Axiom Home Page Forums General Discussion Technical Questions Question on connections

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
