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 horizontally formatted line array type, switchable passive/bi-amp. The low and mid frequency sections shall consist of two 8" (200mm) cone transducers, one direct radiating and reflex loaded and one front loaded by a constant directivity mid-horn using a toroidal phase plug and reflex loaded, with both sharing the same enclosure. The drivers shall operate in tandem to produce low frequencies up to 300Hz. Above 300Hz, the direct radiator driver shall be rolled off by an internal passive network and the horn loaded driver reproduce mid frequencies up to 2.2kHz. The high frequency section shall consist of two 1" (25mm) horn elements vertically mounted to produce a low-curvature vertical wavefront. The enclosure shall be constructed of heavily braced multi-laminate plywood with all flying hardware integral and captive. Bi-amp or passive operation shall be selected by a switch at the rear of the enclosure. In bi-amp mode the loudspeaker shall be operated with a separate electronic controller providing a 2.2kHz crossover between mid and high frequencies. In passive mode the mid and high frequency sections shall be integrated by an internal 2.2kHz 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 60Hz-18kHz ±3dB.

High frequency dispersion at -6dB points shall be 100˚H x 7.5˚V.

Power handling shall be 400W AES, 1600W peak FR/(LF + MF), 75W AES, 300W peak HF.

Rated impedance shall be 12 ohms FR/(MF + HF), 12ohms HF.

Maximum SPL measured at 1 metre on axis shall be 125dB continuous, 131dB peak.

Dimensions (W) 620mm x (H) 243mm x (D) 400mm (24.4ins x 9.6ins x 15.8ins).

Weight 29kg (64lbs).

The loudspeaker system shall be the Martin Audio W8LM.
