My room will be on a second floor, so hopefully I'll be able to find some way to deal with tht modes.

Do the cornerhorn plans come with plans to make the little cabinet for the horn shown in the drawing on this page? http://www.pispeakers.com/CornerHorn.htm

I have no experience with cornerhorns, so I am wondering how their imaging is with the speakers playing indirectly at you is. Also, how do I find out the ideal listenig position for the Theater 6Pi's if they were in the 11ft apart corners? Thanks.
