  • Page 4 NEXO released its first gradient subwoofer, the CD12, which has been complemented since then by CD18, GEO SUB and RS15. These have been quickly adopted worldwide as standards and are considered today as state-of-the-art subwoofers. This success is a consequence of proper cabinet design and optimized definition of phase relations through sophisticated DSP algorithms leading to high directional control and SPL output.

    For fixed installations, wind loading has to be taken into account in accordance to the national standards. The RS Rigging System requires regular inspection and testing by a competent test centre. NEXO recommend that the system is load tested and certified annually or more frequently if local regulations require.

    Low frequency level on stage is therefore significantly reduced on stage, and in the neighbouring environment in open air venues. Because of their directional pattern, Gradient subwoofer are also less sensitive to room eigen modes. Page 39 / 76 System Manual RS Series...

  • Page 40: Monophonic Design

    Therefore, main axis efficiency must be orientated outwards (through use of delays or curving the array outward as in below figure). Such arrays must be experimented playing one side only to check Page 40 / 76 System Manual RS Series...
  • Page 41 However, it is essential to keep in mind that stereo subwoofer array design always leads to strong interferences in the centre alley vicinity (a couple of steps left and right of mixing position). A successful design requires minimizing the audience area over which these interferences occur, and therefore lots of on-site experimentation. Page 41 / 76 System Manual RS Series...

  • Page 42: Ray Sub Implementation

    RS15s and RS18s arrays must be installed with bumper set horizontally and all cabinets at 0°. Design procedure should be in agreement with what has been described in the preceding section. See following section on Steered Arrays Page 42 / 76 System Manual RS Series...

  • Page 43: Directional Mode

    50cm (20”) from the RS15 and 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. (ie “RS15s LEFT” should be installed Left and “RS15s RIGHT” should be installed Right).

  • Page 51: Aligning Rs With Main System

    Aligning RS with main system The NEXO TD Controllers factory presets are optimised to provide the best possible crossover between the RS15 and RS18 and other NEXO main systems. These crossover algorithms are defined for speaker acoustic reference points being aligned.

    Angle (in radians) =3.142 x Angle (in degrees)/180 Computer – Laptop or Desktop PC running Windows 8 with the current version of NEXO NS-1 installed. It is not possible to configure a GEO tangent array properly without using NS-1. Note that, when NS-1 designs are prepared prior to arrival at the venue, it is often necessary to modify or update the design to accommodate special circumstances.
