Polk Audio 70-RT Vanishing RT Series 7” In-Ceiling Three-Way Loudspeaker

Deliver full-range performance with the Polk Audio 70-RT. This Vanishing RT Series 7” In-Ceiling Three-Way Loudspeaker is equipped with broad coverage and an extra deep well design with a Cassini oval woofer to create dynamics like no other.

Big Sound

The Polk Audio 70-RT features a unique 3-way driver array to produce big, full-range performance. Listeners will be impressed with the abilities of this deceptively small in-ceiling speaker.

A Perfect Match

Made to match the style and décor of their surroundings, the Polk Audio 70-RT fits any setting. Its wafer-thin painted grille magnetically secures to deliver a transparent dynamic with unimpeded sound.

Power Port®

Patented bass venting is designed to smoothly allow transitions air flow. This eliminates turbulence and distortion, creating deeper, more efficient bass impact.


This Loudspeaker is compatible with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems. Lower tweeter levels also offset reflective surfaces to cut the level in the exact 4-5kHz band where reflectivity destroys sound quality.

Dual Band-Pass Bass Ports

Eliminate “chuffing” for full range blending with broad coverage and deep bass. The Polk Audio 70-RT does this by utilizing smooth funneling for low frequencies around the driver array.

Easy to Install

Perfect fit templates are included along with a precision flange, (available) pre-construction brackets and a patented Rotating Cam. All of this comes together to offer secure, vibration-free installations.
