Get to know this product.

The C-SUR In-Ceiling speaker uses two 5 ¼-inch (135 mm) woofers and two 1-inch (25 mm) tweeters in a unique 5.1/7.1 dual mode configuration that allows the installer an interesting option. Because each woofer/tweeter pair has its own crossover and input, a single CustomSound C-SUR can be used for both the surround and surround back channels providing an ideal solution for a 7.1 theater in smaller rooms. The CustomSound C-SUR is also an excellent "height channel" speaker because of its diffuse sound fi eld characteristics. This is a speaker that helps pull the sound "off the walls" to create a really immersive experience.

PSB speakers are cherished for their true-to-nature sound—a sound that is neither hyped up to sound momentarily impressive, nor dulled down to blend into the background ambiance. Instead, PSB engineers use over 40 years of acoustic research and experience to create products that sound exactly right, speakers that disappear, leaving only musical expression in their wake. With these new designs, PSB has taken the advanced driver technology developed for the Imagine Series of bookshelf and floor standing speakers and adapted it for the unique requirements of custom installation. The result is a nearly invisible presence, both visually and sonically, that redefines how music can sound in the custom home.

Unlike other In-Wall speakers whose performance is compromised by the very wall into which they are installed; PSB includes a superbly engineered enclosure that ensures the acoustic integrity of the design in every installation. This truly rigid speaker baffle is essential for resonance-free sound and makes it possible to get a predictable high quality result in every installation. The computer-modelled enclosure has exactly the right internal volume to match the drivers to deliver high sensitivity combined with excellent bass extension and quality.
