Hey all. I am setting up a 5.1 HT system in my family room.
What I want is this.

Harman Kardon AVR-130Z 5.1 Reciever.
Athena Technologies BS-2 Bookshelfs Front AND Rear.
Center Speaker? I dont know yet! LOL! What should I get?
Sub.... Dont know that either.

Are big floorstanding speakers needed up front for HT use? Will the 2 sets of bookshelfs and a good center and sub be just as good?

My room is 15X12 so not a huge space.

Im on a bugdet of $1000 USD maybe $1500USD tops. Thanks for any help.
