The EV S1202 has an OEM version of the EVM12L for a woofer, a DH1202 compression driver on a 90 X 40 CD horn.

The EVM12L has a 60hz Fs and response droops below 200hz when used as a direct radiator, works fine for mid-bass. It is a good horn driver.

A DH1202 was a 1-1/4" phenolic HF driver with a minimum recommended crossover point of 1500hz, useable to 15Khz on top.

The horn cut-off is 800hz, minimum crossover for good directivity is 1.6Khz

The later S1202ER has the titanium DH2010, an OEM version of the DH3, useable to 24Khz.

This diaphragm will retrofit into the DH1012 and if yours have ever been changed you may need to check and see what you have.
