[I need help finding a 10.5 horn]

It looks like I damaged one of my 10.5 horns(is this common[:^)]). I have a 2db difference in sound level between the left and right speakers. Highs above 10k are suffering also. Where is a good place to purchase one. Ebay??

Thanks in advance.

[Is there any hope for my old speakers?]

I moved into a new house and want to setup a HT in a poorly designed(not by me) media room. I own 10.5's, S5's, and a c5. I have to use the 10.5's in another room (they won't fit in this room) so I need to buy new mains. I plan on using a Denon 3801 so I was going to use the c5 as center & the s5's as surrounds. I need to buy rears for the 6.1 format.I have a 9" width on the wall sides I can mount the mains or there are also two shelf locations for the mains @ 31" & 72" high. The center has to be @ 72". The speaker matching chart doesn't have any older speakers listed. Is there any hope of me being able to use my old speakers with newer ones? OBTW I love the Klipsch sound.
