Monitor Audio PLIC II ceiling speakers feature an 8-inch long throw bass driver with Rigid Diaphragm Technology (RDT II) cone technology to provide immensely powerful bass lines. This is achieved by the RDT cone reacting to an audio signal with lightning fast precision without deformation. A rigid aluminium baffle houses dual C-CAM mid-range drivers and an Micro Pleated Diaphragm (MPD) high frequency transducer, directed towards the listening area to deliver the best possible sound balance to the listener.

All PLIC II drivers employ a heavy duty motor system integrating an under-hung motor assembly to ensure the coil always remains in the gap, even when driven hard. The addition of copper ‘shorting’ rings greatly improves magnetic linearity and lowers intermodulation distortion, resulting in crisp and clear audio delivery. A world first for an in-ceiling speaker!

Designed for installation in both new build and retrofit projects, the PLIC II in-ceiling speaker features Monitor Audio’s unique Tri-Grip fixing system. This 3-position ‘dog leg’ style fixing provides a greater contact surface area than other types. This system, combined with the magnetic grille, saves the installer both time and money by speeding up the speaker fitting process.

Monitor Audio has designed the PLIC-BOX II, an optional pre-construction MDF back box for the PLIC II.

To satisfy the interior designer and end user, the circular grille can appear almost invisible, by being painted to match the room décor. Monitor Audio also offers a square option to match lighting fixtures and ventilation.
