I am not at home now, but I believe that I had the same problem when I switched out the speaker. In any case, I would like to look the possibility of a problem with the bi-wireable hookup. The speaker manual is not very clear about how the bi-wiring works. I'll check to make sure the jumper bar is in place. Unfortunately, I won't have a chance to try it out until I return home this weekend. I'll let you know how it goes.

Otherwise, could it be a 1050 setting?
