I also plan on installing an IB sub, the head guru (Thomas) over at the "Cult", suggested to me that one's L/R speakers should go down an octave below the sub' X-over point. So set at 80 Hz, the mains should go down into the 40 Hz range, in which both the 60s and 100s should work.
What improvements/ compromises are you getting between the 60s and 100s? I feel the midrange / bass could be improved on the 20s, hoping that the sealed design of the 570 will better them.
The 60s would be the same height as my 20s are now on my DIY stands (We have one of those sink into leather couches). The only advantage I could see getting the 100s would be if the midrange /bass is more detailed and balanced. Is this the case? Also, is the horizontal dispersion about the same? Because of windows on each side of my RPTV, I have to space the L/Rs 8' apart, which is pushing it for the little Studio 20s. Problem is, this also puts one of them as close as 20" to one side wall. That doesn't seem to effect the 20s, but maybe using something as big as the 100s could cause boomier bass?
Just stumbled across this thread and I should be able to help with your questions.
All of the Paradigm speakers within a given line (Studio, Performance, etc.) are "voiced" to sound the same, the main difference will be low frequency extension and overall output (loudness) capability as you go up the line. Any of the speakers within the studio line will work well together.
About the 570 center. The 570 is much better engineered than the 470 when it comes to off-axis frequency response. While the 470 and 570 will sound very similar when you are sitting right in the sweet spot, the sound will remain more consistent with the 570 when you sit to the left or right, all because of the additional 4" midrange driver in the 570.
Again the main difference between the 60's and the 100's is that the 100's will have more extended bass and they will play louder. The 100's might also have a slight edge in the midrange if the two speakers are being played full range at highish volumes. If you plan to cross the 60's over to a sub, the advantages of the 100's virtually disappear. However, either speaker will be a step up from the 20's. The additional drivers in the 60's and 100's results in a more effortless sound. The 20's are really best suited for low to medium volumes and small rooms.
Now for the most important part. Yes, I believe there is a very good chance that you will run into trouble with the 100's being close to a side wall, but not because of the horizontal dispersion. Bass is essentially omni-directional, but the proximity of the bass drivers in the 100 to any wall will reinforce certain bass frequencies. I don't want to get overly technical, but the bottom line is that you should audition the 100's in your home before committing to them. If you can't do that, go for the 60's.
The truth is that I learned the hard way. I used to own the Paradigm Signature S8's (essentially a high-end 100) but had to sell them and get the smaller S4's because I had a set-up constraint very similar to yours. I get better sound with the smaller S4's paired with a sub than I did the S8's, all because of my room.
