Yesterday I went to town on my new AVR, trying out every permutation of speakers, surround modes, etc. to find out what sounds best. I settled on having the front mains and the front height speakers all be identical towers. With the rears, using bookshelf speakers was fine - probably because surrounds are closest to the listener whereas the height speakers are the furthest from the LP of all the speakers. The end result is the front height speakers need to be powerful. The effect is sublime IMO. The first time I heard a 'height' effect of a fly-over make me realize that until now movie/music listening has been strictly 2 dimensional.
Taking close-mic readings (6" from the tweeter) of each speaker playing various tracks in PLIIz mode, a pattern emerged. The center channel pulls a lot of duty - let's say it is running at 100db average. The mains and the front high speakers are all cranking out somewhere around 96db and the surrounds are a mere 92 db average. The advantage is the height channels blend the center in a way that is far more natural than what I have experienced in the past. I was a fan of phantom center and 2-channel listening for music. This rig flips the script, PLIIz + THX Music is my new favorite. Totally worth the 12-hour re-arrangement marathon.
The key to front height mode is that the sounds move through the vertical field totally seamlessly. Don't skimp on it, it's the most exciting thing to come along in a while, I cannot wait until movies are properly encoded with height effect. 'The future is looking up'

I myself am very curious how close and DIY'er can come to top level performance at that little of a fraction of the cost.
I know you said you talked to the guys a bit more than I did about using surrounds, and you mentioned a concern that I thought of as well. The "minion" uses a nice B&C driver, but a different CD and waveguide. What do you think the trade offs will be using either the same CD/wave but differently voiced woofers and visa versa. Not sure what your thoughts are on the future, but I plan to add height and wide speakers so the matching qualities are a concern and it would seem a bit excessive to use a 15" main as a height speaker
. On the other hand, the month I have spent in the diy section has led me to the land of excess, which coincidentally you may be in the running to be mayor of:D
