Information Sheet Imagine a speaker that’s no more obtrusive than a standard 50mm (2”) low voltage downlighter, yet powerful enough to flood a sizeable space with high definition sound and designed to smoothly integrate and architecturally match with existing downlighting. Impressively vocal and superbly balanced, the Ci50R is a masterpiece of intelligent miniaturisation and thanks to the design and specification of the drive unit, a deceptively accomplished performer in real rooms.
