Nov 19, 2016 I am debating between the RB61 II and the RP160 M 1) I have previewed the lowerend R15M and the RP160M, but not side by side. I like the brightness of the R15M and am curious if the hybrid rubberized horn tweeter of the RP160 changes the tone of the highs. 2) The RP160 has rear firing bass port and the RB61 has front firing port
