The LC2‑PC30G6‑4 is a 4‑inch two‑way Premium-sound Ceiling Loudspeaker which provides; wide dispersion, high efficiency, high maximum output, ease‑of‑installation, and wide‑range reproduction of music and voice.
It consists of a baffle assembly, grille, back‑can enclosure, 4‑inch coax two‑way loudspeaker and internal output‑power matching transformer. The loudspeaker features a waveguide coupled titanium coated dome tweeter. The rear enclosure provides an optimum internal volume for extended low frequency performance. The loudspeaker utilizes a second order crossover network at 3.3 kHz, with a comprehensive protection circuit to protect the network, woofer, and tweeter drivers from excessive power levels. The loudspeaker can be installed optionally with the LC2‑PC60G6‑10 ceiling subwoofer to enhance the low frequency reproduction down to 45 Hz.
