I just bought these from Velodyne: http://www.velodyne.com/velodyne/pro...V&sid=447f725b $172 with tax and free shipping. I just hooked up the front 3 to my H/K reciever. I know the connections are good as I swapped them out with my Pioneer towers and Athena center. My H/K AVR230 immediatly goes into protect. As you can see from the link I provided, these are 6 ohm speakers. It clearly says though that they are compatible with 8 ohm recievers. Can my H/K just not handle them?
