The Bogen HFCS1 and HFCS1LP ceiling loudspeakers deliver superior sound and clear intelligibility in a variety of ceiling environments. The system can be easily installed in hard-surfaced ceilings, suspended ceilings, and new constructions. Both speakers offer several levels of power output controlled via a front-mounted rotary tap selector switch (under grille). The low-distortion speaker design, coupled with a computer-matched venting system, delivers high intelligibility and exceptional low-frequency response for both music and speech reinforcement.
