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?
