Something wrong with my high level inputs? This is bizarre! Need sub experts!

[Vedder323]

Alright, this is friggin bizarre. So... last night I tried what friend suggested (connecting my sub and speakers in parallel (both connected from the amps speakers outputs) and the sound stage completely changed... I cant figure out what the hell is going on... its really baffling!

If I connect to the high level inputs on the sub and also use the high level outputs from the sub to my speakers, the sound stage is very confusing and not focused... it sounds over the top WIDE and the vocals are NOT centered at all.., if anything, they sound like they are all around me, and the instruments sound like they are panned extremely far left and right.

If I connect the sub and speakers both to the speaker out from my amp but dont use the subs high level "output" to my speakers, the sound-stage becomes focused and to my ears "correct". The vocals are dead center in the room the way they are supposed to be.

What the heck is going on here?

We need to know which amp, subwoofers, main speakers ... etc ... to help out with this. :yes:

Sounds to me as though the high level output from the sub somehow got wired out of phase.

Or the high level output from the sub has a poor quality capacitor that is used to filter out the low end. You never know what you are going to get when you use the high level out from the sub.
