I'm wondering if anyone has measured this driver and might have these files?
CLIO measurements drop right in and work perfectly in Xsim.
But I don't have these measurements for the 904 driver.
Nor do I have a CLIO system. 🙂
Thanks
Ron

Good catch! It would appear that DATS exports the data based on the upper frequency set for their tzz file/session... which defaults to 5khz, so ignore the previous HF data posted. The LF data appears to be the same regardless.
Edit button has disappeared so I will repost the HF data.
