The System

Listening with

ATC SCM11 · Speakers: passive 2-way standmount (25 mm soft-dome HF, 150 mm CLD mid/bass)

Impedance: 8 Ω
Sensitivity: 85 dB @ 1 W / 1 m
Frequency response: 56 Hz – 22 kHz (-6 dB)
Connectors: bi-wire binding posts / 4 mm plugs
Recommended amplifier power: 75 – 300 W
Other: max SPL 108 dB; crossover 2.2 kHz; 381 x 232 x 236 mm; 10.9 kg

Matching notes: The SCM11 is rated at 85 dB (1 W / 1 m) into 8 Ω nominal. Burson rates the Timekeeper 3X GT at 110 W into 8 Ω and 180 W into 4 Ω. At that rating the speaker would reach about 105 dB SPL at 1 m (calc., one speaker, before room gain). ATC recommends 75 – 300 W amplifiers. ^{[1] [2] [3]}
