I was wondering what your guys' thoughts would be. I'm planning on buying a new sub in the next month or so, and have already decided to go SVS. It's hard to know which route to take though, with multiple lines of powered and passive subs. Is there a performance benefit of going passive with a separate amp, or should I stick with something integrated? Here's my current setup: Sony DA3ES Receiver Axiom M50 Fronts Axiom VP150 Center Axiom M3 Rears Engergy e:XL S8 Sub (8") I was planning on going with a 39" SVS, since it's mid-range. The current room it's going in will be about 15x20, but that won't be it's final resting place. Any thoughts? Or other threads that have discussed a similar situation?
