A modern spelling of Thought that losses the now silent letters.
The K in knife was also originally not silent, it could be spelled nife.
I do the short-cuts often.
What is that thinhg the lady built?

It also has a colloquial use to mean a person who has many sexual relationships. E.g. " Naomi Wu is a self-professed thot queen."
Have you heard those Tektons with the SB tweeter arrays?………I’m intrigued every time I see a new one pop up and end users really seem to dig em…….maybe they’ve figured out a focused point source for real?
I remain Skeptical
I over stated, I have little skepticism about Tekton tools.
They (Tekton speakers) publish no measurements and they are aggressive toward reviewers that do measure their products. The outlets that give them positive reviews are the ones that don't measure and rarely say anything negative about any product. I also find their marketing and philosophy cheesy.

There is a good chance that there is a terminology difference in our descriptions.
When viewed from basic acoustic principles and established terms an omnidirectional response is equal to all directions, in 4pi free space the DI will be 0dB when the response is truly omnidirectional. When the various curves are still diverging there is still some directivity and the response is not actually omnidirectional.
Where the darkest red colour in a normalized sonogram goes boom is where the box loses all directional control, just as there is the step above where the baffle loses control. These will vary with baffle width and box size and depth. The fact that the DI is not zero shows that the response is still not truly omnidirectional at that point.
You could call that point whatever you like, I'm not aware of any accepted term. What it technically is not is omnidirectional. The DI is often around 3dB at that point. There is certainly no significant directivity and to all intents and purposes the sound will be going everywhere. Semantics maybe but mixing up terms that have specific meanings creates confusion, and becomes the basis of accepted myths.
You may have seen in one of the Klippel graphics there is a visual showing where the different mode shapes become unreliable to describe the directivity. The monopole mode, n=0, starts to diverge at about 150Hz, in that graph. This coincides with where most closed boxes have a 0dB DI. Vented boxes are more complicated.
Don’t throw out the baby with the bath water. I’ve heard some DIY speakers that borrowed the tweeter array idea, but they used an array of Mark Audio full rangers just for the mid-range (14 per side if I remember correctly). Best mid-range I’ve ever heard from cone drivers ie as good as an ESL. Dave may be aware of them as ScottMoose was involved in their design.
