Sonance QR-Series Speakers
The Sonance QR-Series speakers feature a small footprint (they
install in a 6¾” cutout) that makes them ideal for locations
where space is limited. Highly musical sound is guaranteed by
polypropylene cone woofers, dome tweeters and quality
crossover components. High sensitivity allows fewer speakers to
cover a larger area in distributed audio applications, making
them perfect for background music applications.
With paintable aluminum grilles and a small diameter that let
them practically disappear into the décor, Sonance QR speakers
bring high-quality entertainment to life in places that present
installation challenges.
Features:
• 5¼” Polypropylene cone woofer with rubber surround produces
strong, low-distortion bass in a small footprint that increases
installation options.
• Dome tweeters deliver crisp high frequency performance to a
wide listening area.
• Pivoting tweeter (522
QR
) directs sound at listeners for clear
sound even when placement options are limited.
• High sensitivity covers larger area with fewer speakers in 
distributed audio applications.
• RotoLock
®
mounting system makes installation quick and easy.
• Paintable aluminum grille.
• Available QR-Series Flexbracket (part #92175, sold separately)
reserves speaker location and serves as cutout template for 
drywall installer in new construction installations.
