I have noticed dropouts with my sub for quite some time now but never like last night during a viewing of We Were Soldiers. The dropouts of the sub was constant and irritating. Enough that I am considering dropping the sub! I do know the sub was getting a signal since my bass shakers continued to respond. I have a SVS PC20-39, calibrated with video essentials, running at -5db setting from a RX-V1 Yamaha. I changed to -7db but the same dropouts still occurred. I was not at reference level... rather at around 10db below. The 20-39pc is a little over a year old,and has the improved driver mod. As I said, I have always had dropouts from this sub but just not as many as last night. Is it time for a trade in???
