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.

W8LM specifications

The Martin Audio W8LM is a compact line array system that has garnered significant attention in the professional audio industry, celebrated for its versatility, high performance, and exceptional sound quality. Designed primarily for both touring and installation applications, the W8LM offers a powerful solution for venues of all sizes, from small clubs to large theaters and festivals.

One of the standout features of the W8LM is its lightweight and compact design, which makes it easy to transport and rig. Weighing in at just over 30 kg (66 lbs) per cabinet, it allows for efficient deployment without sacrificing audio performance. This portability is complemented by Martin Audio’s innovative rigging system, which ensures fast and secure setup in various configurations, meeting different venue requirements.

In terms of technology, the W8LM incorporates advanced acoustic design features that include a dual 6.5-inch neodymium low-frequency driver and a 1-inch high-frequency driver. This combination results in a well-balanced frequency response that can deliver crystal-clear highs and powerful lows. The system also boasts a wide horizontal dispersion of 100 degrees, enabling it to cover expansive audiences without dead spots, while its 8-degree vertical dispersion allows for precise control over the sound field.

Another critical characteristic of the W8LM is its ability to function seamlessly in conjunction with other Martin Audio products, particularly the W8LC low-frequency extension. This flexibility allows sound engineers to tailor the system to suit diverse performance requirements, ensuring optimal audio delivery across any event or venue.

The W8LM also integrates Martin Audio’s proprietary Wavefront Sculpture Technology (WST), which enhances the coherence of sound waves and minimizes interference between cabinets. This technology enables precise phase alignment and improves intelligibility, making it particularly useful for spoken word performances and live music.

Furthermore, the W8LM is designed for durability and reliability, featuring a robust cabinet construction that withstands the rigors of touring, while its weather-resistant options make it suitable for outdoor events.

In conclusion, the Martin Audio W8LM line array system is a highly versatile solution that combines advanced technologies with exceptional sound quality. Its commitment to portability, sound clarity, and adaptability makes it an ideal choice for audio professionals seeking a compact yet powerful audio solution. Whether used in a live concert setting or an installation, the W8LM stands out as a premier choice for delivering outstanding audio experiences.
