CI90SLIM
Ultra-Slim In-Wall Reference — PMC ATL Accuracy in the Thinnest Profile
Description ⌄
PMC Ci90slim in-wall speaker — slim 190mm wide format. The PMC Ci90slim is a slim-profile two-way in-wall loudspeaker in a tall 190×900mm format, designed to be concealed within wall cavities where depth is restricted. It uses a 5.25-inch natural fibre woofer and 27mm soft-dome tweeter with a 1.65m ATL transmission line, and is suited to custom installation applications requiring a minimal visual footprint.
Technical background
The Ci90slim achieves a 103mm depth — shallower than most in-wall speaker back boxes — while housing a 1.65-metre PMC ATL. The Qikfire mounting system with interlocking bracket and level adjustment enables precise installation alignment without specialist tools.
Design story
Developed in Luton specifically for contemporary architecture where aesthetic demands and construction constraints limit the options for high-performance audio integration, the Ci90slim brings PMC's transmission line standards to the most demanding installation contexts.
