Level in dB (left axis) and impedance in ohm (right axis), 10 Hz to 20 kHz. The line on each switch above shows how its curve is drawn.

Features

  • Advanced TeXtreme® cone for improved piston operation
  • Large optimized motor system with under-cut pole piece and dual shorting rings
  • Vented aerodynamic cast aluminum chassis for optimum strength and low compression.
  • Soft low damping rubber surround for optimum transient response
  • Linear symmetric suspension design for improved dynamic performance
  • Non-conducting fibre glass voice coil former for minimum damping
  • Long life silver lead wires attached 180° apart for improved stability
  • Vented pole piece for reduced compression
  • Low piston to chassis diameter ratio
  • Gasket and bolt hole protrusions for reduced coupling to speaker cabinet.

    SATORI WO24TX-8 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 SATORI WO24TX-8 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 Acoustics datasheet, so it is not a measurement and not an official SB Acoustics 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.
