Installation:
Installation was as simple as plugging the speakers and control pod into their corresponding spots on the back of the subwoofer and then connecting the 1/8" input cable into my computer's sound card. There were absolutely no troubles encountered and it's easy enough that everybody can do it!

Testing:
I was impressed with the Expressionist ULTRA set right from the first song I played through them. The range was wide and the speakers seemed to have a nice bright high end to them. I ended up finding my comfort level with the trebel down a few notches and the bass in the upper one third region. With everything flat, I found the sub didn't come through at average listening levels and that the highs were a little too "crisp" for my liking. Everyone's taste will be different through.

I also threw on some action movie trailers and high-definition video demos, I like these best for testing speakers because of the wide range of sounds and thunderous low notes they contain. This is where I felt the Expressionist ULTRAs performed their strongest. The crisp high end was excellent in movies and made sound effects and speech really come to life. The sub woofer had just the right balance that it gave me the rumble I wanted, but wasn't too overpowering.
