My experience has been a combination of validation and learning. The Rythmik F12SE PEQ has been magically supportive of my Maggie 1.7s; however, my integrated Cronus Magnum III has been challenging, because my Maggies can't keep up and need to be crossed over at 80hz, 24db/octave high pass
So, I embarked on a passive crossover journey that resulted in a complicated story, resulting in me looking for a separate preamp, amp, and crossover. I'm hopeful my journey comes to an end or something close to it soon, because the system sounds so good and is only getting better.
