2235H Measured Speaker Performance - Anyone?

[Loren42]

Does anyone have the actual measured data set for a 2235H collected from something like a WT3 Woofer Tester?

I am looking for something I can import into Bass Box Pro.

I already have the T/S parameters, but I really wanted the complete data for the driver if someone has already captured it so I can correctly model this driver.

Thanks in advance,

Loren

This is a WT2 test of an AlNiCo 2205 reconed as a 2235 by OCS. Note that the BL is a little low (should be >20). The woofers were subsequently remagnetized and the BL went up to 22-23.
