I finally upgraded my SDA SRS 2.3's with the silk RDO-194's and I am extremely pleased with the results. Thanks to all of you who recommended them so highly. I have 5 of the SL 2000's I need to sell now. One of the tweeters was blown when I bought the speakers on e-bay so I borrowed one from my SDA 2's to get them up and running. Anyone out there need these? What do SL 2000's go for these days? I saved the packaging from the new tweets so I have decent packaging to ship them in.
