Listener - Why would you go with HSU or SVS instead of the EP500?
When watching movies I want the sub to have a big impact. While the sub can certainly deliver I have to run it a bit hot for it to do so and even then I feel like it is a bit lacking. I have heard some of HSU and SVS offerings and both were able to deliver the what i felt was the same performance for less money. I am happy with the ep500 but if I was to spend that much money again I would add a few hundred bucks and go for the svs pb-13u... I just checked and it looks like svs recently released a better more expensive version so it's more like 600 more than the ep500 now.
