And what kind is it port,horn, or a hybrid.

I am just trying to understand how they work

or if possible could a get some kind of a horn design for either a single 8,10,12. For learning purposes

Other cornerhorn designs have folds that make a narrow throat within the cabinet, and a final flare that is formed by the rooms corner. The π cornerhorn design is very simple. The horn is deleoped solely from the room corner, and there are no folds within the cabinet. This provides a conical horn and provides directional eighth-space advantage. It is a simple design that works very well.

This design permits you to use a higher crossover than with a Klipsch-type folded corner horn, doesn't it? Thus, you are able to use a two-way system with full compression horn loading above the woofer? (Avoiding the need of the "Holy Grail" midrange.)

Performance from this cabinet is excellent, with a nice flat response curve. Really, you can use any box size between 0.4ft3
and 0.8ft3 tuned to 40Hz, and response remains nice and flat. If you get much above 0.8ft3, the system becomes underdamped and peaky. But you can employ an EBS alignment using cabinets between 1.0ft3 and 1.5ft3 tuned to 30Hz. This gives extended, deep response with a fairly shallow shelf of only 3dB reduction. That's a pretty good solution.

If your cabinet is much larger than that, it really should be sealed. There are many that prefer a sealed box, and if that is what you like, then a large box is acceptable. But f3 is way up there at around 100Hz, so I don't really like this approach. Then again, rolloff is slow and gradual, so it isn't like you are absent of bass or anything like that. Still, I'd run this speaker in a ported box between 0.4ft3 and 1.5ft3, tuned in one of the ways described above.

At any rate, once you've chosen a motor chamber size, then you can make a π cornerhorn based on those dimensions. I gerenally prefer motor chamber alignments that are critically damped to slightly overdamped for this configuration. EBS alignments are acceptable, as are other slightly peaked (underdamped) alignments, but as you might expect, they'll increase punch at the peaked frequency. This is sometimes pleasant, sometimes not. But the π cornerhorn configuration is generally pretty forgiving, so as long as your woofer/cabinet system is well formed and sounds good, then your cornerhorn will sound good too.
