The Tannoy PCI 7DC RB 7" Premium Ceiling Speaker for Installation is a dual concentric ceiling-mounted loudspeaker designed to deliver clear, balanced audio for commercial and professional environments. Its 7-inch low-frequency driver coupled with a concentric high-frequency unit provides coherent point-source reproduction, improving speech intelligibility and musical detail. The speaker's construction supports flush installation into ceilings, offering a discreet appearance while maintaining reliable acoustic performance for background music and paging systems.

Advantages

The 7-inch woofer provides sufficient low-mid output for natural voice reproduction without excessive cabinet volume. The build quality ensures long-term durability in public spaces, and the speaker integrates with common ceiling mounting methods for straightforward installation. Its neutral tonal balance suits a wide range of audio content from announcements to ambient music.

How to use

Install the speaker into a ceiling aperture matching the product's cut-out dimensions, securing the unit with its mounting clamps or fixings. Connect the speaker to an appropriate low-impedance amplifier or distributed audio system, observing polarity and recommended wiring practices. Position speakers in a grid or spaced layout to achieve uniform coverage; aim for even spacing and consider room acoustics when determining placement. Once installed, test with speech and music material to confirm clear intelligibility and adjust system EQ or amplifier output as required.

Recommendations

For optimal speech clarity and music balance, use this ceiling speaker with compatible commercial amplifiers and line-matching transformers when integrating into distributed systems. Maintain unobstructed space above the ceiling tile for acoustic performance and service access, and plan speaker spacing based on room size and intended sound pressure level to avoid hotspots or dead zones.
