While waiting for Ivans update a quick google search on the term 'speaker comb filtering' will provide a lifetime of reading enjoyment.

Would you have a more current link to this document, cos its no longer available online?

...With the same frequencies being produced from sources offset horizontally the aggregate horizontal dispersion will be an unpredictable mess of peaks and nulls.

Doesn't that almost describe this particular speaker even when used as intended?   :P

Arrogance is usually far worse than ignorance. But every once in awhile they swap places.

That happens with ANY loudspeaker(s) that have drivers arriving at the listeners ears at more than 1/4 wavelength apart in time.

That is why it is important to use a single source of sound, or if you use multiple cabinets, use cabinets that have large enough mouths so that they have real pattern control so the levels from the different cabinets are very different, so they don't interfere with each other.

Small horns-or narrow horns that are not LARGE, simple do NOT provide this needed pattern control

The OP wasn't actually talking specifically about VRX; he simply used that as the closest similarity to the design of speaker he wanted to build. Riley's comments, therefore, were directed specifically at the intended deployment that the OP was suggesting.

A bunch of BS & drama later, and several story changes, the OP got upset and left.
