Electro-Voice MTS Series: Point-source loudspeaker systems for large venues
Full-range horn-loaded loudspeaker with four 15" woofers and dual coaxial mid/high frequency compression drivers generates more than 151 dB peak SPL
Proprietary, state-of-the- science, dual lossless Hydra waveform converter feeds a coherent arc source into a large constant directivity waveguide to ensure pattern control to below 350 Hz
Cardioid versions deliver full- bandwidth directivity control that reduces sound spill outside the pattern, enhancing dynamics, improving sound quality and clarifying speech intelligibility
Electro-Voice is expanding its portfolio of sound solutions for stadiums and sports venues with the global introduction of the MTS series of full-range, high-output, long-throw, point- source loudspeaker systems.
Each MTS model is equipped with four 15" woofers and dual coaxial mid/high frequency compression drivers. The system is capable of generating more than 151 dB peak SPL with exact directivity for very- long-throw applications.
MTS represents a truly holistic approach to loudspeaker design. Loudspeaker geometry, complementary amplifier matching, and digital processing are computer- optimized to ensure precisely distributed SPL that remains balanced and controlled throughout the entire coverage area – even at full output.
Four slot-loaded, high efficiency low-frequency drivers are symmetrically coupled to the same full-range waveguide as the compression drivers to create a true point-source with substantial bass response, eliminating the need for additional subwoofers in many applications.
The MTS series includes sixteen unique models. These are based on two standard three-way configurations (MTS-4153) with 60° x 40° or 40° x 30° coverage, and two cardioid configurations (MTS-6154) that provide the same coverage patterns with enhanced low- frequency directional control.
The 60° x 40° models can deliver extremely high SPLs: 151 dB peak (music) and 154 dB peak (speech) down to 55 Hz at -10 dB; the 40 x 30 models are capable of 152 dB peak (music) and 155 dB peak (speech) down to 50 Hz at -10 dB. Each version is available with black or white finish, and each is available in a partially weatherized (PW) version for sheltered use or in a fully weatherized (FW) version for full exposure to the elements. All MTS loudspeakers have an IP55 rating, indicating that they are highly impervious to dust and water ingress.
The MTS series leverages EV’s engineering resources as part of the Bosch Group. The loudspeakers were designed using exclusive High- Performance Computing (HPC) clusters, running proprietary modeling software designed by EV engineers. The engineering team iterated hundreds of FEA simulations to achieve ideal system performance. This work led to new EV technologies, including the dual lossless Hydra waveform converter that that drives a large constant directivity waveguide with a coherent arc source, ensuring pattern control to below 350 Hz.
