A complete set of DALI Opticon stereo and surround sound speakers. Absolutely RIDICULOUS sound. Will not disappoint any audiophile with the exceptional sound stage and clarity. Ribbon and traditional tweeters on the front speakers and floor shaking bass with the included Subwoofer. Selling as a complete package ideally. Well over £4,000 new. I am also selling a ROCKSAN BLACK stereo amp to drive them if interested, and a Yamaha 7.1 integrated amp.
