Midrange: sealed dipole vs OB mounting?

[pieter t]

The speakers only become cardioid with rising frequency if you build them that way, I wish to build a pair with the same off-axis response and dipole pattern and on all frequencies

Good luck ; let us know when you have succeeded

Shame though that smaller tweeters aren't made that have perfect off-axis response all the way up to 15-20 khz To compensate the current plan is to have a ring of four cone tweeters on each side of the baffle, kinda like my current speaker but doubled to become dipole.

20mm tweeters behaving like pure pistons should reach 17 khz omnidirectional in theory, but other things like baffle diffraction have their influence.
A ring of four tweeters will only complicate things, not improve IMO.

Ring of tweeters works well enough on my current speakers so should work well enough on a dipole, at least probably well enough for me to try it
