Some fun memories rehashed here!! Old Sci-Fi grooviness!
BTW, I agree with you Steve, those concave Focal Tweeters on earlier Wilson speakers were way too bright. Even after they went with some dome tweeters, they made a move to metal dome and it screwed up the sound again.
Now they are back to fabric dome, sounds much better. But still not worth the $.
Focal has kept the concave tweeter, but they have improved the hell out of it IMO....
