I have any opportunity to buy a set of Klipsch KG 5.5's for $300. Really good price. However, these things are 'yuge'! Like 70 lbs each. I'm wondering what improvement I'd get over my dependable Klipsch KG 4's. Any opinions?
Current setup:
Marantz SR7500
Klipsch KG 4 - front
Klipsch KG 2.5 - rear
Klipsch KV3 - center
