I'm afraid I really don't know that; I've never heard an SVS sub in person. In my room the EP-350 kicks out enough bass to balance everything but is definitely not in the realm of overkill. I think that if you want to knock dishess off the walls and break windows, you'll need an SVS, otherwise just stick with the package (you'll get big discounts if you buy your whole line from Axiom). You may want to try to find someone who's heard both an SVS and an EP-350, though.

Another possibility is to go with two EP-175's. Some people prefer to have multiple smaller subs than one big one.
