If I were to get a 500, for example, is there any advantage to replacing the current sub (same position) with a 500 if I'm currently satisfied with the volume of bass? Again, excepting that the new sub will go deeper.....

I'd like to think that I could get two 400s or 500s to help even things out, but that's an awful lot of coin and a helluva lot of sub potential for such a tiny room....

Any thoughts?


Let's set aside the fact that square rooms result in more difficult acoustical problems than rectangular rooms. For starters I would always recommend placing your existing sub as close to the listening position as possible to minimize room influences.

Moving up to a 400 or 500 from an old 350 is a huge stepup in performance and sound quality. Its not just about more extension. The 500 will give you much more headroom for sure which is always a good thing. However if you want or need the sub to be heard but not seen a 400 in that room would work well. And two would be better, especially in a square room. I'd suggest the 400 if budget and size are issues, though the improved 350v3 would also be a reasonable alternative.
