Electro-Voice serie MTS: point source speakers for large spaces

Designed for installation in stadiums and sports venues, MTS series Electro-Voice It consists of sixteen models, each equipped with four 15" cone speakers″.

Sixteen models make up the new serie MTS of high-performance, full-range point source loudspeakers Electro-Voice, each equipped with four 15" woofers″ y dual coaxial compression drivers, medium/high frequency, to generate more than 151 peak dB sound pressure.

The four low frequency drivers, slot loaded, are symmetrically coupled to the same full-range waveguide as the compression ones to create a single point source, with substantial bass response, intended to eliminate the need for additional subwoofers in many applications.

This series includes sixteen models that are based on two standard three-way configurations (MTS-4153), with coverage of 60×40 degrees or 40 x 30 degrees, as well as two cardioid configurations (MTS-6154) providing the same coverage patterns with improved low frequency directional control.

60's models×40 grades offer a peak SPL of 151 dB (music) and a peak of 154 dB (word-voice) until 55 Hz a -10 dB; while those of 40×30 grades are capable of reaching a maximum SPL of 152 dB (music) and a maximum SPL of 155 dB (word) until 50 Hz a -10 dB.

Design and technology

Each version is available with a white or black finish, and in a partially air-conditioned version (PW) for protected use or in a fully air-conditioned (FW) for full exposure to the elements. All systems have a IP55 rating, impervious to dust and water entry.

The speakers were designed using high-performance computing clusters (HPC), running proprietary modeling software, designed by electric vehicle engineers.

The engineering team repeated hundreds of FEA simulations to achieve optimized system performance, the result of which were new technologies, as lossless dual waveform converter Hydra, driving a constant directivity waveguide with a coherent arc source, which according to the company helps guarantee employer control below 350 Hz.

The MTS series is designed for use with amplification and processing of Dynacord, as part of a hardware and software ecosystem powered by Sonicue, contributing to a more energy efficient system design, with performance optimization and system protection features.

Patented speaker settings and limiter functions are intended to ensure optimal performance, with long-term reliability at very high output levels, as explained by Electro Voice.

Besides, The company provides a package of design files for advanced simulation of acoustic and mechanical systems. The software EV Preview Loudspeaker deElectro-Voice facilitates faster, more accurate creation of acoustic designs with MTS, including those that complement the series, like the dual 18 subwoofer″ recommended X12i-128 dual.
