Hey guys, I don't want to get off topic but there was a discussion in this thread somewhere a long while back about determining polarity and correct sub phase.
It started out like this: Here's a method of determining polarity stolen, er, borrowed from another forum thread.
1. Reverse the polarity of the left speaker by swapping it's leads.
2. Start playing your pink noise source into the speaker and sub. You will want to disconnect all other speakers temporarily for this test.
There is more to follow that I understand, (forgive my ignorance), I'm lost after step two. I'm assuming the pink noise generator is the AVR, correct me if I'm wrong. How do you get the pink noise to play through left speaker and sub simultaneously? I told you to forgive my ignorance. Here is the rest of the borrowed thread.
3. With the RS SPL meter fixed at your listening position (and having it set to SLOW speed and C-weighting), note the the SPL reading when the phase is 0.
4. Start changing the phase and note the the SPL readings.
5. Pick the phase angle that gave the minimum SPL reading.
6. Reverse the speaker leads to their normal positions and reconnect the rest of the speaker system.
******Since the needle on the SPL meter usually bounces around a bit while measuring bass frequencies it's often easier to find the minumum SPL using this method instead of trying to find the the max SPL.
Guys I really appreciate your feedback here and apologize for my ignorance of subject matter, I'm embarrassed to ask but I'm not to proud to admit when I don't understand something even if it's probably as straight-forward an answer as this one.
I have been chatting with Jim quite a bit lately, have no problem getting a hold of them, Jim is very informative and helpful and quite the gentleman as well, Tom and Jim make for one hell of a team, so glad I was an early adopter to PSA. I have wasted so much time, effort and money prior to finding PSA. Thanks guys for your patience and understanding, I look forward to the replies.
