Electro-Voice has introduced the MTS series of full-range, high-output, point-source loudspeakers, all equipped with four 15-inch woofers and dual coaxial mid/high frequency compression drivers and stated to be capable of generating more than 151 dB peak SPL with high directivity in long-throw applications.
The four slot-loaded low-frequency drivers are symmetrically coupled to the same full-range waveguide as the compression drivers to create a singular point source with substantial bass response, intended to eliminate the need for additional subwoofers in many applications.
The series includes 16 unique models that are based on two standard three-way configurations (MTS-4153) with 60- x 40-degree or 40- x 30-degree coverage, as well as two cardioid configurations (MTS-6154) that provide the same coverage patterns with enhanced low-frequency directional control. The 60- x 40-degree models are stated to deliver 151 dB peak SPL (music) and 154 dB peak (speech) down to 55 Hz at -10 dB; the 40- x 30-degree models are stated to be capable of 152 dB peak SPL (music) and 155 dB peak SPL (speech) down to 50 Hz at -10 dB.
Each version is available with black or white finish, and in a partially weatherized (PW) version for sheltered use or in a fully weatherized (FW) version for full exposure to the elements. All have an IP55 rating, indicating that they are impervious to dust and water ingress.
The loudspeakers were designed using High-Performance Computing (HPC) clusters, running proprietary modeling software designed by EV engineers. The engineering team iterated hundreds of FEA simulations to achieve optimized system performance, and this work led to new technologies that include the dual lossless Hydra waveform converter that that drives a large constant directivity waveguide with a coherent arc source, helping to ensure pattern control to below 350 Hz.
MTS also evolves EV’s manifold loudspeaker technology and MH horn technology to a more advanced level. Manifold technology describes a method for acoustically combining the output of multiple transducers. EV pioneered the approach decades ago for high-frequency compression drivers and has refined the technology for both the coaxial compression drivers and the low-frequency drivers.
MTS is designed for use with amplification and processing from Dynacord as part of a SONICUE-driven hardware/software ecosystem for a more energy-efficient system design with performance optimization and system protection features. Proprietary loudspeaker settings and limiter functions are intended to help ensure exceptional performance with long-term reliability at very high output levels.
A package of design files is provided for advanced acoustical and mechanical system simulation in venues. EV PREVIEW Loudspeaker Software is stated to be 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, and the series is stated to begin shipping in Q4 2021.
