Center channel Impedance.

[E-Stat]

I have no doubt about your knowledge of this type of speaker, you own them. But to say they will NOT have a dispersion interference pattern at some point is simply not true, especially when they are playing the same signal.

Who is it who made such a claim? What I did was observe that your sweeping statement (completely independent of the OP's question) that there is NO difference in horizontal dispersion between point source speakers and dipolar panel line sources is most certainly not a correct assertion.

Even if you are controlling both the horizontal and vertical dispersion of a speaker, multiples of them tightly spaced together playing the same signal will still have wave interference PERIOD.

You seem to be caught in a negative feedback loop. While your point has been restated, you have returned to post #11 - to which I responded in advance in post #10. Let's review the facts:

1. Optimum center channel speaker arrangement is uniquely found in the cinema environment employing vertical symmetry of the three front channels.
2. Most HT arrangements don't allow for what is known to be ideal.

Pick your own poison by determining which parameter you choose to optimize over another.
