CI140

PMC Ci140 on-wall speaker — 1400mm tall format. The PMC Ci140 is an on-wall or in-wall loudspeaker in a tall 300×1400mm format, housing multiple natural fibre drivers and a 2.3m ATL transmission line for bass extension to 32Hz. Its 93dB sensitivity and high power handling make it suitable for large rooms or commercial installations. The tall format integrates discreetly against walls in both residential and commercial environments.

Technical background

The Ci140 uses four 5.25" Natural Fibre LTx bass drivers loaded by a 2.3-metre ATL — the longest transmission line available in an in-wall format — delivering 32 Hz bass extension from within the wall. The three-way crossover adds a dedicated 2-inch soft-dome midrange for improved vocal and instrument clarity. Sensitivity of 93 dB allows the Ci140 to achieve high SPLs with modest amplifier power.

Design story

Designed for the most demanding residential and commercial in-wall audio applications, the Ci140 brings professional-grade PMC transmission line technology to a large-format in-wall enclosure. Its quad-driver bass loading is technically unique in the industry.
