Bought this sub to supplement my R-40PM's. I'm still playing with the gain/crossover configuration, but the base travels and has a great punch. This will certainly shake your kitchen glassware and knock you out if you turn it up! I got the y-splitter cable to connect the sub to the speakers because I guess you can get better (double?) output..from one novice audiophile to another.

The bass is fantastic, it sounds great with music, movies and gaming. It blends well with my two R-820F towers, R-34C center and the pair of RP-502S speakers.
