The lowest F note on a standard 90 key piano, some of the munsic I listen to has the guitar tuned very low - almost an octave below a standard bass tuning, two octaves below standard guitar - the SVS subs have the capacity to push frequencies that low, most standard entry level subs don't hit that low.
Anyway, i appreciate the information. I am stuck in a hard place - needing a new set of speakers for almost 4 months now - and not knowing enough about things to make what feels like an informed decision. I run vinyl 95% of the time through my speakers, not much of a movie geek. My room is relatively small though and now am having second thoughts about buying tower speakers at all. Part of me wants to have patience to learn, and so tell, the differences between set ups, but I have 400 vinyl here that I want to play along the way
