. . . I didn't know you were running a pair of VP180s together, is there much more of an advantage using that configuration over a single VP180? How far apart are the top and bottom 180s?
My screen is 74" high so they are about 76" apart, not more. Yes, certainly there are advantages: - The dialogue is locked in the center of the screen. - The sound is seamless with the main left and right speakers having their tweeters also at the middle of the screen. - Because of the eye-brain role/relation when you see an action at the top or the bottom of the screen the sound seems to follow it perfectly. - All the benefits of having twice as much transducers/drivers to do the work.
I recently move all my speakers to the v3 models, added a pair of heights and a second A1400-8. Each A1400-8 is powering one side plus one center speaker - 5 Axiom speakers each.
