My current stereo setup has two RTi4s and a PSW 505 sub, which I am happy with. However, I came across the Monitor 60 Series II speakers online for a very reasonable price (about 1/3 their MSRP). Musically speaking, would I benefit from substituting the M60s for my current RTi4s? The RTi4s perform well with music, as others have noted. I know the drivers are the same size in both speakers, as well as the tweeters (I believe). I do have the M70s in my home theater setup, so I have a general idea of what the Monitor floorstanders sound like. But I have never heard the M60s before (obviously less bass, though). Thanks for anyone's input.
