PMC Debuts ci140 and ci140sub Slimline Loudspeakers

The first two models of PMC’s new custom installation loudspeakers, the ci140 and ci140sub, debuted this week. Both are designed with a shallow depth for wall mounting and all models, apart from the ci140 and ci140sub, are also designed to be used in-wall. The use of one product for both in-wall and on-wall reduces the number of models that need to be stocked and gives the installer greater flexibility with mounting options.

The speed of in-wall mounting makes the entire range very “installer-friendly.” The ci30, ci45, ci90slim and ci65 are fitted with PMC’s Qikfire spring loaded mounting system, which, with a simple twist of a screwdriver, mounts the loudspeaker securely and quickly and permits post installation micro adjustment. Removal is just as easy as installation, with a simple twist. The on-wall mounting of each model is a very simple process using the optional interlocking wall bracket, which is designed to also offer pin-point level adjustment.

The drive units are developed from PMC’s knowledge of driver design and comprise the LT woofer and the longer throw and higher power handling version, the LTx, with their 130mm (5.25”) natural fibre cones, the 50-millimeter (2″) dome midrange and a 27-millimeter (1.1″) dome tweeter. The cabinets all feature PMC’s respected Advance Transmission Line (ATL) bass loading technology and Laminair vents, plus a sophisticated, hand-built, precision crossover.

The LT & LTx long throw woofers have a doped natural fibre dished cone and inverted dust cap, reducing the unwanted high frequency reflections from the cone surface. The high-power voice coils, in a ferrite magnet, are mounted in a low-profile basket to fit in the shallow cabinets. These drivers have been designed for use with the ATL bass loading technology found in all PMC speakers. It uses the energy generated by the bass units in a much more intelligent, efficient manner than designs based on ported or sealed boxes. In ATL speakers, the highly braced cabinet is lined with custom-designed acoustic foam that absorbs all but the very lowest frequencies. These exit from a front-panel vent, extending the low-frequency response and creating the impression of a far larger speaker.

All ci series cabinets are enclosed at the rear and are supplied in a black finish, with square perforated bezel-less metal grilles in black or white.
