Martin Logan EDL


I have an opportunity to purchase a pair of Martin Logan EDL speakers and  Martin Logan subwoofer. The are fom 2009, but have not been used in past 5 years. When I plugged them in, one has a loud hum. Sounds to be coming from the bix with the woofer. Any ideas what would cause this, and if it can be fixed?

Thanks everyone. I was able to contact Martin Logan support. Could be a $100 fix or replace the speaker!
