I got a suspicion that we all collectively wasting our breath, but I hope I uncovered few things which were educating.
afterlife, I don't doubt that NAX-BAS-500 is a reasonably powerful sub, especially for HT. It has very little to now the lower end of extension, but it does nicely from 40 to 80 and there are a lot of content in that range two. My biggest gripe with that sub is would be simply a disaster for music. I know it's a lot to ask solid ht and music performance out of $300 sub, but it's not completely impossible.
