Hello, I've had this heavy speaker in my attic for 10 years. it was left by a former b/friend who told me never to throw it out as it was worth s/thing. That was 8 years ago: I'm moving & it's too big and heavy for me to look after. best method of disposal? If I can pick up a few $ in lieu of unpaid rent, great! otherwise, the best environmentally sound method of disposal? please help! Katharine
