I figure I will have to maintain a 250-300 to 1.6+ Hz xover. I just was playing with the Alpha 6A as I wanted to build a nice mid horn for fun, but now I want to see if I can blend it into a suitible working speaker. Can I have plans for the six then to proceed in that direction with the delta 12lf. I figure the 2002 driver is the best tweeter to integrate into this per your plans. Love to see wood horn plans if available of bringing this to life as well. Thanks, Larry
