I need to think on this some more. The nature of bass waves is highly interdependent and I don't believe the direct wave from our little subwoofers dominates what we hear, Soundhound's system notwithstanding. The drivers are simply too small to support waves that are 20 to 30 ft in length without help.

I'm sure I don't have any crossover problems in my room and the position of the subs is fixed. Nonetheless, I'm going to run the tests that Bosso suggests and see what the charts look like.

Thanks for the answer on the delay settings in the 950.
