Comprising a 15" transducer with a frequency response of 35Hz - 200Hz in omni or 35Hz- 150Hz in directional mode and a sensitivity of 105db SPL, the RS 15 offers versatility for installations and touring requirements.
The RS15 offers directive subwoofer coverage from a standard bass reflex subwoofer architecture. Simply turning the cabinet vertically or horizontally will change its characteristics from omni to cardioid.
Digital signal processing, via NX242 TDcontrollers, allows the RS15 to display precise cardioid pattern control through the DSP-processed correlation of acoustic distances between transducer and vent sources. These sources are linearly positioned in the output direction of the cardioid pattern. The RS15 sub does not face the same direction in omni and cardio mode. In cardioid mode, the sidewalls of the RS15 (where the rigging system is attached) behave as the cabinet's front and rear face. As such, the RS15's cardioid LF and VLF energy propagates from only one end of the enclosure, rather than from the front face. This behaviour is maintained regardless of whether speaker cones are positioned on the side or top. The RS15's cardioid pattern reduces rear levels by 15-18dB, minimising rear/side wall reflections.
Designed in tandem with Nexo's new Geo S12 Series of loudspeakers, the RS15 also applies across the entire Nexo product line, and can be deployed in nearly any sub-hire rental. It will be paired with Nexo's NX242 digital TDcontroller or with the S12 TDcontroller, which provides analogue LF processing to yield a traditional omni-directional (cone-forward) LF and VLF pattern control and performance.
