Sooo my dad picked up a system of Klipsch HD Theater 600 5.1 Surround speakers at a garage sale brand new and sealed for $50 and I had already bought the Logitech Z623 2.1 Surround speakers a few weeks earlier (I am very impatient at times esp. when building a PC). What I want to know basically is which speakers have better sound quality? Just a note: I am aware the Klipsch speakers brand new are $600 and the only reason I am posting this is because I'm not entirely sure if I'm getting what I pay for in a 5.1 speakers esp. by Klipsch.
