L-Acoustics X15 HIQ 2-Way Coaxial Speaker w/ Active Crossover

The X15 HiQ is a coaxial system designed as a reference stage monitor. The enclosure features a 3’’ diaphragm compression driver coaxially-loaded by a 15’’ low frequency transducer in a bass-reflex cabinet. The L-Vents laminar vented ports reduce turbulence and port noise at high levels to increase LF efficiency. The X15 HiQ operates from 55 Hz to 20 kHz. The coaxial transducer arrangement and its ellipsoid waveguide produce a 40° x 60° directivity pattern with a smooth tonal response free of secondary lobes over the entire frequency range. As a result, X15 HiQ boasts an exceptional immunity to feedback. The L-Acoustics amplified controllers ensure the advanced crossover functions, time alignment, linearization, and L-Drive protection of the transducers.

This is a passive speaker – requires 2 channels of amplification for each speaker box.
