Currently i have the Klipsch HD300 connected to my Onkyo txsr701 system for my surround sound. But i want to upgrade because im somewhat of an audiophile. The HD300's dont pack enough bass for my personal taste while watching action movies and such. Im thinking of upgrading a pair at a time because im a college student with a small amount of cash. Probably no more than $500 a pair. Can anybody help me pick some high quality speakers for my budget? Thanks!
