is too small to accommodate the larger 50s being 13 feet by 11 feet. The speakers have to face across the 11 feet, something that the 40s manage quite well. One of the things that concerns me is that the 40s are a three way design but the 20s are two way. Given that the 20s use the new tweeter and the SL bass driver I would welcome any comments/advice on whether they will improve on my 40s with the ATC SPA2-150. If the consensus is that they would be an improvement I would also be grateful for views on their compatibility with my MFA pre. Thanks
