Don't want to derail things, but we got rid of our wedges for hotspots before I came on board, and I sob softly every time I have to do a bigger concert. How do these, and other low-profile / small footprint, monitors sound off-axis?
What do you mean by "off axis" ?
Well-designed full-range speakers should sound fine when listened to off axis but
within the coverage limits of the speaker. The loudspeakers I have recommended here do the job quite well.
Hotspots, defined as a very small spot monitor with dual full-range cone drivers driven with the same signal, are fairly well-known for lousy (ragged) response that changes significantly across the coverage area. They cannot help but behave badly due to the inherent combfiltering from the 2 drivers.
