I have been playing around with the large/small settings, crossover settings, and sub phase adj,... been thinking about a disk (Audio video essentials, Avia, S&V HT tune up etc) and learning a little more about speaker set up. I do have a RS spl meter. I have also considered an RBH SA400 for the bottom of the 1266's, dunno,.... have to think about it some more ;-)
