5 115XT HIQ COAXIAL STAGE MONITOR
a
L-ACOUSTICS ® 115XT HiQ features 3'' diaphragm compression driver loaded onto a constant directivity conical
waveguide united in a coaxial configuration with a 15'' low frequency transducer, integrated into a compact low profile
bass-reflex tuned enclosure.
Managed by the LA4 amplified controller, the two-way active filtering encompasses advanced crossover functions,
system EQ, HF and LF transducer time-alignment, and protection of the transducers. The linearization and protection
of the transducers is defined by the drive parameters contained in the LA4 amplified controller. The nominal impedance
of the 115XT HiQ enclosure is 8 ohms.
The coaxial transducer and conical waveguide arrangement produces a 50° axi-symmetric directivity output along with a
smooth tonal response free of secondary lobes over the entire frequency range, and provides immunity to feedback.
