Bowers and Wilkens built and build speakers of sustainable top quality. The same goes for the speakers offered here. They play still like new and will continue to do so for a very long time if used in a normal fashion. I could find little information, but given my experience I estimate the power to be around 100 Watts at 8 Ohms. and the frequency range of 30-25,000 Hz. The titanium tweeters are in top condition as well as the rubbers of the woofers which are still nice and supple and show no damage. They really do sound great. The boxes have only minor signs of wear and the front side is still in very good condition. The frons were so bad that this would affect the whole. Without fronts they look great and that really brings out the best in them. Please see photos for further details. Total weight will be just under 20 kg. They will be packaged carefully and sent by registered mail.
