It is a compression driver with an 8" cone.  If you want authority at 300Hz you will need diaphragm area.  The Fane Studio 8M that Romy and plenty of others use for 100Hz up to 1kHz is an 8" cone driver on a 4" throat with a closed back-chamber to make it into a compression driver, which effectively is the topology of the 2169H.
I respect others experience, but still not sure that I want to hear 8" diaphragm in 500+ range.And with 1st order crossover I'll have it.May be I'm wrong, but really...27gramm is too much. My 12" Supravox in 42Hz horn is 18g.And I also made it in closed back-chamber like compression driver.
