RE: How many subs? and should I go from 5.1 to 7.1?

1. The in-room bass smoothness goes up with the number of bass sources as long as they are spread fairly far apart. This way each sub produces a unique peak-and-dip pattern at any given listening position, and the sum of two or more dissimilar peak-and-dip patterns is smoother than any one alone would have been. So in my opinon adding a second sub (preferably along one of the walls opposite that corner) will improve the in-room bass smoothness. Given that small rooms generally have worse bass problems than large ones, adding a second sub is arguably of greater benefit to a small room than to a large one. This seems counter-intuitive, but the reason for going with multiple subs is bass quality, not bass quantity.

I was speaking of the practicality, not the theory. Just how many people (seating positions) do we have in a *small* room? Anybody sitting near a wall is screwed, the bass/LFE lack of smoothness is the least of their audio problems. And the practicality of placing more sub(s) so somebody isn't sitting almost on top of one in the small room, which is worse for them than "lack of bass smoothness".

Sure, if you can work out the practicalities with regards to space/seating, another sub is theoretically better.

I always say (and feel free to disagree) that there is only ONE optimum listening location in a typical HT room. And that place is MINE. Nobody else has to know, how would they since the only paying customer is always in it. :)

  The original poster asked whether adding a second sub would smooth the bass, and that's what I was responding to.
  
  Did I miss something?

    Only the practical aspects of in a small room.
    It's a small *HT* room, with 5.1 speakers already, plus a display. Multiple people (presumably) sitting. Not a stereo music room. Different practicalities, different compromises.

      He has already determined that a second sub will fit in his room. From the original post:
      
      "The current sub is located near (but not in) one of the front corners. The other one could go anywhere along the back wall..."
