I'm using the Shiva (downfiring) for these enclosures. Since they are very heavy (~90lbs), I'll have to special order some heavy duty stainless steel spikes for the feet.
BTW, these subs are "two of a kind", (I own a pair and Chris, the builder, own the other pair). Chris won't be building these anymore due to the amount of work involved in constructing, veneering, and finishing 26 sides with 12 coats of finish.
