Quote:Weren't we talking about subwoofer placement? As in, whether placing subwoofers to improve the sound at multiple seats necessitates worsening the sound at the sweet spot?
As for level and distance settings, those are good for a single point in space. I dial those in as normal but am not anal about those settings because neither one of my ears will be precisely at that single point in space.
Quote:Things only appear magical if you believe they're not possible. But there are ways to lessen differences between multiple seats. Researches like Todd Welti have spend a career figuring out ways to do just that in the subwoofer range, taking into account multiple rows of seating.
By comparison, my 3-seat couch (single row, single height) is small beans. By minimizing how drastically the sound falls off outside the sweet spot, I don't have to insist that listeners limit themselves to the sweet spot.
Quote:But if the majority of the problems in the subwoofer range are due to room modes (as opposed to, say, speaker boundry interference), then it makes sense to place subs at locations that lessen the effects of those modes. Since modal problems span a dimension, reducing the effects will improve the sound across the dimension (e.g., width)
So, even if you are reducing the effects of the modes solely to improve the sound at the main listening position, you can't prevent it from benefiting the other seats (as opposed to the notion that an improvement at the MLP will necessarily make things worse elsewhere and vice-versa).
Long time AVS poster Markus has a good example of improving the frequency response at the main listening position AND improving seat-to-seat consistency at the same time.
