Product Description

In-Ceiling Speakers
Hear No Evil, See No Evil

Want great surround or multi-room sound but have nowhere to put box-type speakers? Maybe the Aesthetics are a real issue or even placement. Never fear, good quality In-Ceiling speakers could be just the answer. They’re usually round and have white grilles that can painted so in most rooms they are almost invisible. Angled drivers are also available to direct the sound appropriately.

The Niles Audio CM4PR Ceiling Mount speaker is designed for rooms with limited space. The rear wave control enclosure keeps sound from transferring to adjacent rooms. It comes with a magnetically-attached paintable metal grille and is supplied as a single speaker.


The CM4PR looks a bit different than your average in-ceiling speaker and with good reason. The chamber at the back of the speaker helps to reproduce a wider frequency range while also limiting the amount of sound that leaks into adjacent spaces. That makes this speaker an excellent choice for small rooms and spaces where you otherwise might not be able to install an in-ceiling speaker. But even if you're not limited by space, the CM4PR is a great performer.

The CM4PR's rigid polymer cone delivers clarity and bass response that will surprise you from a speaker this size. It has a rigid 85mm mineral-filled polypropylene cone woofer with a butyl rubber surround to damp resonance and long life. The 25mm fluid-cooled Teteron dome tweeter provides smooth highs and a wide dispersion pattern. The speaker is mounted into a custom Rear Wave Enclosure to enhance bass response, and to keep sound in the intended area. Included is a 135mm diameter MicroThin grille, which attaches magnetically to the speaker. The 6mm thick grille is easy to install, and blends with the room's aesthetics. It is rust-resistant, and paintable to match any décor. An optional SG4C square grille is also available, if desired.

Moisture Resistant

The enclosure, speaker, and grille are weather-resistant, so you can install the speaker in moist environments, including bathrooms and outdoors under eaves. Each CM4PR is equipped with spring-loaded post terminals on the end of the enclosure. The terminals can accept up to 12-gauge speaker wire but we would suggest 14-gauge is sufficient for most normal applications. Short wire runs of less than 10 metres could use 16-gauge wire and 12-gauge wire for runs of between 25 metres and 30 metres. We don't recommend running wire longer than this and there are better alternatives

Note: When running speaker wire inside walls or ceilings, special jacketed cable (CL-2 or CL-3) should be used to protect the wire and for fire prevention. If unsure, you should consult your local building inspectors about code compliance requirements.
