Questions never stop ever, it seems.

Hello All,  is there any point, any discernable advantage, to go to the hassle of including your subwoofer in the signal path of a bi-wired speaker system? Assuming you have enough connections to pull it off or it's even possible.

As opposed to the more normal thought of using the hi pass filter in the subwoofer by running the signal out from the preamp to the subwoofer then running the subwoofer out to the amplifier.

I don't really see a clear way to do both, bi-wire and use that hi pass filter and maybe even potentially blowing everything into orbit if you connect things wrong. Any opinions or ideas? Thanks.

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.

 If it's crossed at 80 and a 6 or 12 db crossover is used, it is still going down to 30 hz.  The taper on the roll ON (not off) is still from 20 or so all the way to 80 and 80 begins to roll OFF from there @ either 6 or 12 db per octave. So running full range can work but most folks don't like the sound SIMPLY because the timing issue from the mains can't be delayed as easy as the DBA or Swarm system..

I've tried it with every system I've ever used or owned.. I gave up all the way 15 years ago. NO BASS in the monitors. It may be there but I don't use it OR I swap it for MB couplers..

Still you got BASS in the monitor cabinet.. It cannot be timed correctly..
The best you can do is DELAY the signal from the mids and highs...

I also understand the way people blend  their DBA is all important. The SQ is usually a lot better. USUALLY folks STOP there and call it good, because it is good. BUT for me I wanted BETTER.

No BASS in the monitors.. ZERO... NOW the monitors are 2/3 narrower because of it... AND they do actually disappear in a room a whole lot easier..

It is like being in the maestro position all the time not some of the time..
