    Beta. These FRD and ZMA files are made by Artisan Acoustics from the curves printed in SB's datasheets. They are not measurements and not official SB Acoustics or SB Audience files. Use them at your own risk, and check the conditions printed on each datasheet.

    The marketing box is optional: you get the files either way. We never sell your details. Privacy & PDPA notice.

    ROSSO-8CX250 FAQ

    What are FRD and ZMA files?

    An FRD file holds a driver's frequency response and a ZMA file its impedance, the two curves a crossover simulator needs. Plain text, one point per line.

    Which software can open the ROSSO-8CX250 files?

    VituixCAD, XSim and REW, and most other crossover tools that read plain text.

    How was this data made?

    It was digitised by Artisan Acoustics from the response and impedance graphs in the SB Audience datasheet, so it is not a measurement and not an official SB Audience file. Each curve is checked against its graph. The datasheet it came from and the conditions printed on it are in the ABOUT.txt note and in the header of each file inside the zip. Use the files at your own risk.

    Why is the phase column zero?

    The datasheets print level and impedance but not phase. If your simulator needs phase, derive minimum phase there.
