Polk Audio 70-RT 3-Way In-Ceiling Speaker – Vanishing Series

Discrete ceiling cinema sound with bold, full-range performance

The Polk Audio 70-RT 3-Way in-ceiling speaker brings room-filling sound to your space without drawing attention. A compact 2.5 inch midrange, a 7 inch sub, and a 0.75 inch dome tweeter work in harmony to cover a wide frequency range. Built with Dynamic Balance and Polk's patented Power Port technology, it delivers deeper bass with less turbulence and distortion, helping music and movies feel more immersive while keeping the acoustics smooth across listening zones.

Engineered for integration and aesthetics

The wafer-thin grille is magnetically secured and paintable, so it can blend into your ceiling as if it wasn’t there. The finish remains nearly transparent, preserving clean sightlines while preserving dynamic sound. The 70-RT can pair with Polk RTi speakers for seamless blending between built-in and traditional setups, offering flexibility as your room evolves.

• Perfect Fit templates, a precision flange, and available pre-construction brackets simplify mounting
• Patented Rotating Cam system provides secure, vibration-free installation

Performance details that may impress

With a frequency range from 34 Hz up to 27,000 Hz, the 70-RT aims to deliver deep bass and crisp highs across a wide listening area. The three-way design is intended to offset reflective surfaces, helping maintain clarity even in lively rooms. The Power Port bass venting reduces air turbulence for smoother overall bass behavior, which can enhance the feel of movies, games, and music without overpowering the space.

• 3-way driver array includes a 2.5 inch midrange, a 7 inch sub, and a 0.75 inch dome tweeter
• Power Port bass venting supports deeper bass with reduced distortion

Decor-friendly, easy to install, amazing by design

The center of room sound comes from a speaker that vanishes into the ceiling. The wafer-thin grille can be painted to match your decor, while the secure mounting hardware helps keep the speaker steady and acoustically stable. Whether you’re upgrading an existing setup or building out a new theater, the 70-RT is designed to be a flexible, visually discreet solution that still delivers engaging sound for cinephiles and music lovers alike.

Ideal use cases

Perfect for home theaters, living spaces, or multi-room configurations where you want immersive audio without visible hardware. It works well with other Polk products to create a cohesive surround system that can adapt as rooms change or re-arrange furniture over time.
