Electro-Voice has expanded its portfolio of sound solutions for stadia and sports venues with the MTS series of full-range, high-output, long-throw, point-source loudspeaker systems. Each MTS model is equipped with four 15-inch woofers and dual coaxial mid/high frequency compression drivers. The system is capable of generating more than 151dB peak SPL with high directivity for very-long-throw applications.
The MTS loudspeaker geometry, amplifier matching and digital processing are computer-optimised for SPLs that remain 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 point-source with substantial bass response, eliminating the need for additional subwoofers in many applications.
The MTS series comprises 16 models. 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 LF directional control.
The 60° x 40° models can deliver extremely high SPLs: 151dB peak (music) and 154dB peak (speech) down to 55Hz at -10dB; the 40° x 30° models are capable of 152dB peak (music) and 155dB peak (speech) down to 50Hz at -10dB. 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 modelling software designed by EV engineers. The engineering team generated 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 350Hz.
The launch of MTS brings an evolution of EV’s pioneering manifold loudspeaker technology and MH horn technology to advanced levels of audio performance. 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, for cost-effective and energy-efficient system design with unique performance optimisation and system protection features. Proprietary settings and limiter functions ensure performance with long-term reliability at extremely high output levels.
A complete 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-inch subwoofer.
MTS design files are available now for project planning. MTS begins shipping in Q4 2021.
