Found this quote on Ask.com-
("In fact, in the late nineties, I used a much-modified version of this same Japanese silk-dome driver in designing the M1 Active speaker for Alesis Studio Electronics. Staying at roughly $4 over its 25 year life span that particular tweeter is what has made me a die-hard soft-dome devotee"). Of course I just put a couple of spiders next to my silk dome tweeters hoping they will make the necessary repairs.:)
24 hours in a day ... 24 beers in a case ... coincidence?
