The RS15 is the first offering of NEXO’s patent pending RAY SUB Technology. The RAY SUB Technology is based on optimizing positioning and phase relationships of radiating surfaces in vented enclosures, permitting acoustic distance from rear to front sections to always increase as frequency decreases; consequently rear and front sections sum up efficiently over the entire subwoofer bandwidth, allowing for an average of 5 db gain from the rear section in the forward direction and cancelling in the rear direction. Utilized in a stand alone format, RAY SUB Technology, allows the same cabinet to be configured for any polar pattern, omni-directional as a standard direct radiating subwoofer when speakers are facing the audience, or highly directional when a speaker cabinet is rotated sideways or upwards. With arrays, RAY SUB subwoofers can be set back to back, front to front, alternate, in vertical columns, and when column length is sufficient be beam-steered upwards or downwards. Comprised of a 15 inch 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 presents an unchallenged versatility for installations and touring requirements. Digital processing for the RS15 is provided either by NEXO’s NX242 or NXAMP Powered TDcontrollers. The processing permits the RS15 to display precise directional pattern controls through DSP processed correlations of acoustic distances between transducer and vent sources.
