"A diamond is forever, so the saying goes. And B&W has good cause to believe its new reference speaker range, named after the famous gem, will stand the test of time. The heart of this design is an all-new 25mm pure-diamond dome tweeter, whose superlative physical properties eliminate almost all the inherent problems of alternative hard-dome materials. In the 803D the diamond tweeter joins a trademark B&W Kevlar midrange unit, and three 180mm woofers featuring stiff, light Rohacell. The sound a beguiling combination of full-bodied lows, warm midrange and smooth treble marks a welcome departure from the traditional B&W approach."
