In this post the User clams that the Compression driver Atlas PD5V is a derivative of the WE555, which was good down to 100 Hz

There was also mention of an AES paper on how to create a phase plug for a cone driver.

Based on Romy's ideas on a mid-bass horn, This might cover down to 200 / 300 hz to transition to a Tapped horn.

If I ever have my DCX break and need another XO, these tools look like they make miniDSP a real choice.
