Electro-Voice MTL-1X User manual

Technical Specifications:
TheElectro-Voice®MTL-1X is a 1,200-watt subwoofer
loudspeaker system which combines the attributes of
bothhorn-loadedandventedbox designs.TheMTL-1X
designutilizesthe unique double SubScoop™ cabinet
constructionwith two EVX-180B woofers,asused in X-
ArrayTM concert systems. The design behaves like a
hornover much of its range, but withoutthe time delay
and weight problems usually associated with
conventionaldesigns.Vented-box principles takeover
for the lowest octave and assist in producing
exceptionally high levels of clean, punchy bass from a
modest-sizedbox. The reverse woofer orientation has
been used to optimize the rear chamber volume and
decrease the horn flare rate for extended low end
performance. When used with the MTH-1 mid/high
module, the MTL-1X provides high-output sound
reinforcement for clubs, large halls, or outdoor events
ina compact package which can be moved easily by a
two-person crew.Although the MTL-1X was designed
for use with the MTH-1 system, it may be used to
augment the bass performance of any Electro-Voice
stage system.
