Connect passive Subwoofer to Behringer a800 via XLR?

[Doodski]

If I connect the active sub in between the speakers don't play bass anymore?

What active sub do you have?

What active sub do you have?

I found a "Cambridge SoundWorks SW-320" on the street.

So I cant connect a passive sub and passive speakers to the amp at the same time, right?

I think you can when the passive speakers and passive sub are all 8 Ohm. When they are 4 Ohm you can't use this trick.
Most likely the speak-on and binding posts are parallel.

Connect the passive sub to the binding posts and the passive speakers to the Speak-on outputs (by using speak-on connectors)
You cannot adjust levels between speakers and passive sub.

A computer 2.1 sub speaker setup.
Most likely very weak output.
Try the passive subwoofer first.

Sub is 6 Ohm, Speakers are 4.

Sub is 6 Ohm, Speakers are 4.

That would be 2.4 Ohms in parallel. Not good.

As Doodski mentioned ... not a good idea in this case.

ok thx

update: I could get my mobo to recognize the blue jack as a subwoofer output in a 5.1 - 3 setup. It delivers only lowest freq to the woofer and probably cuts out some of them for the speakers. I guess that's the best solution. nice.
