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.

WT3 specifications

The Martin Audio WT3 is a versatile and high-performance loudspeaker designed primarily for portable sound applications, including live events, corporate functions, and installations. Renowned for its exceptional sound quality and robust build, the WT3 is a solid choice for audio professionals seeking reliable performance in various environments.

At the core of the WT3 is its advanced driver technology. The loudspeaker features a custom-designed 12-inch LF (low frequency) driver and a 1-inch HF (high frequency) compression driver, ensuring a well-balanced frequency response and high output capabilities. This combination allows the WT3 to deliver deep, punchy bass while maintaining clarity and detail in the mid and high ranges. With a frequency response that spans from 60 Hz to 20 kHz, the WT3 is capable of reproducing a wide spectrum of audio content with fidelity.

One of the standout features of the WT3 is its unified design. The cabinet is constructed from high-quality birch plywood, which not only enhances durability but also contributes to superior acoustic performance. The enclosure is carefully engineered to minimize resonance and distortion, resulting in cleaner sound reproduction. Moreover, the WT3's design includes multiple rigging points, allowing for easy suspension or stacking, making it adaptable for different setups and venues.

In terms of connectivity, the WT3 is equipped with standard SpeakON connectors, facilitating easy integration with various amplification systems. The speaker is also designed for bi-amp operation, allowing users to drive the LF and HF sections separately for optimal performance. This feature is particularly beneficial for larger sound systems requiring precise control over each frequency range.

The WT3 is designed with user convenience in mind. Its lightweight construction simplifies transportation, while the built-in handles make it easy to carry and set up. Additionally, the speaker is available in a variety of finishes, including weatherproof options, making it suitable for both indoor and outdoor applications.

Overall, the Martin Audio WT3 stands out for its powerful performance, durable build quality, and adaptability. With its exceptional audio characteristics and user-friendly design, it continues to be a favored choice among sound professionals and event organizers looking for a reliable and effective loudspeaker solution.
