GPA it is. Nice folks. They responded to my email right away, and picked up the phone on the third ring.

I ordered the 902's yesterday. The curves which they emailed me show a marked difference in the upper range compared with 806a's on the the 811 horns. At 15kH, the 806a's look to be around 22dB down relative to 1.5kH. The 902 look to be 7dB down.

A bit over $400 for the pair. I'll be selling the 806a's to reduce the final cost. BTW, they manufacture 802's for a bit more. I wanted the tangerine phase plug, so I went with the 902's.

I'll be reporting back in a week or so.

thanks all.
