Need help with two subs

[ParanoidAI]

I think I'm screwed.. I bought two paradigm PDR10(Both w/o phase control). My amp has one sub output, with phase control, but that affects both subs.

I have one sub in front, the other in the back of my room. Is there anyway I could reverse the phase of the one in the back? I've looked for solutions, but couldnt find anything.

THanks!!

Try putting the subs at the mid-point of the side walls, those locations may place them in phase.
If that doesn't work, or the locations aren't possible, connect the subs to the speaker line outs, with one connected +/+, and the other -/+. That will reverse the polarity of one, thus the phase.
The one drawback is you will only have bass output, not LFE output.

Or leave one sub connected to the coax and the other to speaker line, with the reverse connection.

Or sell the subs and buy subs with phase controls.

You might not need to put the subs out of phase, right? How would you determine that?

I think you could do something to the cable to get the conductors switched from the center pin to the outer portion of the RCA connector. It's just a thought. Seems like they have adaptors for everthing else.

I like your speaker line outs + Coax setup.. That way, I would get LFE + all low frequencies from main..

Thanks for the advice!!
That mean I should set front speakers to large right?

Would that work? Reversing a RCA cable??
That would be awesome, and not too hard to do..

Seems like it would work. I just took a look at one of my monster 'sub' cables. It has two conductors and a shield. The shield is only attached at one end making it directional for the people from the planet Zoltar.

I think I would go to the end where it's only the conductors soldered to the connector and swap 'em. Maybe buy an RCA end from radio shack and start fresh. There might even be a phase switch you can buy to take that signal anywhere from 0-180 degrees for the ultimate in flexibility. I know there are people here who know about this stuff.
