For whatever it's worth my son replaced his 4.5's with the klf-20's. Then went on to the klf-30's which are really too much for his room (although he doesn't think so). That being said you may not need the sub at all with the 20's or 30's and should be in your price range used.
Want to replace my Klipsch KG 4.2 - recs please-
I chose the Klipsch KG 4.2 speakers back in the mid 1990's because they had 10 inch drivers and were the only speakers that satisfied me for my rock music tastes (I don't listen to classical, even now) They cost about $650 for the pair back in the day. I'm looking to spend about $1,000 used - maybe PSB or paradigm or something that can still convincingly do rock well. 10 inch drivers preferred since i truly believe you can't change physics, for rock you need these - forward firing preferred with no rear ports. (I already have a 15 inch Definitive subwoofer as well and its barely on and barely perceptible but fills in for the ultra low freq really well) Recs please? Rock and roll people please chime in!
