Why are there few spherical speakers?


We all know the best shape for speakers is spherical so why are there so few of them on the market? I have heard the excuse that spheres are hard to produce but that is not a good reason because even when you get to the price point of a Magico, they still choose to use the same old rectangular shaped box. 

Why do speaker companies think its ok to take us audiophiles for a ride by selling us inferior box shaped speaker designs?

Speakers are only one aspect of the sound.  Why did you buy a preamp and amp that is inferior?

Happy Listening.
Not precisely spherical but not successful as they sound impressive but ultimately a bit crap. https://www.whathifi.com/us/devialet/gold-phantom/review
And if there are so great, why arent all speakers spherical. If they were, engineering-wise, the best solution then most speakers would long be spheres and no one is in the busi was to not make their interpretation of the best sound. What peer-reviewed engineering papers can you produce that say spherical is best?

I did not know that. You are stating this as a fact. Provide some empirical evidence.

Thanks

P.S. Do you know guitarsam?
"Why are we not being catered to? " I’m not so sure the industry is ignoring the demands of the marketplace, as you seem to imply. Where do you see the unmet demand for spherical speakers? It’s a legitimate question to ask why the sphere is not more commonly employed, but you have a faulty assumption in the mix. Have you yourself ever communicated to a dealer or manufacturer a wish for spherical speakers? Probably not, right?
