I'm looking for a subwoofer to go with my M60 v3 towers. I'm thinking about the EP350, the Hsu VTF-1 or Hsu VTF-2 Mk-3.

I listen to about 95% classical and the sub is to bring out the bottom end, especially for pipe organ music.

Any suggestions or comments on the advantages of one sub over the others? I know the price and specs on paper, but am interested in hearing from anyone who's heard any of these subs in action, especially for pipe organ music.

Thanks.
