I am really sorry to have to sell these but my current studio space is too small to accommodate them. The cabinets have some cosmetic scratches but they operate perfectly.The speakers have had one previous owner and were fully serviced by ATC in April 2015. They come with custom built stands and covers (not shown).If you want to hear them I currently have them in a studio in Whitstable in Kent and would happily give a demonstration.I can deliver using a personal courier to anywhere in England or Wales for £175 or they can be collected from Whitstable in Kent. If you are in Scotland or Europe I can calculate an exact cost for delivery depending on location.OverviewThe SCM100 ASL (active) are designed to perform at their best with the finest quality hi-fi equipment.Like their smaller brother, the SCM50 ASL, the monitors’ ability to reproduce music and speech with phenomenal accuracy, transparency and dynamics lies mainly in the SM75-150S soft dome midrange driver. However, recent modifications that include an upgraded tweeter and enhanced port profile have brought about further improvements in all performance parameters.Bass performance is equally impressive, thanks to ATC’s 12″ professional level bass driver that incorporates the company’s unique Super Linear Magnet technology. Bass, mid and HF drive units in the active model have their own dedicated and individually matched MOS-FET amplifiers.ATC’s active crossover network consists of a wide band-width, electronically balanced input stage with high common mode rejection and very low distortion.In passive form, the SCM100 SL provides broad and symmetrical dispersion, excellent amplitude and phase characteristics throughout the audio frequency range.SCM100ASL (Active)Drivers: HF 25mm Mid 75mm LF 314mm Super LinearAmplitude Linearity ±2dB: 65Hz – 17kHzFrequency Response -6dB: 32Hz & 22kHzMatched Response: ±0.5dBDispersion: ±80° Coherent Horizontal ±10° Coherent VerticalMax continuous SPL @1m: 115dB SPLCrossover Frequency: 380Hz & 3.5kHzInput Connector: XLRInput Sensitivity: 1VInput Impedance: >10k ohms balanced XLRAmplifier Output: HF 50 Watts RMS MF 100 Watts RMS LF 200 Watts RMSOverload Protection: LDR tweeter protection, plus active FET MGR (amplifiers)Power Requirements: Voltage: 100, 115, 230 (factory set)Frequency: 50/60HzPower: Nominal 90 Watts, Driven 350 WattsCabinet Dimensions(HxWxD): 834 x 400 x 585mm including amps (stands add 200mm to height)Weight: 64.8kg
