Precision Devices PD.1850/2 compression

Speaker Asylum

General speaker questions for audio and home theater.

I am planning to build large bass horns with JBL 2243. Since these are out of production I have started looking for alternate drivers with same parameters.

I found Precision Devices PD 1850/2, http://www.precision-devices.com/Product-Details/PD1850-2. This driver is a monster :-)

Letting Hornresp do the optimization for a 0,5 pi horn with lower cutoff at 20 hz using 3 drivers results in a compression about 5. This seems a bit high. Horn throat pressure is 8 k pascal at maximum SPL.

Does anyone know at what preassure cones break down?
