Applications
The SM12CXT is optimized for high ceiling applications such as arenas,
convention centers, gymnasiums, and auditoriums. The extreme high
efficiency and higher "Q" of the 12CX with its powerful 12" speaker and
1" exit compression driver, provides the increased available SPL often
required in these high ceiling applications. In 70.7V/100V systems this
high efficiency can also result in lower tap settings.
General Description
SM Series loudspeakers offer quality sound reproduction and
contemporary styling. The SM12CXT features the 12CXT60—a 250W
loudspeaker that combines a 12" diameter, low frequency transducer and
a 1" exit compression driver. The speaker has a curvilinear, treated-paper
cone for lower harmonic distortion, and a built-in crossover network
for proper frequency transition between the two reproducers. The low
frequency transducer and the high frequency driver feature permanently
aligned voice coils for low distortion performance. The copper coils have
Polyimide voice coil formers.
The SM12CXT features a wood enclosure with a metal grille. Internal
hardware, for flying, includes multiple (12)
1
⁄4"-20 inserts for overheard
suspension in almost any orientation.
A 90˚ conical pattern (2kHz octave band) and amazing efficiency make
the SM12CXT a perfect choice for a wide variety of applications
including school auditoriums, gymnasiums, cafeterias, church sanctuary
systems, and more.
This perforated top panel is designed for use on the Atlas Sound FMA
and 700 series floor mount vertical equipment racks.
