ATC SCM 150 ASLT LE: The new Limited Edition active loudspeaker system brings exceptional focus to a 45-year heritage of innovation and precision engineering

ATC loudspeaker Technology is proud to announce the availability of the SCM 150 ASLT LE, a luxurious marriage of world-class transducer and electronic design engineering.

This Limited Edition of just 22 pairs redefines music reproduction in the home. Exquisitely finished and offering true full range sound, the combination of world-class transducer and electronic design engineering delivers a staggering level of clarity, neutrality, transient response and power delivery that’s simply effortless.

The 3-way system comprises flawlessly engineered SCM150ASLT speaker towers incorporating the latest ATC designed and built drive unit technology, combined with an ATC P6 active power amplifier.  SCM150ASLT drivers including the new 25mm neodymium soft dome SH25-76S super dome tweeter, the 75mm soft dome SM75-150S super dome midrange and the SB75-375SL super linear bass driver are driven directly by the six dedicated channels of the P6 dual-mono, 3-way power amplifier, housed in an elliptical billet aluminium chassis, exquisitely machined and finished to complement the impeccable quality of the cabinets.

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, PVD treated to create an exclusive nickel-like appearance.

SCM150ASLT speaker
Deploying proprietary drivers throughout, the 3-way system uses ATC’s new 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 active 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 features 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 105 decibels 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.  Proprietary speaker cables are included with the system.

Price And Availability
As is customary with ATC products the SCM150ASLT and P6 are covered by a six-year warranty.Available to order immediately.  Product built to order, earliest shipping Wednesday August 5th.
