I still love my Klipsch RB-81i's, their hugeness and mass (27+ lb/ea!) making the Dayton SSBM24 stands they now sit on a tad top-heavy. The 6.5" LF version, RB-61ii, doesn't give up much spec-wise, on paper, and is a better price ($330/pr - Amazon & Klipsch). Placement is easier, too, as both are front ported.
