Photos of both kinds of speakers are shown in the document in my last post. It also shows you how they should be setup in the room. Perhaps I can help you decide which model would be better for you.

Do you have corners that would be suitable for constant directivity cornerhorns? If so, I'd suggest going with the seven π cornerhorns. They have some distinct advantages that no other configuration can touch - namely constant directivity across the full audio bandwidth and freedom from self-interference from boundary reflections. Those are significant advantages.

The problem is, of course, that not every room has the right layout for constant directivity cornerhorns. In fact, I'd say probably most rooms don't. In that case, go with the matched-directivity two-ways (four π) and use flanking subs. That will give you a lot of advantages, and with proper setup, you can get them to be almost as good.
