dipole sub H-Frame, phase or opposite phase ?

Come to think of it, what would happen the other way around? It would become a quadropole, right? I'm not saying it would be good, I just wonder what would happen with the directivity and frequency response.

Simply a non-starter, given the module has to be rolled
off to supress the H frame frame resonances, so at lower
effective frequencies the two drivers would simply cancel.

Yes, it's probably a bad idea, I was just thinking that whatever little that comes out of it could be even more directed than from the dipole.

I think I heard of the opposite once, ie a quadropole microphone. It would be something they used in helicopters to supress ambient noise. Ah, well...
