Questions never stop ever, it seems.

My apologies I should have given a bit more info. The subwoofer is a Sunfire SDS-12 so I do have the connections and controls on it to as I wish. Meaning I have the preamp outs run into the subwoofer in, followed by connecting the subwoofer outs to the speaker. As I understand it, I am automatically using the subwoofer's hi pass filter this way.

But I don't see a way to run the cables this way, through the subwoofer then back out, that would also include a bi-wire option, right? 

I mean, I'm pretty sure I am correct there. Run the speaker cables in a standard bi-wire configuration or run it through the subwoofer with bi-wire. I've looked over the Net for potential connection diagrams for a bi-wired system that includes a subwoofer in the path but I haven't seen any which makes me suspect it's enormously complex or can't be done.

Right?

audiorusty177,

That is exactly how I have my system currently configured. Preamp Outs to Subwoofer In and Subwoofer Outs to the amplifier itself. That engages the hi pass filter and gives me some control options on the subwoofer but are you also saying the system is now bi-AMPED  not just bi-wired? I'm just trying to make sure I understand here.

Thanks!

Bi-wire has nothing to do with the subwoofer. You are bi-wiring from the amp to the main speakers. The line level goes out of the the preamp into the line in on sub then the from the line out of the sub to the input of the amp. Most subs have a fixed 80hz high pass filter. Bi-amping is when you use two power amps for the lower and upper half of your main speakers. You have it correctly setup the way you have it now!!

It is preferable to run the mains full range and the sub additional to, not crossed over from.

From what I see on the Sunfire website, your sub only has RCA input capability. So you run from your pre-amp to sub OR you run from your pre-amp to sub and back out of the sub to your main amp. The first way does not use the crossover in the sub, the second way does.
