CI 65

PMC Ci65 in-wall speaker — H 650mm format. The PMC Ci 65 is a high-sensitivity two-way in-wall loudspeaker using a larger 8-inch natural fibre woofer and 27mm soft-dome tweeter with a 1.8m ATL transmission line. Its 87dB sensitivity and 4Ω impedance make it particularly suited for use with multi-room or distributed audio systems where amplifier power may be limited.

Technical background

The Ci65 is a 3-way in-wall loudspeaker with dual 5.25" Natural Fibre bass drivers loaded by a 1.8-metre ATL, delivering 40 Hz extension and significantly higher sensitivity (87 dB) than comparable in-wall designs. The three-way crossover separates bass, mid and treble duties for improved clarity at higher SPLs.

Design story

Developed for larger residential spaces and commercial applications where in-wall audio needs to fill the room convincingly, the Ci65 provides the acoustic performance of a quality standmount loudspeaker from within the wall.
