I can see there are speaker companies out there that dont use wood. But the issue here is not just about the material its the shape. Magicos are RECTANGULAR BOXES. Even worse they deceptively try to make their speakers look round by adding curves but its not even close to a sphere. Its as if they know their speakers should be spheres but because they cant be bothered they just stick to boxes and hope audiophiles can be persuaded theyre just as good.
The Olson paper measures and describes the effects of speaker and baffle shape with respect to diffraction, that research doesn’t deal with resonances or internal wave/reflection behaviour per se (although those effects may influence the measured results)..
Nobody said it was dealing with internal resonances. Resonances will always be there regardless of shape and will need to be dealt with in some other way. The olson paper is correct and the speakers companies are wrong.
That poster described those aspects of the paper accurately, agreed with you that the research was informative and she suggested more research in that area would be interesting. That isn’t in any way contradicted by citing examples of near- or semi-sphrerical speakers.
Well in which case just admit that 99% of speakers out there are wrong because they arent spheres. You cant make a rectangular box behave like a sphere. Its one or the other. Make up your mind which is better and stop being ambivalent.
