The MTS-6154-64CPWB 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-6154-43CPWB is augmented by a cardioid low-frequency chamber at the rear of the cabinet, resulting in full-range directivity with reduced spill outside the intended pattern, improved intelligibility, and increased low-frequency output. The speaker's coverage pattern is 60° x 40°.

The loudspeaker can deliver 151 dB peak (music, with low-frequency response that extends to 55 Hz at -10 dB) and 154 dB peak (speech).

The speaker is typically configured in triamp mode with the two front low-frequency inputs driven as a single 4 ohm load. The installer could also drive the front low-frequency 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 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.
