I don't think TAM has been clear on how he feels about his subs.

About time alignment...my impression is that XT32 does a great job. I read that so many people believe their autocal gets the sub distance wrong. The sub distance shown takes into account all delays; it's not just the physical distance to the sub. What I don't understand however is if something like xt32 corrects for frequency-dependent group delay or applies some average.
