The trial period on the Legacy Signatures was truly my savior! I ended up purchasing a pair of Martin Logan ESL 13As and presto, they sound awesome! With a frequency response: 24–23,000 Hz ± 3db and two 10" powered woofer there is no problem with bass in the room now.
I had MLs in a similar room in the past with little treatments and they were very forgiving. I’m sure there’s room for improvement, but the way they are sounding right now, I’m in no hurry for treatments at this time. I’m just enjoying the music! I have an updated picture on my profile.
Thanks to all for your help and suggestions regarding my original post on this problem.
