B&W Signature Diamond Speakers, Pair,Wakame, Limited Editions. SHIPS in special custom made Road Hard cases on wheels, case was made by B&W for these speakers. Limited edition speakers, only 500 pair made. This is pair 56/500. Diamond is a tweeter dome whose reproduction of high frequencies is as near perfect as it is physically possible to achieve. Encased in smoothly sculptured marble, this remarkable driver sits strikingly on the plinth-like cabinet, where it is partnered by our Kevlar® bass/midrange driver. It creates a sound so immediate, so detailed, so textured, you'll want to touch it. There's no finer 2-way speaker in the market today. All drivers are 100% working condition. Some blemish on the speakers. I’ve tried to take pictures of the blems. The lacquer on the speakers is in good overall condition. I am the original owner, and think one speaker might be faded from the sun. Speakers sound amazing and work perfectly!! Sold as is. No returns. Speakers need to ship via professional freight truck bc of cases but will arrive safely. That’s why freight is expensive.
