MTS High Output Point Source
2
System overview
MTS loudspeakers are very high output, long-throw, horn-loaded, point-source systems
designed for high performance permanent install applications, such as sports arenas, houses
of worship, and performing arts centers. The series represents the culmination of EV's
extensive experience in designing rugged, large format horn-loaded systems that can survive in
harsh, direct exposure environments.
All models feature stainless steel hardware and grilles, weatherized transducers, and durable
birch plywood enclosures with internal bracing and a highly durable polyurea coating. The dual
8-conductor terminal blocks, with a current capacity that exceeds 40 amps (continuous), are
mounted in a cast aluminum input cup. Gland nut plates are included with each speaker to
seal the input panel and to present a clean, consistent look for the rear of the loudspeaker.
The fully weatherized models are specifically designed for harsh environments, including
direct exposure to the elements. In addition to the features already described, all interior and
exterior surfaces of the fully weatherized enclosures are finished with a weather resistant
coating that seals the marine-grade plywood. The grilles are backed with a special
hydrophobic cloth that minimizes water intrusion without impeding the acoustic output of the
speaker.
MTS loudspeakers integrate seamlessly with Dynacord IPX series amplifiers and SONICUE
sound system control software. For ease of set up and installation, the SONICUE software has
presets for all MTS products.
MTS-4153 Standard Models
Each MTS-4153 standard horn-loaded loudspeaker consists of four 15-inch (381 mm) LF
drivers and two 1.4-inch (36 mm) exit coaxial mid/high compression drivers. The transducers
couple to a large, constant directivity, co-entrant arc source horn. Two coverage patterns are
available: 40° x 30°, and 60° x 40°. The compression drivers mount at the throat of the horn to
maximize efficiency and eliminate acoustic obstructions within the horn that can interfere with
consistent coverage. The large horns provide accurate pattern control down to 400 Hz. The
coaxial mid/high compression drivers feature a high power passive crossover with 24 dB per
octave slopes to minimize the required number of amplifier channels. The enclosure is
trapezoidal in both the horizontal and vertical planes, in such a way that tight packing the
loudspeakers in a cluster results in the smoothest coverage transition. MTS loudspeakers are
available in either white or black. Each loudspeaker has 24 M10 hard points for suspension in
either horizontal or vertical configurations. Suspend the speakers from individual cable
systems or use third-party structural frames.
MTS-6154 Cardioid Models
MTS-6154 models deliver complementary performance to that of the standard three-way
models and are almost identical to them except for the addition of two 15-inch woofers
positioned in a separate chamber at the rear of the cabinet. This extra pair of woofers is
arranged in a cardioid configuration that substantially reduces acoustic energy behind the
loudspeaker and extends pattern control to the low frequency cut-off of the system. The
cardioid section requires its own processed amplifier channel. Cardiod models have 32 M10
suspension points.
