I was curious so I grabbed one to potentially use with the Heil drivers. The actual crossover point is 850Hz with 12 dB slopes. They used 18dB slopes in the passive applications but I figure I could either switch up to a 24dB L/R or add a passive poles to get 18 dB slopes. It has a nice high-pass function and an adjustable Q bass boost at 30 Hz with a Max of 6dB boost so a Q of 2 That sure does sound familiar.
