Creating a system you love shouldn't be difficult. The Acoustic Frontiers blog is here to help.
In this region the response at the listening position in two channel listening spaces and home theaters is dominated by the off axis response of the speaker. On the face of it, this seems "crazy"...surely the direct sound dominates? In recording studios or other nearfield listening situations the direct sound does dominate, but as Harman research shows the frequency response at the listening position above the room’s transition frequency can be predicted from the anechoic measurements of the speaker by combining the data together as follows: 14% direct sound + 44% early reflected sound + 44% late reflected sound.
