Blackie,
No reason other than looking for the best possible center channel. A pair of 805's are the same price as the HTM-1 and thought, hmmmmmmmmmmm, what if.......
Just thinking out of the box as they say.
I like the HTM-1, I have one now, but curious of the 805 route. Some people use one above and one below a screen. I now use a screen and wondered if there is a great deal of improved sound.
