RM 6800 Subwoofer

keppy

I just purchased the RM6800 and was wondering how to wire the subwoofer to my receiver. My old subwoofer just had the LFE input that was connected to the receiver, which is the only subwoofer output I have and no extra speaker outputs from the receiver.

The new polk subwoofer has the left and right line inputs. I'm assuming I could wire from the LFE input from the receiver to either the left or right line input or buy a Y-connect to wire to both L and R line inputs. I've wired the L and R front speaker outputs from the receiver to the subwoofer and then from the subwoofer to the front speakers as Polk's diagram showed. Right now I have the subwoofer set to "On" in this set-up, but in the help section it said for the RM series the subwoofer should be set to "Off". If anyone know the best way to set this up, I would appreciate it. Thanks...

I too have a RM6800. I have a harmon 340 receiver. I just used a subwoffer cable and wired the other speakers directly from the receiver. I works fine.

Don't use a Y connector, connect your other speakers from the sub like you described. It will work fine.

Hello, my impression with Polk Method, don´t work fine. The bass output was less powerful than traditional method and very noisy. I´m actually running from the sub out with a good Neotech cable with Canare Rca´s and works very fine. Anyway, if you go with speaker level method set the sub to off/no. If set to yes you will loss the bass frequencies. Try both method and decide what is best for you. Cheers

Oh! Don´t forget to set all speakers to large with speaker level method.
