RT1000 amp problem

Hi all. I have an RT1000 (black drivers) that has a loud as all heck buzz/hum. The interesting thing with it is that the hum/buzz only hits when there is audio initially piped to the speaker (no lfe/sub input plugged in). So if the speaker is just plugged in, no problem. When audio starts give it about 3 seconds and the a floor shaking hmmmmmmmmm/bzzzz! The only way to stop it is to unplug the speaker. Is this a fix any mortal can handle? I don't know about caps/etc., but any given tutorial I can generally follow with ease. I know my RT55's and a sub would be a better bet, but after not playing them for many years and recently giving them a listen they both sound like their crossovers are shot. So the RT1000s first and then we'll move on to the 55's then the 12C.

TIA.

    Crossovers normally just don't go bad. Why do you think they are bad in the 55s?

    Thanks for responding @rooftop59 .They don't sound right, generally muffled. They were college speakers and then did surround duty, but have sat in my basement unused for 10 years+-. I recently broke them out because I was bored with the B&W CM1 that I had and they sounded uneven/muffled. There was distinction in sound between them. So I put them back on the shelf for another day (I see there are mods to improve them). and moved over the the RT1000, which have the amp problem, which I'd like to focus on now (if not a lot of $$).
