I run all active. 2-FBT Maxx4a tops, 2-FBT Maxx9sa subs, and 5-FBT Maxx2a for monitors. And yes, you need to check the EQ's before every job because they do get moved in transport. I have resisted the power/xlr cables because of the cost, but I may be weakening. One downside to those cables is with the AC running inside it, I would hate for someone to put a high heel or something through the cable. The only problem in 5 years was one of the monitor amps went, but FBT promptly repaired it (reasonably priced). A couple of the pots are starting to get noisy, so I will have to address that soon. The system has a great sound and is pretty lightweight.
