Thanks Jim,

I did do some experimenting with positioning and room acoustics with no real
improvement. As individual speakers the IPL units sound fine...just no
proper imaging as a pair. Somebody emailed me suggesting that the ribbon
tweeters used could be the problem....does this make sense? Could they have
a narrow or uneven radiation pattern?

If an MF or HF driver were wired incorrectly could this explain the lack of
image?

My fully assembled Behringer monitors cost less than half of the IPL driver
kits (enclosures not included) and yet sound so much better...must be a
reason...
