Truncated pyramid subwoofer (1 Viewer)

[Mike Robbins]

I know I saw someone who built a truncated pyramidal subwoofer here before. If someone or that person can post with links to his website or that thread, I sure would appreciate it.

Are you sure it was a pyramid?

I've seen two designs recently that were cubes set on end with the faceted edges? There were threads about these at Madisound and DIY Audio forums

I'm fairly certain. It was an impressively built box, and I'm a fan of the non-cube subwoofer.
