My SW12 died so now I'm looking for something new. My current setup is NHT ST4 towers, SB2s for surrounds and SC2 center driven off a Yamaha RX-V3800 (next item to be replaced). My budget is around $1000 for the sub but willing to go higher if it makes sense. From the reading I've done sounds like either the HSU VTF-15H or Rythmik FV15 would be a good option?? This is mainly just for movies and TV. Would it make more sense to get two subs? My room isn't that large but it’s kind of open. Any advice would be appreciated as I haven’t really looked at speakers in years.
