More testing with Tool's Anema and 10,000 Days (lots of lows and chest pounding bass). U-571, Blackhawk Down Blu-ray and Pirates 1 Blu-ray.
No contest, the Energy S10.3 definately digs deeper and I was able to discover something - I've had the phase wrong the whole time. In my setup -180 degrees works best. I've had the phase at 0 the whole time. Suddenly, the floors started to shake (not as extreme as the 5000R) but a marked improvement.
Yea, the 5000R is definately going back. I'd stick with the S10 for the time being.
Thanks for all the posts, advice and help from the numerous members here. This is why I love coming here.
