I believe that if you really like Home Theater and action movies, you want to get something that gives you pretty decent 20HZ performance.
There was a thread a Loooooooonnng time ago, maybe 2-3 years, where people were discussing the fact that there is definitely sub-20HZ content in movies, but there really isn't THAT much, so you could get by with something that gets down to 19-20Hz pretty well as long as you understood that you were missing something, but still getting like 95% of what was there.
Subs that only go to 23-25 are missing more. Subs that go to 16 are missing less.
So there's stuff there, but back then it felt like 20-ish was the threshhold for getting "most" of the low stuff. Maybe someone who has been doing waterfall frequency charts of recent movies can speak to whether or not this is still the case?
