Part of it is my room. I have a null that's hard to deal with to begin with. It was harder dialing the Ultras in than my current speakers, but the same null is still there with them too. The Ultras were quite a bit bigger so that's partly what made them a little less flexible than my Sierras. Both are great sounding speakers tho. I was super happy with the Ultras and would probably still have them if I hadn't stumbled across a steal of a deal on some RAAL ribbon speakers.
