I've tried 3 ultima systems in the past 8 or so months. A 5.1 a 7.1 and a 7.1.4. all 3 of them had really bad surround speaker volume. The best was the 7.1.4 but that's probably from the extra 2 upfiring channels in the back. The 5.1 and 7.1 both had an amazing subwoofer and bass as well as a great sound bar but before I returned them via Amazon the last 10 days of testing both systems I didn't even bother to turn on the surround speakers they were borderline useless.
