The 'Go to' In Ceiling Speaker

The latest product to join the Platinum II range, the PLIC II in-ceiling speaker, meets the demands put on speaker manufacturers by providing a winning combination of high quality sound, ease of installation and a discreet design.

Key Features

  • Compact dimensions
  • 4 drivers – full three-way design
  • 8” Long throw Bass driver featuring RDT II cone technology
  • Dual 2” C-CAM mid-range drivers for wider dispersion
  • MPD high frequency transducer
  • Angled mid-range and high frequency drivers – directed towards listening area to provide uniform mid and high frequency dispersion


The Monitor Audio PLIC II In-Ceiling Speaker is designed with an MDF back box with pre-determined air volume of 24L. The rigid box is available with pre-loaded internal damping material to provide the best possible sound absorption and reduce standing waves. The circular grille can appear almost invisible by being paintable in order to ensure a seamless blend into your living environment. An optional square grille can be used with this model.


The Monitor Audio PLIC II In-Ceiling Speaker features an 8” long throw bass driver with Rigid Diaphragm Technology (RDT-II) to provide immensely powerful bass lines. This is achieved by the RDT cone reacting to an audio signal with lightning fast precision without deformation. To provide the listener with a uniform frequency spectrum when the speaker is played at higher frequencies, additional dual mid-range drivers, featuring C-CAM cone technology and Monitor Audio’s Micro Pleated Diaphragm (MPD) transducer are mounted on a rigid aluminium baffle and directed towards the listening zone to provide uniform mid and high frequency dispersion. All PLIC II drivers employ a heavy duty motor system which deploys an under-hung motor assembly to ensure the coil always remains in the gap, even when driven hard. The additional copper ‘shorting’ rings greatly improve 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. The 3-way 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.
