I see them on Ebay I will look and from one of my Klipsch favorite sellers.
Does have the V or the just the rectangular plate with Klipsch ??
I have seen them for less $$ so look for a few weeks maybe one of our members has a extra.
-- They are the rectangles -- i will stay on the lookout .. those seem a little pricey
I use a sub in the bedroom with my HII that are on 26" tall stands so the mid horns are at ear level. I should have done this 10 years ago.
