hi.I want to build a sphere or egg style speaker box for my nokia 4ohm 18cm 100watts speakers.they are about 90db and high detailed german speakers.I wanna ask that how important is an egg or spherical enclosure? which is better for me?I will use it with dome tweeter.Thank you

To make the most of such a cabinet you would need to look inte the blending of the tweeter front plate with the surface of the spherical "box", or you could get lots of diffractions there. Best might be to use some sort of waveguide, that bends backwards until it blends in seamlessly with the sphere.

Either should be great, but difficult to do well. How do you plan on making it?

If you're going to 'glass it a nice combo would be spherical outside with an egg shaped inner cavity.

egg, instead of 1 huge standing wave inside, it is more spread out.

Or spherical with egg interior (as dheming said)

What type of westra tweeter are you planning to use?

Sphere is fine if it's small relative to the driver and thus any standing waves would be broken up by the magnet structure.

Egg is eggsellent.
