Mains for Home Theater?
Cerwin Vega CLS 215's....Cant be beat for HT. I run 6 of these bad boys and you just wouldnt believe the Movie sound they produce. Ived owned ML's, Legacys, Magnepans, Paradigms, etc..and for HT, these will spank them. Think clean loud sound with a SVS Ultra per speaker.
If you want 2 channel, there still pretty good, but not a hi end sound. For under 1k, my pick would be Paradigm 80 v2 out of your options. For my 1k, some Magnepan 1.6's
