I recently purchased a used pair of Definitive Technology BP30 speakers, which were missing spikes, side extensions (which add stability) and the owner's manual. I contacted Definitive Technology regarding the possiblity of ordering these items. Definitive Technology sent all of the missing items to me at no charge. Such exceptional customer service deserves recognition. The BP30 speakers matched with a CLR 2000 center were a significant upgrade from the BP10 (original model with fabric tweeter) speakers and CLR1000 they replaced. Bass response, intelligibility of dialog and imaging are all improved.
