CI 45

PMC Ci45 in-wall speaker — H 450mm format. The PMC Ci 45 is a two-way in-wall loudspeaker in a rectangular 300×450mm format, housing a 6.5-inch natural fibre woofer and 27mm soft-dome tweeter with a 1.65m ATL transmission line. The taller format and larger woofer compared to the Ci 30 provides greater bass output and a lower frequency response of 45Hz, suited to medium-sized rooms.

Technical background

The Ci45 extends the ATL to 1.65 metres compared to the Ci30's 1.5 metres, delivering enhanced bass extension to 45 Hz from an in-wall cabinet. The same 5.25" Natural Fibre driver and 27mm tweeter provide the tonal continuity expected of the PMC Ci range.

Design story

Designed as the medium-format option in the Ci range, the Ci45 suits rooms where the Ci30 would be acoustically marginal but the Ci65 is too large. The ATL ensures consistent bass performance regardless of wall construction.
