For some really testing bass, the sound wave scene in Hulk is a good start, although some may not want their sub stressed in such a way. :huh:Any ideas for good demo material? I'm guessing the best way to go is a good mix of stuff. Some heavy bass movies and some music. I think acoustic bass would probably be one of the best way of evaluating these for SQ. Wanting to make a dvd with around 30 minutes-1 hour so we have plenty of time to listen to each sub.
