ATC SCM50 speakers enter What Hi-Fi? Hall of Fame 2026

A Hall of Fame honour for the reference pair

What Hi-Fi? has inducted the ATC SCM50 into its Hall of Fame for 2026, according to the publication. The honour goes each year to a single product that stands out in its category and price band, matches the magazine's performance-per-pound ethos, and can stand the test of time.

The choice was made as What Hi-Fi? celebrates its 50th anniversary this year. The publication says there was only one product that felt right for the honour, given the speakers' long service in its test rooms.

Two decades as the reference set-up

The SCM50 has served as the magazine's reference stereo speaker for the best part of two decades. In that time the pair has been paired with hundreds of components, from budget microsystems to very expensive pre/power amplifiers, and the reviewers say they have never let them down.

A reference speaker needs to act as a transparent window on the sources and amplifiers under test. According to What Hi-Fi?, the ATCs are honest and even-handed, adding no significant twist to the signal they receive.

The speakers are rated at 85dB/W/m, so they are not especially sensitive, though they are not a difficult load either. Even modest amplifiers can drive them to decent, if not ear-splitting, volume levels.

In-house drive units and careful evolution

All three drive units in the SCM50 are designed and built in-house by ATC. The company's background is in the professional studio world, where reliability and high power handling are essential, and its engineers prize low distortion and dynamic ability. Units go into production only once every requirement has been met.

The design has been carefully evolved over the years, and the current version costs £11,950 per pair. A 23cm woofer with a stiff fibre and resin composite cone handles the lows, tuned by a large front-facing port.

How the SCM50 sounds

What Hi-Fi? describes the sound in one word: honest. The speakers do not add treble sparkle or bass thump to make recordings more exciting, and they are not fussy about musical genre. The reviewers note they have the dynamic punch to handle Tchaikovsky's 1812 Overture and never sound fazed, even when pushed hard.

There is plenty of low-frequency authority too, with a solid, meaty presentation when required. The speakers are even-handed tonally and image well with a little care over placement. In the magazine's test room they sound best well away from the rear and side walls, angled slightly towards the listening seat, with the offset tweeters positioned on the inside to firm up focus.

The SCM50 digs up plenty of detail, from nuance in vocal delivery to the texture of a bass line, and presents it naturally and without forcing. Rivals, usually pricier ones, sometimes beat it on outright resolution, openness, imaging or rhythmic precision, but the reviewers say they have found nothing as satisfying an all-rounder or as practical a day-to-day review tool.

Why the honour matters

The SCM50 was originally introduced in the mid-Eighties, so its continued relevance is a notable achievement. As What Hi-Fi? puts it, great engineering does not date.

The induction ties in with the publication's 50th anniversary celebrations, and the magazine frames it as fitting recognition for speakers that have served it through thick and thin for a large chunk of that time. Readers considering a serious stereo pair should note the price has risen considerably from the design's origins, but the publication's verdict is that the all-round ability remains hard to match.
