I have a set of rm101 L&R front speakers that came with my rm6880 system. I had hoped I would be able to upgrade to a bigger front speaker like the rm 201 but polk no longer makes them. I saw the R, T and M series which look like a good upgrade with a bigger woofer. I had read somewhere on the forums that they use different tweeters even though they are all 3/4" tweeters. Would the R150 or T15 be a good sonic mach for my RM101's or should I just stick with what I have? I really wish Polk wouldnt have stopped making these because I loved the build construction and sound of this series.
