nonsense. You cant patent a shape. Why hasn’t anybody patented the rectangular box?
You may be able to patent an implementation of a shape. Apple irritated the always irritable interwebs by protecting their rectangle with rounded corners, I can’t recall how/if that ended.
The research shows it is the perfect shape. Speakers are there to reproduce what you play through them. They are not instruments. High end speaker companies know this.
I think Cabasse speakers are fabulous btw. I wouldn’t be surprised if certain elements of their implementation were patented, but haven’t checked. I agree spherical or semi-spherical shapes are wonderful and I’d like to see more of them.
Gallo made both entirely spherical speakers and used spherical housings in complex speakers, like their discontinued Reference models. I think he sold the company (not sure) but you could buy their Strada models recently (they being two midrange spheres and a curved tweeter).
There have been others that I can’t recall immediately.
We also have the egg-like Devialet.
And there are complex curvilinear shapes, B&W’s shell-inspired Nautilus, and Laurence Dickie’s later work as Vivid Audio.
And we have numerous simple or complex curved planes on numerous models. Previous generation Audio Physic had curved sides or backs (the current reference models are tilted rectangular prisms but don’t sound worse). Magico still do (and those giant Magicos are complex curves). Focal Utopia series generally don’t have any flat elements. Nor do certain Genelec series. KEF Muon. And so on.
B&W had one but we are not talking about subwoofers we are talking about regular speakers
Why not? Boxes may be the common/utilitarian/cheap box of choice, but variations exist as attempts to improve sonics and aesthetics. B&O make a complex polygon that approximates a sphere. High-end REL models are curved like grand pianos. Gallo made a cylindrical tube. Tune Audio make a lavish vertical horn. Genelecs SAM series are spiral sections. Avantgarde Audio make those fabulous-looking stacking spiral horns. And so on.
