Hello Everyone, I would like to say that available now is a new version from woodhorn.com. 
This is a 12" horn as opposed to the Classic Horn that is 17".
The cut off for this horn is 1000hz. It's great if your cabinet design calls for something a little smaller. This horn also has the X-Flare option which is a tractory curve at the edges of the mouth. Thanks for looking, Bill Martinelli

I don't even know what I will build to go with them yet, but I really want a pair of these. Are they about the same price as the 17" horns? As always, really nice work Bill. Thomas

The original 12" Omega specs show a sharp dip @ 1.5k, the Delta a sharp peak @ 2k, and the Alpha has rising response plus a high QTS that makes it hard to put in a compact box. [Further, the specs seem to change daily.] I don't see where in your crossover document you really show how much the network really handles these issues. In an all Eminence solution using these new horns, where a compact solution would be desired with an exposed horn, what Eminence motor is going to give the smoothest transition through the crossover?

You're right that Alpha 12's and 15's need really big cabinets, such as is the case with the Thermionic Series speakers. And the Delta 15 in the Theater four and seven π speakers has a rise in response around 2kHz, but it's crossed over at 1.6kHz and there's a Zobel to smooth response there. The Theater three and six π's Delta 12LF is a nice, inexpensive motor that can be used in a small box. You might also want to consider the Stage Series four or seven π, containing an Omega 15. Generally speaking, better motors cost more money so you can expect performance improvements from the more expensive offerings. In any event, remember that all drivers have response aberrations; If they're under 6dB then the response meets the criteria of being "flat +/-3dB."
