Questions never stop ever, it seems.

My front speakers amps are connected with XLR-type analog connections from my preamp. The sub is connected to the extra RCA-type L and R analog outputs from the same preamp.

The front cabinet's roll-off in the mid-30Hz range. A SVS Ultra sub is set-up to play from 31Hz and below in the sealed mode. This minimizes any frequency overlap between the SVS Sub and 15 inch bass drivers in the front cabinets. 

Subs like REL’s mentioned earlier do sound great connected to the high-level speaker leads because they share the amplifier's sound character with the front stereo speakers.     

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.
