Will there be damage to the M60 is the binding post jumpers are not attached and the speakers are connected to either the speakers from a friend who didn't tell us there is a jumper to connect both binding sets so we just connected the top pair. Of course, the sound wasn't great (the lower frequencies weren't there. It sounded as if the lower 2 woofers weren't driven at all. Just curious to know if any damage could have been done.
Thanks
