I must admit I don't know what the limitations are in the distance settings in the pre/pro calibration software.
Believe me when I say you have to have your gain structure spot on when working with super efficient horns (112db/w/m). Any background noise will be so obvious. Heck, just finding amps that were suitable was an ordeal. I think +4dbu pre/pro is the way to go, but the crossover I'm using has a -10/+4 dbu switch on the input, so it work just fine with a -10dbu pre/pro. But using the right tool for the job will give me more options on active crossovers.

With Audyssey (Denon, Marantz, Onkyo, NAD) the max distance is roughly 50' using the the stock Audyssey mic and 1 additional 25' connector while this distance can extend beyond 120' if using the Audyssey Pro kit mic.
That sounds encouraging, thanks for posting!! I haven't followed the pre/pro market in a long time. Are you saying that as long as I use a pre/pro with audssey +pro mike kit, then the speaker/sub distance can be set at high as 120'. Or are you saying that 120' is the max distance between the mic and the pre/pro?
