Three Pi subs work great with constant-directivity cornerhorns. Place 'em in Geddes or Welti configuration and you're good to go.
The 12Pi hornsubs is also suitable. It's awesome - but it's big.
When used indoors, I personally would rather have a few three Pi subs in a multisub configuration than one large hornsub. I love hornsubs, but indoors, modal smoothing important.
