I've just been given a PSW50 Sub to go with my RT15 + Polk centre & small rear system. I can't get my Nakamichi AV-10 amp to recognise the sub using an RCA lead to either L or R input ports. When I try parallel wiring the RT15's I get very low bass from the sub (have checked the wiring polarity - all fine). In this mode the amp shows 'error' when you switch subwoofer to 'yes'.
Another problem - the mag sheilding on the RT15's seems to have now failed - and I get blue and green corners on my CRT!
Is there a manual download for the PSW50?
