You are wrong. Cozmo is talking about YOU. The phase setting has absolutely no effect upon the sub itself's output. A sub playing a tone by itself at 75dB will have the exact same amount of cone movement no matter where you set the phase. The phase controls how the sound that the sub puts out interacts, acoustically, with the output of the other speakers.

Yet my subwoofer still has a phase control because the phase issues occur at the listening position where the audio waves are being perceived. Phase issues will be different at each listening position as well, because each position is a different distance from speakers/subwoofer(s).

All I can figure is that he MAY be feeling an increase in the sympathetic movement when the 'correct' phase is achieved.

Or, more likely, he is confusing his phase knob and his low-pass filter knob.

nope. it's the outer limits:

There is nothing wrong with your television set. Do not attempt to adjust the picture. We are controlling transmission. If we wish to make it louder, we will bring up the volume. If we wish to make it softer, we will tune it to a whisper. We will control the horizontal. We will control the vertical. We can roll the image, make it flutter. We can change the focus to a soft blur or sharpen it to crystal clarity. For the next hour, sit quietly and we will control all that you see and hear. We repeat: there is nothing wrong with your television set. You are about to participate in a great adventure. You are about to experience the awe and mystery which reaches from the inner mind to... The Outer Limits.

Well there we are, now it's down to alternate realities.

Anyhow IMHO, it's an eyeopener as to how many that post in the AVS subwoofer forum do not understand how to *manually* set up one or two subs in a MC (MultiChannel) sound system, not to mention that many of those in this thread don't both to actually follow-up on what I've accurately stated again and again in this thread.

1st, buy a copy of the best disc I've come across for this is:

"The Ultimate DVD Surround Sound Sampler & 5.1 Set-Up Disc" by Chesky at:

http://www.amazon.com/gp/redirect.ht...&creative=9325

Also read my posts in this relatively short (95 post) thread. All of them are consistent and accurate.

All I can say is what has worked for me for the past 11 years of owning and setting up subwoofers, both for myself and others, have never been disappointed, was said in my first post in this thread, and stands as true as anything. There is NO NEED for 'setup' discs. There is no need for specialized equipment that can graph your response. The ONLY thing neccessary are the listeners ears. Nothing more and nothing less. Regardless of the 'phase' debacle of what a phase switch actually does, what it all boils down to is what sounds best to the listener. And I quote:

I'm done with the dumb/nonsense posting in this thread.

I'll open up a new thread in the subwoofer forum, that
is on topic to the subject of *manually* setting up 1 or
2 subs, which is what I've addressed in this thread.

Reply there, because I'm done with the dumb posting
in this thread.

Cheers

So you're admitting it, then?
