About the JBL Studio 6 66LCR
Versatile in-wall sound from JBL
Versatile in-wall sound from JBL
Some audio enthusiasts prefer to use the same model speaker for each channel of their custom-installed home theater, so the tonal quality stays as consistent as possible for sound effects moving from channel to channel. If that sounds like you, consider JBL's Studio 6 66LCR for seamless, voice-matched surround sound throughout your room.
Install this high-performance in-wall speaker vertically as a left- or right-channel speaker, or horizontally as your system's center channel. Its drivers are specially configured to sound great in both orientations.

A unique driver array delivers superb sound
JBL uses horn-loaded compression drivers in speaker arrays at large concert venues — they're able to fill space with clear sound in a way a standard dome tweeter can't. This same technology is used in the Studio 6 66LCR for expansive, crystal-clear high frequencies.
JBL's proprietary HDI (High Definition Imaging) waveguide technology helps the compression driver deliver optimum sound quality throughout your room. Dual 6-1/2" PolyPlas® woofers complement the compression driver, serving up crisp bass and articulate midrange with movies, TV shows, and video game soundtracks.
Adjust the sound to your space
The Studio 6 66LCR has two front-panel level controls that let you adjust high- and low-frequency output to best suit your room's acoustics. Use them in conjunction with your home theater receiver's auto-calibration system to tailor the sound to your space.
