The MTS-4153-43FWB is a full-range, high-output, point-source loudspeaker with exact directivity for very-long-throw applications.

MTS is the product of a holistic system approach. Acoustic design, amplifier matching, and digital processing are optimized with proprietary software to ensure precisely distributed SPL that is balanced and controlled throughout the entire coverage area, even at full output. Four slot-loaded, 15-inch high efficiency low-frequency drivers are 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, eliminating the need for subwoofers in many applications.

The three-way MTS-4153-43FWB has a 40° x 30° coverage pattern.

The loudspeaker can deliver 152 dB peak (music, with low-frequency response that extends to 50 Hz at -10 dB) and 155 dB peak (speech).

The speaker is typically configured in biamp mode with two low-frequency inputs driven as a single 4 Q load. The installer could also drive the low-frequency inputs separately using two cable runs to minimize signal losses over long distances.

The loudspeaker is designed for outdoor use with full exposure to the elements.

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 long-term reliability at extremely high output levels. A package of design files is provided for advanced system simulation in venues. Electro-Voice PREVIEW Loudspeaker Software is the fastest and most accurate way to create acoustic designs with MTS.
