My First Post! Im looking to add a quality sub in a decent price range to my home audio system. I've looked at both the HSU VTF-2 MK4 and Outlaw Audio Ultra-X12. Any other options in this price range would be great. I listen to a good bit of music along with your typical action movies. My system consists of 2 Definitive Technology BP7006 towers in the front, 2 Mirage OmniSat V2 Satellite Bookshelf rear speakers, and a klipsch reference r-25c center channel. The towers just don't give me the bass I'm looking for. Help! I need to stay south of $700 please.
