Axis Settings

Several of us have expressed our inability to detect changes using different Axis settings. How much is the tweeter "moved" up and down with each increment? Is the ability to hear changes dependent on distance from the loudspeaker to the listening position? Is the difference extremely subtle or should it be readily apparent? Should the entire soundstage sound as if it were moved up and down? Is there something special we should listen for to determine whether a change in Axis is beneficial or detrimental? Is the Axis setting operational for horizontal center speakers? Should the Axis be set the same across all speakers? For those of us with horizontal central speakers whose tweeter height is above or below the tweeter height of the left/right speakers, is it possible to adjust the Axis setting of the center channel speaker only to "move" the tweeter up and down so that the height all the tweeters appears to be the same? Do you have any tips for us?

Trifield Width Settings

Several of us have expressed our inability to detect changes, or only detect very subtle changes, using different Width settings in Trified. Many of us remember having heard readily discernible changes in the past. We raised this issue in the past and you advised us that there was no change in the code which would lead to this result, and said that you would schedule a listening test as time permitted. Have you had an opportunity to do a listening test to confirm that the Width setting is working as it should, and if so, what were your results? Do you have any thoughts as to why we may be experiencing this issue? Is the subtlety or magnitude of the effect of the Width settings affected by the distance between the speakers and/or between the speakers and the listening position, and if so, how? Do you have any tips for us?

Trifield Depth Settings

Several of us have noticed that with every incremental change in the Depth setting in Trifield the sound from the center speaker appears to be in-phase, then out-of-phase, then in-phase, then out-of-phase. Is this normal behavior?

Instructional Materials for Setting Up Various Surround Sound Music Mode Settings

Do you have any instructional materials on how to optimally set up the various music surround sound mode settings other than that which is set forth in the product manuals. For example, do you have any training materials for dealers on the subject which you would be willing to share with us?

Thank you.
