Name: C6.8T
Rating: 4.7 (23 reviews)

Featuring a 6.5" (165mm) bass driver and a 0.8" (19mm) dome tweeter, The C6.8T is ideal for flush mounted applications where full frequency performance and wide dispersion are required from a compact, ported enclosure.

Features

Two-way high performance flush mounting ceiling speaker
6.5" (165mm) UL94V-0 carbon fibre loaded polypropylene cone bass driver
Very wide dispersion – 150° conical up to 7kHz
High & low impedance operation – transformer included
106dB continuous max SPL @ 1 metre
75W power handling – 16 ohm (40W transformer)
Polyswitch and thermal fuse protection
Steel backcan
UL2043 & UL1480

Applications

Fixed installations in ceiling and walls
Low ceiling environments

The side-by-side arrangement of the drive units maintains smooth response up to 75° off-axis and makes the C6.8T perfectly suited for use in low ceilings, where its broad coverage means that fewer units will be required to deliver premium sound over the required listening area. The C6.8T features a 4-point mounting system for ease of installation and a rising clamp plug and socket permit easy pre-wiring with up to 2.5mm2 conductors.

These products comply with UL2043 Fire Tests for Heat & Visible Smoke Release for Discrete Products and their Accessories Installed in Air Handling Spaces.

Architectural Specs

Martin Audio C6.8T

The loudspeaker shall be a two-way, in-ceiling system consisting of a 6.5” low frequency transducer and a 0.8” dome high frequency transducer mounted in a ported enclosure. The enclosure shall comprise a pressed steel backcan with a UL94V-0 fire-rated moulded baffle. The transducers shall be protected by a removable, perforated steel grille.

Input connection shall be made via a four-pin rising-clamp plug and socket with loop-through capability to enable pre-wiring with up to 2.5mm2 cable prior to installation. The connector shall be protected from fire by a steel cover with a clamped cable entry. An attachment tag on the backcan shall enable direct attachment to the building structure as a secondary support.

The loudspeaker shall include a steel support ring and tile rails.

Dispersion shall be 150° conical up to 7kHz. The on-axis frequency response shall be 90Hz-20kHz +/- 3dB and the loudspeaker shall produce a maximum SPL of 112dB peak calculated at 1 metre. Power handling shall be 75W AES, 300W peak.

The loudspeaker shall be equipped with a transformer for 70V or 100V line operation, with taps selected by a rotary switch on the front baffle. The switch shall also provide for 16 ohm low impedance operation of the loudspeaker.

Dimensions (OD x D) shall be 260mm x 181mm (10.2ins x 7.1ins). Weight shall be 3.5kg (7.7lbs).

The loudspeaker shall be the Martin Audio C6.8T.
