The Klipsch THX-504-L is a high-performance in-wall loudspeaker engineered to deliver cinema-quality sound in a discreet architectural format. Certified for THX Select performance, it reproduces movie soundtracks, music and gaming audio with the precision, scale and dynamic impact expected from Klipsch’s professional theater heritage.

Its four 5.25-inch Cerametallic™ woofers provide fast, controlled low-frequency extension and articulate midrange reproduction, allowing dialogue, effects and musical textures to sound clean and lifelike. These woofers are paired with a 1-inch titanium compression driver mounted to a Tractrix® horn—a hallmark Klipsch technology that offers high efficiency, low distortion and exceptionally accurate dispersion.

The result is a sound presentation that is bold yet refined: deep, controlled bass, a transparent and expressive midband, and immaculate high-frequency detail. Whether handling explosive cinema dynamics or the subtlety of acoustic recordings, the THX-504-L remains composed and engaging at all listening levels.

Its sealed backbox enclosure ensures consistent performance independent of wall cavity variations, delivering repeatable and predictable acoustic behavior. The magnetic grille can be painted to match any décor, allowing the speaker to virtually disappear into the room. Designed for versatile use, it works perfectly as a left, center or right front-channel speaker, as well as a high-output surround in advanced home cinema configurations.
