6.5" Coaxial Ceiling Speaker

The Bogen HFCS1LP is a high-fidelity ceiling speaker built for distributed audio systems. It uses a 6.5" polypropylene cone woofer and a 0.75" polycarbonate dome tweeter in a coaxial layout. The speaker handles 75 watts at 16 ohms or 32 watts on 70V and 100V lines. Sensitivity is rated at 89 dB SPL averaged from 100 Hz to 10 kHz.

Front-Mounted Tap Selector and Plug-In Wiring

A front-mounted rotary switch lets installers choose power taps of 32, 16, 8, 4, 2, and 1 watt for 70V systems or 32, 16, 8, 4, and 2 watts for 100V systems without removing the grille. The 16-ohm bypass setting supports direct low-impedance amplifier connections. A plug-in connector with loop-through terminals speeds up daisy-chain wiring. Integral swing-out clamps secure the speaker in ceilings up to the mounting depth allowed by the low-profile housing.

Foreground Music and Paging in Commercial Spaces

This speaker suits offices, retail areas, and hospitality venues that need even coverage from a single overhead point. The wide-dispersion coaxial driver and computer-matched venting deliver consistent off-axis response and full bass output. It is not intended for buyers who need a sealed-back enclosure for fire-rated ceilings, nor for installers who require a smaller cutout diameter than the 12.31" frame provides. Home theatre enthusiasts seeking a dedicated LFE channel or surround-format decoding should look at purpose-built home cinema speakers.

Questions about this item

Will the polypropylene cone or polycarbonate dome need replacement after years of use?

The 6.5" polypropylene cone and 0.75" polycarbonate dome use compounded rubber surrounds built for lasting performance, so no routine driver replacement is expected.

What limits output first during long listening sessions at high volume?

The 75 W power rating at 16 ohms is the thermal ceiling; sustained levels above that will trigger protection before any mechanical limit is reached.

How much heat does the speaker produce when running all day at moderate levels?

At typical foreground levels the 89 dB sensitivity keeps amplifier current modest, so the steel back-can stays only warm to the touch with no active cooling required.
