Designed around our award winning EX floor-standing platform, the new Elite® EX Series not only redefines the entire architectural category, but also now offers an even more comprehensive solution for the most refined of audiophile tastes.

With an experience that blends seamlessly within any environment, the EX Series offers exceptional sound with all but complete invisibility.

Built with only the finest of hand picked materials, our patented Coherent Source Transducer (CST) driver technology offers every home cinema connoisseur the most enveloping and accurate “sweet spot” available today. To fully appreciate our Elite EX Series speakers, they simply must be experienced to be believed.

The benefits of a less visible, entirely in-ceiling installation continue with the equally seamless integration of the S-IC691A. Designed to blend into any home theater or dedicated cinema environment with up to 5.1 or 7.1 channels of angled sound, the full advantages of our CST driver technology are taken a step further by the ability to direct our speakers outwardly toward your listening position as opposed to just at the floor.

And when you combine a 6 1/2" woven aramid/carbon composite bass driver, a 5 1/2" magnesium midrange and a 1 3/16" ceramic graphite tweeter – absolute sound purity is unavoidable. Add features like Treble Contour Control, and all that exceptional sound is at your very fingertips.


All Architectural Loudspeakers are backed by a 5 year limited warranty. Details are provided on the Limited Warranty Sheet included with the product.
