Nexo unveils Ray Sub technology

Comprised of a 15 inch transducer with a frequency response of 35 Hz – 200 Hz in omni or 35 Hz – 150 Hz in directional mode and a sensitivity of 105 dB SPL, the RS15 offers directive subwoofer coverage from a standard bass reflex subwoofer architecture.

Digital signal processing, via NX242 TDcontrollers, allows the RS15 to display 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 low frequency and very low frequency 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 – 18 dB.

The RS15 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 low frequency and very low frequency pattern.
