IMPORTANT
So that directional behaviour and acoustic load are not altered, no reflecting surface
should be at less than 50cm (20”) from the RS18 side walls and drivers.
In case of stereo configurations, NEXO recommends that speaker side is set outwards to minimize
interference region in stereo designs.
7.2.2 RS18s pair
There are three ways of using pairs of RS18s in directional mode: “one side”, “back to back” and “face
to face” (50cm / 20” between grids)
All of these configurations have symmetrical patterns with a smooth 15dB attenuation at the rear over
the entire RS18 bandwidth, but significantly different horizontal coverage.
- “one side” configuration has a constant -3 dB coverage of 120° from 31.5 Hz to 80 Hz;
- “back to back” configuration has a -3dB coverage which decreases from 90° at 31.5 Hz to
60° at 80Hz;
- “face to face” configuration has a -3 dB coverage which increases from 90° at 31.5 Hz to
120° at 800 Hz.
