For mid-range and treble, I don't know of any speaker in the $500/pair range that will match the 2030P, when you consider all aspects of it's response(overall linearity + off axis response + energy decay), and most of these in that price range will not have the same build quality as the 2030P.
Did you notice the somewhat lower than normal cabinet resonance? And the substantial, 1.25" MDF front baffle? And the quality of the drivers - the midwoofer having a cast frame and massive motor? The crossover - again - using high power components simply not seen normally.
I know the price forces one to believe it can't be so great. I had a hard time accepting while I was analyzing them.
