Attachment 59268
Hi Rob:
If you look at the response family just above 1k, you'll see that the dispersion rapidly increases with falling frequency, and that there's a peak and a dip in the off-axis response family below 1khz, a telltale sign of a poorly terminated horn. With a proper termination on the horn, it'd have a more consistent off axis pattern, rather than as-shown, which has a power response peak at about 900 Hz. The horn is clearly not controlling pattern to 750hz in the horizontal, hence my gripe. It's not as bad as some other horns but given the cost of these systems and the quality of them in other respects, I hate to see such an easy fix being left out.
Best,
J
