I have aquired one 2205A. It has never been used.

I know It can be used in 4530 horns. What about using it in a Hartsfield? I cannot find any information on thiele-small parameters of the 150-4C to compare it to. The cone is not the steep angle of the 150-4C or the e145, will it handle compression well?

I could also put it in a simple front loaded horn, like Volotreters.

Or of course sell it. Does anyone know if these are sought after at all?

Any suggestions would be welcome.
