B&W BB LCR7 User Manual
CWM LCR7
See nothing, hear everything
True 3-way in-wall speakers like the CWM LCR7 are unusual. Featuring cutting-edge B&W technology, the LCR7 features twin
100mm (4 in) mica cone bass drivers, a 100mm (4 in) woven Kevlar® cone midrange driver and a Nautilus™ tube-loaded 25mm
(1 in) aluminium dome tweeter.
The sound of the CWM LCR7 communicates every audio nuance from low bass to extreme treble and from whispering quiet to
sound levels equivalent to live music. The mica bass drivers provide the low frequency snap characteristic of any really good loud
speaker, whilst the Kevlar® midrange driver sounds both warm and clear. The Nautilus™ inspired tweeter combines fine detail
with relaxed neutrality.
