Electro-Voice MTS-4153-43FWB (Black)

The MTS-4153-43FWB is a full-range, high-output, pointsourceloudspeaker with exact directivity for very-longthrowapplications.MTS is the product of a holistic system approach.

Acoustic design, amplifier matching, and digitalprocessing are optimized with proprietary software toensure precisely distributed SPL that is balanced andcontrolled throughout the entire coverage area, even atfull output. Four slot-loaded, 15-inch high efficiencylow-frequency drivers are coupled to the same fullrangeconstant directivity waveguide as two coaxialmid/high frequency compression drivers.

This creates atrue point-source with substantial bass response,eliminating the need for subwoofers in manyapplications.The three-way MTS-4153-43FWB has a 40° x 30°coverage pattern.The loudspeaker can deliver 152 dB peak (music, withlow-frequency response that extends to 50 Hz at-10 dB) and 155 dB peak (speech).The speaker is typically configured in biamp mode withtwo low-frequency inputs driven as a single 4 Ω load.The installer could also drive the low-frequency inputsseparately using two cable runs to minimize signallosses over long distances.The loudspeaker is designed for outdoor use with fullexposure to the elements.All MTS loudspeakers have an IP55 rating, indicatingthat they are impervious to dust and water ingress.MTS is engineered for use with Dynacord IPX seriesamplifiers.

Proprietary speaker settings and limiterfunctions ensure exceptional performance with longtermreliability at extremely high output levels. Apackage of design files is provided for advanced systemsimulation in venues. Electro-Voice PREVIEWLoudspeaker Software is the fastest and most accurateway to create acoustic designs with MTS.
