floor standing speakers for surrounds?

Mtrot is right with one addition, the crossover depends most on where your sub and fronts blend best. With music you generally want the speakers to run as full range as possible an with movies you want to supplement 80hz and below or 60hz and below with a sub. My Anthem allows me to do different crossovers between music ad movies. If your receiver or preamp allows for that ad well then I would start out with 80hz for movies and 60hz for music in your case.

I am running a pioneer elite 92txh... i bring it down to about -8 on the volume and it is way loud...well not so much way loud as the treble is crazy high and listening to movies at a higher level get a little painful to my ears when the highs hit. the receiver early heats up even after 3 hours of lord of the rings... it has the room correction... i use it.
my dedicated room is 25 by 25. concrete block with drywall inside and comercial carpet.

Dam spell correct.. i ment to write my receiver BARELY heats up even after 3 hours of the lord of the rings movie.

Waste of money. You will never get it 'right'. Check out Floyd Toole's book, 'Sound Reproduction'. He will convince you of the folly of your quest.
