I owned a pair series IIs way back in the day, yes they were setup properly and I thought they sounded great. Sold them. I now have a pair of series VI that are in my garage facing backwards. It may sound crazy but they sound really good in a 1000 sq ft space that is all concrete and cement block. And no doesn't sound anything like the main rig. They don't image at all, but they fill that space with bone crushing volume if you desire. Which I do regularly......I don't get out much. \8-).
