In order to have the subwoofer active, you have to set the Polk's to small -- otherwise, the bass management will send everything to the mains. The -3dB point on the RTi12's is listed on Crutchfield at 30Hz ("frequency response 30-26,000 Hz (-3dB) "), so I'd recommend experimenting with both the 40Hz and 60Hz crossover points. There is a rule of thumb that I've heard several times that suggests setting your crossover point at twice the -3dB frequency, which is why I suggest trying the 60Hz point out. In fact, the -3dB point on my Studio 60's is 30Hz and I'm using the 60Hz crossover with them.
