Niles® CM7SI 7” 2-Way Ceiling-Mount Stereo Input Loudspeaker (Each)

Niles® CM Loudspeakers deliver an uncompromising combination of designer oriented aesthetics, superb sound performance, and ease of installation. Stereo Input loudspeakers are optimal for spaces where multiple speakers are not practical. Glass fiber woofer cones with dual voice coils and dual UltraSilk® soft dome tweeters on a stereo imaging array create spacious stereo sound from a single speaker.

Designer Aesthetics

Magnetically attached MicroThin™ speaker grilles ensure a clean, virtually invisible appearance that blends with the room’s aesthetics. Optional square grilles are also available (sold separately) for added design flexibility.

Superior Sound Quality

Precision tuned and voiced fixed woofer ceiling-mount loudspeakers provide graduated performance for all types of applications. Whether you are listening to background talk radio or a complete orchestra, Niles CM series delivers optimal performance and reliability.

Installation Ease & Confidence

Three patent-pending spring tensioned mounting clamps permit quick installation and compensate for uneven mounting surfaces and varied environmental conditions. Weather-resistant construction enables installation in moist areas, such as bathrooms or outdoors under eaves. What’s more, you can install with confidence; these best-built loudspeakers receive the best protection they deserve under the coverage of the Niles Lifetime Limited Warranty.

7” Woofer

The CM7SI’s integrated woofer/frame assembly increases the cone area for deeper bass than competitive speakers of the same diameter and employs a 7" glass fiber woofer cone with a curvilinear profile for smoother sound and less peaking at high frequencies. The glass fiber dual voice coil woofer reproduces left and right channel inputs from a single speaker, while the high quality butyl surround increases sensitivity and preserves durability.

Dual 1” UltraSilk® Tweeters

Equipped with dual 1” fluid-cooled UltraSilk® tweeters, the CM7SI provides wide dispersion for clear and detailed high frequencies. What’s more, the bridge-mounted Stereo Imaging (SI) tweeter array directs the high-frequency sounds from both the left and right channels at opposing angles to preserve stereo separation.

Weather Resistant

Weather resistant construction reduces installation limitations and provides unique solutions in moist environments or outdoors under eaves. And to top it all off, the magnetically attached, rust-resistant grille covers install quickly and provide a low profile look suited for any application.
