I actually find Room Tunes rather effective, if tricky. But what isn’t? Certainly Tube Traps often take some experimentation to find the ideal locations and can actually hurt the sound if you’re not paying attention. I had good luck with Corner Tunes and Echo Tunes and the long narrow panels for room corners. As I said elsewhere the XLO Test CD is invaluable for getting room treatments as well as speakers precisely situated. There are too many variables to do it by ear. You could mess around for years.
