        I used this driver to replace my damaged old one. I measured TS parameters before installing it into my enclosure. The TS parameters were not acc. to driver spec. yet (e.g. Fs was not 32 Hz as defined, but was 47 Hz). It is OK because driver was not burned in. It will need time. It is important to take it into consideration if you are building a crossover from the meaured not burned in driver.

        For my old Autovector speakers, I have replaced all mid-woofers with this unit - SB Acoustics SB17NRXC35-8 Perfect - highly recommendable.
