Here at Audio T Southampton, we have always been big fans of ATC speakers—especially their fantastic range of active models. In today’s blog, I’ll be diving into one of their most prestigious offerings: the illustrious SCM100ASLT SE. I’ll share my experience with these extraordinary speakers during the short time we had them. Without further ado, let’s jump in!

What Does “Active” Mean?

For those unfamiliar, ATC specialises in both passive and active speakers, with the latter featuring built-in amplifiers precisely matched to their drivers. Unlike passive speakers, where you need to consider wattage per channel carefully, active speakers remove that stress by integrating everything seamlessly. The only additional requirement is mains power for the built-in amplifiers.

The key benefits of active speakers include perfectly matched amps for each driver and the freedom to keep your rack uncluttered for other components, such as sources or streamers.

Massive Size, Balanced Sound

Unboxing these imposing speakers was a memorable experience. Standing at nearly 1.2 metres tall and weighing 79kg each, they’re as monumental as they are magnificent. Once positioned and fitted with spikes, it was clear these speakers were in a class of their own. The High Gloss Piano Black finish was flawless, and their sleek, distinctive "Brow" design added a touch of elegance.

a fantastic track to test both highs and lows!

To play these beauties, we paired them with the award-winning AURALiC Aries G2.2 and Vega G2.2, using the Vega to control the speakers. The sound was nothing short of breathtaking. The bass was tight, controlled, and effortlessly powerful, while the midrange remained crystal clear, and the highs were sweet and precise. Everything was perfectly balanced—an audio experience that was as immersive as it was impressive.

A Magician’s Dream

One standout quality of the SCM100ASLT SE is their ability to “disappear.” Let me explain: when we finally had the system set up, the team gathered to listen to a wide range of tracks. The first was Fanfare for the Common Man by the Minnesota Orchestra. The kettle drums boomed with such authority it felt like they shook the room. But as the trumpets entered, the speakers blended into the background, as if the sound was coming from nowhere.

Another track that left a lasting impression was Malia’s Celestial Echo. Known for its deep, rich bass, it’s a challenging song for many speakers. Yet the SCM100s handled it effortlessly, reproducing punchy, dynamic bass without breaking a sweat. It was as if the music was alive—simply astonishing.

Great on Paper, Better in the Flesh

A quick glance at the specs shows the SCM100s are built to amaze. Each speaker features three amplifiers—200W for the 314mm super-linear bass driver, 100W for the 75mm soft dome midrange, and 50W for the all-new 25mm soft dome tweeter. The cabinet is masterfully constructed, providing the stability needed for such precision. Together, these components create a speaker that reproduces sound with unparalleled clarity and depth.
