Beam-steering loudspeakers
SC-90
90-channel column — full control from 350 Hz.
The largest S-Series column: 90 individually amplified transducers in a 1,290 mm cabinet. Vertical control from 350 Hz, four beams, and particularly effective mounted horizontally across wide spaces.
US list price. Project and regional pricing through distributors.
- 90 transducers — the same channel count as the SQ-90 in a column format
- Vertical control from 350 Hz for long throws and reverberant rooms
- Very effective in horizontal alignment across platforms and concourses

The SC-90 carries the SQ-90’s ninety channels in a column: 81 high-frequency and 9 mid-range drivers, each with its own amplifier and processing, controlling the vertical pattern from 350 Hz. Mounted horizontally it becomes a very wide, very shallow source — the configuration used across Sydney Central Station’s platforms to keep announcements intelligible on one platform and quiet on the next.
