Ozzy,
Congratulations.
To be honest, I hate futzing with speakers. My approach is to just make a little move every few weeks. If negative…. Back immediately.
if I don’t force a slower approach, I end up in a frenzied dervish of activity, wanting to get it over with and concerned I will end up with the system sounding worse than when I started.
Ideally, you want to talk a couple friends into spending two or three afternoons moving them for you while you relax and listen… without having to get up. I’m not sure what you would have to do to bribe them. I would feel so guilty, I would never allow myself time to actually make good judgements.
So, congradulations, sounds like you got there.
