Owl/Gonk - I started thinking about the CC response of 120 and checked their website and the CC actually goes down to 60hz. The 120 was for their rear CC...my mistake. I should have figured that out when I started typing last night - sorry for the misinformation. I assume then that with fronts that go to 50 and the CC at 60 I could set the crossover at 60 or 80. Will use 80 since the rears only go down to about 80. Thanks again for the help, you guys have been great.
