Martin Audio C6.8T – 6" Two-Way Flush Mount Ceiling Speaker Pair

Product Overview

The Martin Audio C6.8T is a two-way, flush-mount commercial ceiling speaker designed for distributed audio and background music applications requiring full-frequency performance from a compact, ported enclosure. Priced and sold as pairs, it features a 6.5" (165mm) bass driver and delivers 150° conical dispersion up to 7kHz for broad coverage in mid-size commercial spaces. High and low impedance operation via an included transformer ensures compatibility with 70V/100V distributed audio systems. UL2043 and UL1480 listings confirm plenum-rated commercial install compliance.

Product Description

Part of Martin Audio's Ceiling Series for commercial install, the C6.8T combines a 6.5" (165mm) UL94V-0 carbon fibre loaded polypropylene cone bass driver with a 0.8" (19mm) dome tweeter mounted side-by-side in a ported enclosure. The ported design extends low-frequency response compared to sealed ceiling speakers of equivalent driver size, delivering fuller audio reproduction suited to background music reinforcement in hospitality, retail, and corporate environments. At 106dB continuous max SPL at 1 metre and 75W power handling (16Ω), the C6.8T provides adequate headroom for moderate-to-high ambient noise commercial spaces. Polyswitch and thermal fuse protection safeguard the drivers against amplifier misuse and overload conditions, reducing field replacement costs on multi-zone installs. The 150° conical dispersion pattern ensures consistent coverage up to 7kHz across standard commercial floor plates with typical 3–4 metre ceiling heights. The steel backcan supports structural integrity and plenum containment, while the included transformer enables tap selection for 70V/100V distributed audio infrastructure. Both UL2043 and UL1480 listings confirm suitability for above-ceiling plenum runs in commercial construction projects.

Key Features

Technical Specifications

Frequently Asked Questions

Are the C6.8T speakers sold individually or as pairs?

They are priced and sold as pairs. Each purchase includes two speakers.

Is the C6.8T compatible with 70V/100V distributed audio systems?

Yes. An included transformer enables high-impedance 70V/100V operation as well as direct low-impedance 16Ω connection.

Is the C6.8T UL-rated for plenum ceiling installation?

Yes. The C6.8T carries UL2043 (air handling space) and UL1480 (in-ceiling fire safety) listings for commercial plenum installs.

What is the advantage of the ported enclosure over a sealed design?

The ported enclosure extends low-frequency response, providing fuller audio reproduction for background music applications compared to sealed ceiling speakers with equivalent driver size.

What driver protection does the C6.8T include?

A Polyswitch resettable fuse and thermal fuse protect the drivers against sustained overload, reducing field replacements on large distributed systems.

What ceiling height is the C6.8T optimised for?

The 150° conical dispersion is suited to commercial spaces with standard 3–4 metre ceiling heights. For higher ceilings consider the C8.1T.
