I have the latest large floor standing Ushers with the DMD tweeters and they are so much better than their earlier BE tweeters. The BE tweeters were a large step up over their prior silk tweeters and the DMD are a large step up from the BE. The DMD can go up to 40+kHz and sounds more cleaner.
beryllium vs diamond
Hi guys, today's technology has brought us a new type of tweeter made of diamond or beryllium. Do you know what are the strengths and weaknesses of diamond vs beryllium? Which one is the more expensive? Has today's dome tweeter better resolving power than the venerable electrostat? Jim Thiel once said that dynamic designs will be getting better all the time and will probably surpass electrostatic designs.
