****?Doesn't matter so much for low frequencies but cubes are where you can get into trouble and that's only if you plan on going pretty high in frequency.
It wouldn't be worth the trouble really. Spheres benefit mid and high frequency drivers, not so much low frequency drivers. Although, structurally speaking, they are the best.At what frequency would the spherical benefits of an enclosure become audible?
...because I can make a sphere....
