A few pictures of my B3N spheres.

Not much to say about them, just a few pics.

Made me wonder, has a bowling ball ever been used as a speaker enclosure? Would be a pain to hollow out, but dead as all get out...

Nice looking little spheres. Was about to say cube. But hey. As for the bowling ball... Would be interesting. One is to assume whatever it is made out of would be pretty hard to work with.

These are pretty close to bowling balls...

Nice work there. Presumably the idea is to reduce baffle step effects in a design like this? How is the sound?

Bowling balls are some kind of resin. I expect its extremely tough but perhaps a lathe would be capable of hollowing one out

What about getting a custom 'bowling ball' moulded -- only hollow?

Thanks. They're amazingly easy to make, and look good as well (and cheap!). I think the sound is great. Although the enclosure has a Q of about 1.4. I'm not using any BSC yet, just Zaphs notch filter. I'm crossing them at 120hz LR4. I havn't had distortion issues yet at moderate volumes.
