Surprisingly Big Sound.
The Vanishing Series 70-RT features a unique 3-way driver array that produces big, full-range performance from a deceptively small in-ceiling speaker. The 70-RTs grille can be painted to match your décor, and will blend in perfectly with their surroundings.
- 3-way design

Patented Polk Audio technology and construction techniques produce powerful, deep bass performance, especially when you need it most.
Patented bass venting design smoothly transitions air flow, eliminating turbulence and distortion, for deeper, more efficient bass impact.
Dual Band-Pass Bass Ports
Smooth funnelling for low frequencies around the driver array eliminates "chuffing" for full-range blending, broad coverage and deep bass.
Vanishing Series built-in speakers feature Polk's exclusive wafer-thin Sheer-Grille, a magnetically secured grille that protrudes only 7mm from its surroundings. Sheer-Grilles have nearly transparent, ultra-small perfs, and are acoustically inert, for dynamic, unimpeded sound and more uniform coverage, even in larger rooms.
Reflective Room Compensation
Reflective surfaces in rooms can make sound brighter and cause image distortion. Engaging the Vanishing reflective room compensation feature lowers the tweeter level to compensate for reflective surfaces. Vanishing reflective room compensation is a custom audio control that cuts the level only in the 4-5kHz range, exactly where reflectivity destroys sound quality.
The 70-RT are ideal for use with Polk Audio RTi speakers for seamless blending between traditional and built-in speaker systems.
