So I'm thinking of expanding in the upper polks, they're all beautiful. I love looking at lots of drivers moving. So I'm sort of drawn to the RTiA9, RTi12, RTi150 quite a bit. But I'm curious, what are the overall sound differences of these polks? Many of them are in the same price range, so it must be a matter of preference I presume. It would be nice to see a little mini-summary of the differences, or comparisons of them, to get an idea of why they exist in similar price ranges.
RTiA9 - How does this compare to the LSi25? And how does it expand beyond the M70?
RTi12 & RTi150 - How do they compare to the RTi9?
LSi15 - How different is this from the LSi25? Any difference really beyond the built in sub and low frequency response?
LSi M705 - Are these basically the top shelf option? How do they sound compared to the RTiA9 and LSi25?
Any basic summaries of their overall sound, refinement?
