Hi all I need a hand with my Klipsch 2.1 Promedia speakers... I bought them somewhere in 2014, used for about half to a year, then kept for 2 years till now. When I brought it out from storage, the speakers are able to power up but has no sound at all. When I plugged those speakers into another sound system, there's sound... obviously the issue is with subwoofer... any idea how can i rectify this or do i need to send the subwoofer to repair center?
