Due to Martin Audio’s policy of continuing improvement, we reserve the right to alter these specifications without prior notice. Martin Audio is committed to refining state of the art sound reinforcement, combining in-depth product and field applications research with advanced manufacturing techniques. Every Martin Audio product is built to the highest manufacturing standards and rigorously tested to ensure that it meets the performance criteria specified in the design.

The loudspeaker system shall be of the three-way switchable bi-amp/tri-amp type consisting of one 15" (380mm) direct radiating reflex loaded low frequency transducer, one 6.5" (165mm) cone driver mounted on a constant directivity horn flare with integral toroidal waveguide and one 1" (25mm) exit HF compression driver mounted on a constant directivity horn in a trapezoidal plywood enclosure. The enclosure shall be fitted with an integral pole mounting socket and threaded inserts to facilitate a variety of mounting options. Tri-amp or bi-amp operation shall be selected by a switch at the rear of the enclosure. In tri-amp mode the loudspeaker shall be operated with a separate electronic controller providing a 650Hz crossover between low and mid frequency sections and a 4kHz crossover between mid and high frequencies. In bi-amp mode the mid and high frequency sections shall be integrated by an internal 3.3kHz passive crossover network.

Performance of the loudspeaker system with its electronic controller shall meet or exceed the following criteria:

Frequency response measured 1 metre on axis shall be 55Hz-18kHz ±3dB.

High frequency dispersion at -6dB points shall be 65˚H x 40˚V.

Power handling shall be 500W AES, 2000W peak LF, 150W AES, 600W peak MF/(MF+HF), 60W AES, 240 peak HF.

Rated impedance shall be 8 ohms LF, 16 ohms MF/(MF+HF), 16 ohms HF.

Maximum SPL measured at 1 metre on axis shall be 127dB continuous, 133dB peak.

Dimensions (W) 435mm x (H) 708mm x (D) 425mm (17.1ins x 27.9ins x 16.7ins).

Weight 32kg (70.5lbs).

The loudspeaker system shall be the Martin Audio WT3.
