Less expensive alternatives to Klipsch Heritage Cornwall IV?

Hi,

I'm no audiophile, listening to mainly rock/symphonic metal and classical. 

Recently listened to some Frozen Crown and Dragonforce on a friend's Klipsch Heritage Cornwall IV. Of course it was amazing. But, I don't know what I don't know. I'm looking for a set of speakers that have similar (may not be as "good") characteristics as my friend's, and don't cost $7500. My room is about 20' x 15', amp is an old Pioneer Elite. Any directions as to where to search for that set of speakers are much appreciated. 

I did a Google query, and the following names came up: Klipsch Heresy IV, Klipsch Forte IV, Polk Audio R700.

Thank you,
