Marty, mine would tell your better half not to bother, if the statement came from me. It is probably exactly that, what Marakanetz meant with the cancellation of out of phase signals. Your wife and mine would probably agree, that we're mostly out of phase anyway. The only thing, all four of us might agree upon is, that horizontal biamping is generally more comfortable, with generally the same pleasing results, as compared to vertical biamping. Cheers,
