yes it is possible but there is also high voltage inside there. a qualified bench tech type person could do it, but is it worth spending money? Not really...
Well, I don't really have much money (which is how I came into possession of this sub-woofer to begin with), so I just try to everything myself regardless.
Maybe somebody out there but I contacted Logitech and they discontinued selling them, even in pieces.
If there's a way some "qualified person" could do it, then I'll try to figure out what they'd do and just do it myself. All I need to know is how and with what tools.
