ATC SCM40 Passive Loudspeaker Pair

Meet the Stunning ATC SCM40 Passive Speakers

Floorstanding Speakers delivering Precision, Authority and Musical Integrity 

When it comes to highfidelity loudspeakers that combine professionalgrade engineering with exceptional musical performance, the ATC SCM40 Passive Loudspeaker Pair stands out amongst the most respected in hifi today.

Built with the same acoustic principles that have made ATC legendary in both studio monitoring and home audio, the SCM40 Passive Speakers offer a level of transparency, depth and control that rewards close listening and keeps listeners coming back to familiar recordings with fresh insight. 

True ThreeWay Engineering for Balanced Sound

Using a true threeway driver configuration that dedicates separate transducers to high, mid and low frequencies they feature custombuilt ATC drivers including a 25mm softdome tweeter with precision alloy waveguide, a 75mm softdome midrange and a 164mm bass driver.  All work in harmony to deliver a smooth and coherent acoustic response from 48Hz to 22kHz. This careful division of labour ensures each frequency band is handled with clarity and authority, reducing distortion and enhancing detail.

Natural, Uncoloured Musicality

One of the many strengths of ATC loudspeakers is their neutral and truthful sound signature. Instead of colouring the music, the SCM40s drivers and crossover system focus on faithful reproduction so voices are lifelike, instruments have natural presence and dynamic contrasts feel real and engaging. This balanced performance makes the speakers equally capable with jazz, orchestral music, rock or electronic genres and particularly rewarding with highresolution recordings. 

Designed to Work with a Wide Range of Amplifiers

The ATC SCM40 Passive Loudspeakers flat impedance curve and efficient crossover allow it to pair well with a broad range of quality amplifiers. With a nominal impedance of 8ohm and a recommended power range from approximately 75W to 300W, these speakers deliver confident performance with both solidstate and tube amplification. 

They also reach a maximum sound pressure level (SPL) of around 112dB, giving them the ability to fill generous living rooms with detail and impact. 

A Thoughtful, LongTerm Investment

Constructed with meticulous attention to detail, the SCM40 benefits from ATCs decades of driver development and acoustic expertise. The rigid, welldamped cabinets and highquality crossover components contribute to low coloration and extended performance longevity.

Each pair is built to last and backed by a robust 6 year manufacturer warranty, reflecting ATCs commitment to reliability and durability.

About ATC

Founded in 1974 in the UK by Billy Woodman, ATC (Acoustic Transducer Company) is renowned for building some of the most accurate and dynamic loudspeakers in the world. Unlike many brands, ATC designs and manufactures its drive units entirely in-house, ensuring complete control over performance and consistency.

At the heart of many models is the legendary Soft Dome midrange driver, famous for its natural vocal reproduction and exceptionally low distortion. This clarity through the critical midband is why ATC loudspeakers are trusted in professional recording and mastering studios worldwide.

Available in both passive and fully active designs, ATC speakers prioritise neutrality, control and wide dynamic range. They are not voiced to flatter recordings they are engineered to reveal them.

Built in England and backed by a six-year warranty, ATC loudspeakers are designed to deliver decades of musical accuracy and enjoyment.
