Polk Audio RC80i Slim High-Performance In-Ceiling Speaker
The Polk Audio RC80i in-ceiling speaker is a standout solution for spaces that demand powerful sound from an exceptionally shallow installation. With a mounting depth of just 79 mm, yet featuring a full 8-inch driver, the RC80i delivers a level of bass impact rarely achieved by slim in-ceiling speakers.
Designed for rooms where wall space is limited but audio performance cannot be compromised, the RC80i offers rich, room-filling sound with wide dispersion—ensuring consistent listening quality from anywhere in the room.
Big Sound from an Ultra-Slim Profile
Despite its compact depth, the RC80i produces deep, controlled low frequencies that rival much larger in-ceiling designs. Its large driver surface area allows it to move more air, resulting in stronger bass presence without the need for bulky enclosures.
This makes it an ideal choice for living spaces, kitchens, bedrooms, and home cinema systems where clean aesthetics and high output must coexist.
True Stereo Performance from a Single Speaker
The Polk RC80i features a specialised tweeter housing that delivers clearly defined high frequencies, while a vented dual voice-coil woofer blends the midrange automatically. This design creates accurate stereo imaging from one ceiling location, making it especially effective in smaller rooms or areas where installing multiple speakers is not practical.
Wide Dispersion for Even Room Coverage
Engineered for broad sound dispersion, the RC80i ensures balanced audio coverage throughout the room. Whether you are positioned directly beneath the speaker or off-axis, the sound remains clear, detailed, and immersive—ideal for both background listening and focused entertainment.
Engineered for Reliability and Acoustic Precision
The RC80i uses a combination of advanced materials and intelligent design to deliver consistent, long-term performance:
. Lightweight blue polymer cone for controlled bass and excellent damping
. Computer-modelled butyl rubber surround to minimise unwanted resonances
. Open-back design that uses the ceiling cavity as a “virtual enclosure” for enhanced low-frequency response
. Timbre-matched tuning for seamless integration with other Polk Audio speakers
Discreet Design for Any Interior
With its paintable, low-profile circular grille, the RC80i blends effortlessly into any ceiling. The speaker is designed to remain visually unobtrusive while delivering powerful audio performance.
Durable construction materials, including rust-resistant hardware and moisture-tolerant components, make it suitable for high-humidity environments such as bathrooms and enclosed porches (not intended for fully exposed outdoor use).
Simple and Secure Installation
The RC80i is designed for hassle-free fitting, featuring:
. One-cut, drop-in installation
. Precision flange for a secure fit
. Perfect-fit cutout templates
. Compatibility with pre-construction brackets
This makes installation straightforward for both new builds and retrofit projects.
