@mlsstl good question. First of all, when I took out the rear speaker binding posts, I noticed the wires are connected with WIRE NUTS. Duntech would NEVER do that so the xover's have clearly been messed with. These are over 30 years old so it's not surprising they might have been tampered with and I'd like to know what was done. It's impossible to track down the original owner so I just want an expert to look and make sure things look ok and something wasn't totally jacked up.
They sound great as is but I wonder if I could be getting more out of them. Again, seeing wires with wire nuts is a huge red flag that an incompetent person was medling around in there.
