I'm interested in your design. First, I've seen many OB designs with a wing or two on the tweeter/midrange array. Wing on the inside, wing on the outside, wings on both sides. I'd like to learn more about this type of design, can you point me to the resources you used? Next, on the OB subs, are those basically Danny Richie type servo subs? They look awesome! How much more output do you get over the two-driver-per-side version?
