If the driver taps into the horn at the very beginning it is a standard horn. If it taps in anywhere else along the side it is an offset horn, as the driver is offset from the true throat.

The HR help file explains how to input a BLH pretty well. Where exactly do you fall of the wagon, so to speak?

This is a small update.

I fixed the driver nominal size non-sorting error.
Added more of the Leach math to the right of the main inputs.
I also added some minor extra calculators, and a new driver data base parameter.

Same file with the protection back on, for those with twitchy fingers.

I was JUST sitting down with Marshall's book and his paper from 1979 to do a spreadsheet and here I find one far, far more detailed than what I had in mind!

Thanks so much for the good work. Saved me a lot of hackin...

Greg Richter, your welcome.

I have been getting some questions about the AE drivers, and why there is no dimensional info on them.

It's because the info is a pain to get too, as it is not listed with the driver parameters themselves. I when back and added in the easy to find models info. I'll post a picture here, and add a zip file. You can either copy paste from the zip, or manually input them from the pic.

If anyone has the remaining missing parameters please feel free to post them here.
