Simple question. Should I expect a marked improvement from my Qb's, which I love, to the RS6 Kappa? My Qb's are recapped and original but have emit K tweets. The Kappa 3 ways have the same tweets, polydome mids with, I believe 902-3061 woofers. I'm going to demo the 6's tomorrow. Obviously I can't AB test until I get them home.
