Better Bass, Enhanced Tweakability, Invisible Rectangular Speakers

Available in a dual-driver 21" model and a 15" single-driver model, these two advanced TCi Series Speakers deliver premium performance worthy of your existing RTiA System. Built-in PowerPort Bass Venting enhances the designed-in Infinite Baffle Tuning to defeat performance-robbing turbulence and reveal surprisingly deep bass response. A Boundary Switch and Tweeter Level Switch allow you to tweak performance to suit your room environment, guaranteeing the most spectacular, absolutely invisible sound.

• Use these TCi Series In-Wall Loudspeakers to complement and enhance your existing RTiA Series listening set-up. Matched materials and components ensure smooth, voice-matched response.

• Patented Dynamic Balance^® Technology ensures lower distortion, so the lightweight, durable Polymer Composite Cones deliver excellent mid-range clarity. Infinite Baffle Tuning enhances lower frequency response, while professional crossover networks blend the two into smooth, musical Polk Audio sound. Use the Boundary Switch to perfect the response in "more reflective" rooms.

• Aimable 1" Silk Dome Tweeters ensure clear detailed highs without fatigue. Aim them to enhance imaging and customize the sound to your installation situation. Use the Tweeter Level Switch to further adjust the highs for optimum performance according to your specific room acoustics.

• Patented PowerPort^® Bass Venting is built in to these TCi models to cut turbulence and distortion. In conjunction with the Infinite Baffle Tuning, this really punches up bass response, for solid, surprising bass (especially from an in-wall speaker).

• Paint The Powder-Coated Aluminum Grilles to match any wall.
