One speaker, multiple applications

Like all PSB speakers, the CustomSound C-SUR is prized for its true-to-nature sound. It is also highly versatile, offering several placement options for creating an immersive home theatre experience. Capable of handling 150 watts of amplifier power, the C-SUR is the robust yet discreet in-ceiling speaker your home theatre sound system deserves.

Bring big sound to small rooms

The CustomSound C-SUR in-ceiling speaker uses two 5¼" (133mm) woofers and two 1" (25mm) tweeters in a unique 5.1/7.1 dual-mode configuration that allows for an unusual installation option. Because each woofer/tweeter pair has its own crossover and input, a single C-SUR can be used for both the surround and surround-back channels, providing an ideal solution for a 7.1 theatre in smaller rooms.

Create the ideal soundstage

The CustomSound C-SUR is also an excellent height-channel speaker because of its diffuse soundfield. This speaker helps pull the sound "off the walls" to create a truly immersive experience. Combine the C-SUR with other speakers in the CustomSound line, such as the C-SUR and W-LCR2, to create a superb home theatre surround sound system.

Designed for acoustic integrity

Housed inside a meticulously engineered enclosure that ensures the acoustic integrity of the design in any installation, the CustomSound C-SUR is uncompromising in its performance, both visually and sonically. As an added benefit, the enclosure reduces sound transmission into adjoining rooms. This is the concealed-speaker system your home is waiting for.
