FLYRED

I have buy a ksw-10, i have already a amplireceiver Denon avr 3802, two Monitor audio Bronze B4 to front, a Monitor audio centre to centre canal, 2 polkaudio r30 on the surround. My problem is: the ksw-10 does to be connection ( i ahave a single subwoofer cable ) to the input Righ or to the input LFE ? On the denon avr 3802 i have a single output for the subwoofer. In the setup of the denon 3802 is is better to choose for the output sobwoofer, LFE+MAIN or LFE (only ) ? The ksw-10 is in a position to piloting all the LFE sound or is better to leave also the frontal diffuser the sound of the low frequencies? Note the Bronze B4 is a 2.5-way floorstander. The ksw-10 it has the power necessary in order to pilot all the vlves in LFE? please excused my English bad one
