Right on Pat- I've seen split LSI's in:
raw birch, no trim
rounded over corners, rectangular top sections (Roger has these)
rounded over corners, trap top sections
pebble painted with aluminum trim (I've owned these, now Rplace has them)
black glass with aluminum trim (no such thing as black glass without aluminum trim btw) (in my shop right now)
Klipsch NEVER used rat fur on these (anything you might see like this is aftermarket)
