Architecture & Engineering Specications
The in-wall speaker shall consist of a 100 mm (4.00") full range, point source Dual Concentric™ transducer mounted in an injection moulded front
bae manufactured from UV/weather resistant UL94V-0 ABS material. The two-way system shall incorporate an optimised low loss crossover
network. The wiring terminals shall be screw terminal connectors.
Performance of the in-wall speaker shall meet or exceed the following criteria: The system shall have a conical coverage angle of 130 degrees
(1 kHz to 6 kHz). Frequency response measured on axis shall be 73 Hz -54 kHz (-10 dB from rated sensitivity, measured in an IEC bae in an
anechoic chamber) with no equalization. Sensitivity shall be 88 dB (1 W @ 1 m). Long-term power handling capacity as dened in EIA-426B test
shall be 60 W, recommended amplier power 120 W @ 8 Ohms. The nominal system impedance shall be 8 Ohms.
A weather resistant perforated steel grille covers the transducer. Both the grille and bae shall be paintable. The system shall not exceed the
following dimensions: 238 x 159 x 91 mm or 9.4 x 6.3 x 3.6" (H x W x D) Hole cutout size shall be 206 x 135 mm (8.11 x 5.3").
The Tannoy in-wall speaker system shall be the.....iw4 DC-WH.
