Hey PA / Live Sound gurus:
I'm smitten by a pair of compact EV 15in 2 ways, but they come in 2 different coverage patterns: 90 x 50 and 60 x 60. At first thought I was inclined to go for the wider 90 degree horizontal coverage, but the sales guy was plugging the 60x60s because of phase cancellation issues with the 90s in a lot of rooms.
He felt for most small to medium rooms the 60s would sound better in front of the stage, with less off-axis dropouts. I'd always thought the dropouts were due to insufficient coverage angles rather than phase cancellation, but apparently no. He says the 60s pointed more or less straight out, with their audio "paths" crossing in the back of the room, would sound better than the 90s because those paths would cross closer to the stage and create more dropout / phase cancellation issues.
Does the 60 x 60 argument make sense? Educate me.
thx
