Bass
96/100
Reviewers repeatedly praise deep, well-controlled extension and authority (32Hz -6dB free-field spec). Large 314mm woofer in a 100-litre cabinet yields effortless, room-filling bass and strong low-end slam; comments include 'huge low end extension', 'deep, beautifully controlled bass grunt' and 'move air properly'.
Mid
94/100
Multiple reviews highlight a revealing, highly linear midrange with ATC's large soft-dome mid and short-coil/long-gap topology. Descriptions include 'revealing midrange', 'clarity of the midrange' and 'neutral, resolving' presentation, indicating excellent timbre and presence.
Treble
91/100
Tweeter and machined waveguide provide precise dispersion and detail; reviewers note strong extension and air but also that bright or poor recordings can sound abrasive. Well controlled and detailed, with occasional harshness revealed on edgy material.
Soundstage Imaging
93/100
Reports of a focused, precise soundstage with good width and depth and 'concert hall feel'. Toe-in tunes imaging and reviewers praised layering and stable image focus, producing a thrilling and realistic spatial presentation.
Dynamics
95/100
Described as having effortless dynamic envelope, strong macro- and micro-dynamics and the ability to play loud without strain. Reviewers emphasise 'absence of dynamic restraint', 'big slam' and robustness at significant levels.

Build Quality
94/100
Very substantial construction (≈79kg active), in-house drivers and discrete amplification; reviewers cite solid engineering, heavy duty cabinet and quality finishes. The active crossover and amps are derived from Anniversary models, underlining premium engineering.
Features Connectivity
86/100
Fully active design with three-channel amplification, onboard active filters and XLR input. Reviewers note the requirement for a quality preamplifier (balanced XLR) and praise the integrated amps; no DSP/app streaming, but that's expected for this class.
Value for Money
88/100
At the listed high price reviewers nevertheless called the SCM100SE 'an awful lot of phenomenal speaker for the money' and 'not excessive' relative to peers. Exceptional performance supports strong value for buyers who can afford this level.
