hi all, i'm searching for a decent sub on a limited budget. I was considering the Paradigm PDR-10 or PS-1000. Richer Sounds told me that the PDR-10 has had a lot of problems with humming in standby mode (has anyone heard about or experienced this). The PS-1000 is bigger than i wanted to go. Richer Sounds suggested the Mordaunt Short MSW-20 (has anyone any views on this). Any other suggestions will be greatfully received.
