Electro-Voice launches MTS series loudspeaker systems

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.

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 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 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 SPLs of 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 drives a large constant directivity waveguide with a coherent arc source, ensuring pattern control to below 350 Hz.

The launch of MTS brings an evolution of EV’s manifold loudspeaker technology and MH horn technology. Manifold technology describes a method for acoustically combining the output of multiple transducers. EV pioneered this approach decades ago for high-frequency compression drivers and has refined the technology for both the coaxial compression drivers and the low-frequency drivers in these speakers.

MTS is engineered for use with amplification and processing from Dynacord as part of a Sonicue-driven hardware/software ecosystem. Proprietary speaker settings and limiter functions ensure performance with long-term reliability at high output levels. A package of design files is provided for advanced acoustical and mechanical system simulation in venues. Electro-Voice Preview Loudspeaker Software is the fastest and most accurate way to create acoustic designs with MTS, including those that augment the full-range MTS models with the recommended X12i-128 dual-18” subwoofer. MTS design files are available now for project planning. MTS begins shipping in Q4 2021.
