I just listened to a friends Bose 201 system at length, 1st release I assume from pics I've seen. He said they were in the garage of a house he just purchased and the drivers were blown. He sourced the replacement woofer from a parts express special for $5.88 eacch and his brother gave him cone tweeters that had McIntosh stickers on the back. He said there was a coil and cap inside. There are foam corners that were gone but he is a physical therapist and he used some pads for forearm use??, blue in color but they look the part, guess... He has it hooked up to a Advent 300 receiver his dad gave him. OMG!!! what an incredibly musical system. Obviously not banging down the walls but it sounds phenomenal!! the room is probably 8' X 12', an alcove off the garage. He screwed 1 X 4" board into the plastic box and then screwed that to the interior plywood sheathing about 10" away from the corners 5' high so they clear a tool board. What gives??, the low end is how it should be albeit "smallish" but those cone tweeters are so detailed, delicate, and precise. Did we all miss something with the cones or maybe is it just physics and chance??
