The Electro-Voice MTS-4153-43PWB is a full-range, high-output, point-source loudspeaker system with exact directivity for very-long-throw applications. MTS is the product of a holistic loudspeaker design approach. 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 slotloaded, 15-inch high efficiency low-frequency drivers are symmetrically coupled to the same full-range constant directivity waveguide as two coaxial mid/high frequency compression drivers. This creates a true point-source with substantial bass response, discarding additional subwoofers in many applications. The three-way MTS-4153-43PWW has a 40° x 30° coverage pattern.
The loudspeaker can deliver 152 dB peak (music) and 155 dB peak (speech) and low-frequency response extends to 50 Hz at -10 dB. The speaker is typically configured in biamp mode with two low-frequency inputs driven as a single 4 Ω load. The installer could also choose to drive the lowfrequency inputs separately using two cable runs to minimize signal losses over long distances.
The loudspeaker is designed for indoor or for outdoor use under an overhang or roof.
All MTS loudspeakers have an IP55 rating, indicating that they are impervious to dust and water ingress. MTS is engineered for use with Dynacord IPX series amplifiers. Proprietary speaker settings and limiter functions ensure exceptional performance with longterm 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.
