A shiny new ATC 150 active
Thursday, July 2, 2020

ATC have launched a luxury version of their largest domestic loudspeaker in the SCM150ASLT. The 3-way system comprises SCM150ASLT speaker towers incorporating the latest ATC designed and built drive unit technology, combined with an ATC P6 power amplifier. The driver includes the new 25mm neodymium soft dome SH25-76S super dome tweeter, a 75mm soft dome SM75-150S super dome midrange and the SB75-375SL super linear bass driver with each driven directly by the six channel P6 dual-mono, 3-way power amplifier, housed in an elliptical billet aluminium chassis. 

Manufactured to the highest standard by ATC’s own cabinet makers, weighing 116kg and at approximately 1.4m tall, each speaker enclosure is finished in selected European crown-cut walnut veneer with a high-gloss polyester lacquer, and detailed with a stainless steel badge, input panel and bespoke limited edition plinth, treated with PVD to create a nickel-like appearance.

SCM150ASLT drivers 
Deploying proprietary drivers throughout, the 3-way system uses an SH25-76S tweeter featuring both upper and lower suspension for greater operational precision and lower distortion; the latest evolution of ATC’s signature soft dome midrange design, the SM75-150S, and the company’s low-distortion SB75-375SL Super Linear bass driver. Combined they deliver a response accuracy of ±2dB between 60Hz-17kHz and ±6dB from 25Hz to 22kHz across a wide horizontal dispersion and at a maximum SPL of 117dB. The rear-mounted input panel features a single LEMO aerospace-grade 10-pin connector.

P6 power amplifier
The P6 is a high-performance Class AB dual-mono power amplifier designed and built by ATC to provide dedicated amplification and optimally matched active crossovers for the SCM150ASLT. It contains a total of 6 channels: 2x (200W LF, 100W MF, 50W HF) for a combined output power of 350W/side. Generating a signal-to-noise ratio of more than 105dB its ultra-low noise discrete design, paired with 3-way active crossovers with phase equalisation, offers clear and detailed audio reproduction. On the rear panel, professional L/R XLR inputs (from preamplifier/digital source) are joined by aerospace-grade LEMO multi-pin loudspeaker output connectors. 

Built to order the SCM150ASLT carries a £46,600 price tag and will be available for shipping in early August.
