Hard to ever put wings on it if it's lying on it's side.....

We had a great time last night, A.A. is always a great host and everyone had a blast. We did have some trouble concentrating on the audio, as Olympic Beach Volleyball was on the TV (sound off). :cool
I think we came up with a pretty good crossover by measurement and by ear. It was nice to have some trained listeners there to verify the sound of things. The crossover turned out to be 3rd order electrical with the horn reversed (IIRC). Acoustically the crossover point is circa 770Hz, but I don't remember the electrical points. It's what sounded best.
I'll get some measurement graphs and other info up ASAP - tonight I hope.

EDIT: Oh yeah, the traces you see above are impedance plots for the dual woofers and the horn+driver.
