Electro-Voice launches MTS series point-source loudspeakers for large venues

Electro-Voice is expanding its portfolio of sound solutions for stadiums and sports venues with the 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 reportedly capable of generating more than 151 dB peak SPL with exact directivity for very-long-throw applications.

Four slot-loaded, low-frequency drivers are symmetrically coupled to the same full-range waveguide as the compression drivers to create a 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 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 for dust and water ingress.

"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", says the company.

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 used 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, according to the brand.

MTS is engineered for use with amplification and processing from Dynacord as part of a SONICUE-driven hardware/software ecosystem. A package of design files is provided for acoustical and mechanical system simulation in venues. Electro-Voice PREVIEW Loudspeaker Software can be used with MTS, including those that augment the full-range MTS models with the recommended X12i-128 dual-18” subwoofer.

Typically, an MTS installation will involve fewer cable runs, lower installed weight, less complex rigging, and fewer amplifier channels for equivalent performance. This positions MTS as a go-to solution, providing the highest possible value to the customer.
