HORIZONTAL COVERAGE IN DIRECTIONAL MODE (100 HZ) VERTICAL COVERAGE IN DIRECTIONAL MODE (100 HZ)
IMPORTANT
So that directional behaviour and acoustic load are not altered, no reflecting surface
should be at less than 50cm (20”) from the RS15 side walls and drivers.
In case of stereo configurations, NEXO recommends that speaker side is set outwards to minimize
interference region in stereo designs (ie “RS15s LEFT” should be installed Left and “RS15s RIGHT”
should be installed Right).
8.2.2 RS15s pair
There are three ways of using pairs of RS15s in directional mode: “one side”, “back to back” and “face
to face” (50cm / 20” between grids)
“BACK TO BACK“ CONFIGURATION “FACE TO FACE“ CONFIGURATION
All of these configurations have symmetrical patterns with a smooth 15dB attenuation at the rear over
the entire RS15 bandwidth, but significantly different horizontal coverage.
-
“back to back” configuration has a -3dB coverage which decreases from 120° at 31.5 Hz
to 60° at 100Hz;
-
“face to face” configuration has a -3 dB coverage which increases from 120° at 31.5 Hz to
180° at 100 Hz.
Detailed coverage information on these configurations is available in section 9.3.2 of this manual.
