Tbg,
This is audiogon. Laws of physics are very often suspended here. Our favorite products do everything perfectly with no drawbacks or compromises to our favored designs. ;-)
For those with line arrays, this explanation is one of the simplest I have seen:
A good graphical explanation about lobing or "comb filtering" - which are the same thing. It shows snapshots at different frequencies but if you imagine how it will sound at a particular listening position across all frequencies then you will realize that you progressively get multiple nulls as you go higher in frequency.
