For 50% music,
Automatically polk does not favor among the selected brands, as polk is all about movie experience.
Tannoy highline series again cannot be compared for muscle required, especially for your room size which is huge
Revel, you haven't stated which series of performa? Be or 3? Again not ideally suited for music.
KEF R700, B&W702S2, Sonus Faber Venere S & 3.0 (which have varying impedance & price) are better options for your requirements for music, thought sonus faber is not meant for rock/pop music.
Would suggest you go for the marantz preprocessor & a good multichannel power amp to do justice to the set up & size of the room.
Sub selection will be equally important , in fact factor in 2 subs at least and their costing, good ones are not cheap. Lastly a good source would be must have as without it, all the money spent on the rest of the set up would be colossal waste.
I suggest you to get a system integrator on board to do a proper install & justice to your requirements.
Since you are going to spend a good amount on the set up, why not have some basic automation also to make operation of the HT much easier for you and your family members?
