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 loudspeaker, whilst the Kevlar midrange driver sounds both warm and clear. The Nautilus inspired tweeter combines fine detail with relaxed neutrality.
