LS Series

Custom In-Wall and In-Ceiling Speakers


Polk's exclusive magnetically-secured and wafer-thin Grille

Vanishing Series in-ceiling & in-wall speakers feature our exclusive Sheer-Grilles which have nearly transparent, ultra-small perforations and are acoustically inert for dynamic, unimpeded sound and more uniform coverage - even in larger rooms. Vanishing Series speakers are virtually indistinguishable from their surroundings.

Enhanced Ring Radiator Tweeters

Extended top-end response for incredible details and realistic imaging

Superior imaging and clear, lifelike detail is revealed by superior tweeter technology. With higher power handling, extended dynamic range with higher top-end response, better blending and improved dispersion, the Enhanced Ring Radiator takes performance to a whole new level in the surprisingly affordable Vanishing LS Series.  Plus, the reflective room (tweeter) compensation switch can digitally compensate for reflective rooms without hindering high performance.

Simple Installation

Built-in audio is within reach with easy one-cut, drop-in installation, Perfect Fit templates, a precision flange and pre-construction brackets (sold separately). Achieve secure, vibration-free efficiency with a simple turn of the patented Rotating Cam system.

Power Port™ Bass Venting

Polk’s patented design for smoothly transitioning the air flow from the port into your listening area, eliminating turbulence and distortion, for bigger, more efficient, deep bass impact.

Custom Audio Control

If positioning limitations demand that your loudspeakers be installed closer than 2 feet from side walls, the proximity of the surface can result in a response bump between 50 and 200Hz. This can create boomy sound. The Vanishing wall distance toggle switch is a custom audio control that adjusts the crossover to flatten response and tune out boominess, without sacrificing deep bass response, for more lifelike sound and more flexible placement.
