7.2.2 GEO T2815 Dimensions
7.2.3 Architects’ & Engineers’ Specifications
The 2-way full range tangent array module shall have two 8 inch 16 Ohm long excursion neodymium hi-
flux cone transducers in series, two rear passive acoustic resistors and a 1.4 inch exit 16 Ohm
neodymium compression driver on a hyperboloid reflective wavesource. Coverage shall be
configuration-dependent in the vertical plane and 120° in the horizontal plane. The system shall have a
nominal sensitivity of 107dB (105dB wideband). When driven by a NEXO NX242 Digital TDcontroller
properly connected to amplification capable of delivering 5200 Watts into a 5 Ohm load (6 cabinets per
channel in parallel), the system shall produce 135dB peak SPL (for a single enclosure: configuration-
dependent when arrayed) with a frequency response of 85 Hz to 19 kHz ±3 dB (77 Hz to 20 kHz ±6 dB).
The system shall have an active crossover with DSP algorithms and a crossover point of 1.3 kHz.
Electrical connections shall be made via one 6 pole AMPHENOL EP6 socket and one 6 pole
AMPHENOL EP6 plug. The system shall have a 15° trapezoidal enclosure constructed of 18 ply Baltic
birch (midsection) and aluminium, finished in structured black coating and having exterior dimensions
no greater than 249mm H x 903mm W x 537mm D (9 13/16 in H x 35 1/2 in W x 21 1/8 in D): the
system shall weigh 29kg (63.9 lbs). Exterior hardware shall include an integral array assembly system
with logarithmic steps and 0.01° precision: interior components shall be protected by an injection-
molded polyurethane Configurable Directivity Device flange. The full range system shall be the NEXO
GEO T2815 with a NEXO NX242 Digital TDcontroller. Other integrated loudspeaker/controller systems
shall be acceptable, provided submitted results of testing by an independent laboratory verify that the
above specifications are equalled or exceeded.
