I've only got experience with 2 subs, one of which you asked about. I demo'd a velodyne DLS-4000R (12"er) for a couple weeks and found it to be boomier than I thought a good sub should be. Based on input from the great and knowledgable guys on this board I looked and HSU and SVS. I decided to purchase the 10" SVS (PB10-ISD). It is much tighter than the velo and has great SPL's and oomph for my relatively small room (11x16x7). I'm sure HSU's are equally good.

There has certainly been a lot of good comments about the relatively new Axiom EP500, but I think a lot of it is from looking at the great spec.s and freq. plot. Does anyone know of any (or many) direct comparisons with other subs (notably the SVS or HSU's)?

What is the size of your room?
