Thanks to this site i've just upgraded the tweeters on my fortes 1s which i bought long ago at henrys radio in los angeles, must of been 1986 or 1987...I also have a single forte 2 which will also be getting a titanium upgrade,not to mention crossover upgrades or rebuilds from bob crites. Over the years I've used it as the center channel in home theater.Only recently back into music, finding a single owner jbl sa600 amp had to be a sign....
