Product Overview
The KEF Ci50R Soundlight is a discrete application ush mount
speaker designed to simulate the appearance of conventional
2 inch low voltage lighting systems. The speaker driver is only
50mm in diameter yet powerful enough to ll spaces with
superbly balanced sound and clear vocals. The Ci50R is available
with white, chrome, brass or brushed steel bezels to match
most common low voltage lighting systems and installs quickly
with the use of self-tensioning brackets. Engineered to be
discrete, the Ci50R leverages KEF’s acoustic expertise to deliver
an audio experience suitable for high quality background music
and voice announcements in common multi-room systems,
lounges, retail stores, and boardrooms.
Key Features
Discrete Appearance – At a total diameter of just 80mm,
including the trim ring, the KEF Ci50R blends seamlessly with
traditional 2 inch low voltage lighting systems delivering the least
obtrusive premium audio solution possible.
Multiple Bezel Options – The KEF Ci50R is available with white,
chrome, brass, or brushed steel bezels to match most common
types of interior lighting systems.
Rapid Mount System – Self tensioning tabs make installing the
KEF Ci50R a breeze. Simply drill the opening, connect the
wiring, and slide-in the assembly.
UV Protective Finish – Manufactured using a UV protective
coating the KEF Ci50R is designed to resist fading even when
mounted in environments with direct sunlight.
IP64 Certication – The speaker passed ocial IEC testing to
ensure that splashing water would have no harmful eects on
assembly components.
