Hey Earl, sure can do.
Do you prefer any format? Values separated by comma, space, tab or semicolon?

You can see why I don't consider the 511 a true 500Hz horn. 600-650, maybe. I see the same results on the normal 1" version.
We did not measure efficiency of the horns, other than relative. The T-350 looks to be about 4-5dB less sensitive than the 288/511E at the same drive voltage.

No acoustic measurements of the 416 drivers as the box isn't built yet. That is the least of our worries at the moment. I have enough measurements of mine to get us started.
