I'm ready to buy Aperion speakers as my 5.1 surround sound system for my new HDTV. I will spend about 60% of my time watching HDTV and Blu-ray movies on my HDTV (gaming and music will make up the remaining 40%). 

I am torn between the 4 and 5 series front speakers and center channels. My room is 15 by 22, has hard wood floors, has lots of windows, and has a high ceiling. I have a 9 month old daughter so I can't crank it (my wife wouldn't appreciate that either). I also think that the floor standing speakers will be safer than bookshelf speakers on stands for her. I plan to buy Onkyo 606 for these speakers.

For those of you that have actually heard/demoed these speakers how do they compare? In terms of value, how does each set compare?

I did read one professional review online of the 5Ts that said the 4Ts gave 80% of the performance for almost 1/2 of the price (or something like that). I also read somewhere that the 5C was recommended over 4C if you watched a lot of movies (even with 4Ts as the main speakers). 

 Thanks in advance for your feedback/comments.
