Visual Identification Notes

  • Distinct motor/radiator layout differs visually from conventional cone subwoofers.
  • Archive photos should include motor exposure orientation and enclosure integration details.
  • Document installation angle and enclosure geometry for repeatable system tuning.

Known Issues

  • Poor integration with the wrong crossover settings can cause localization and weak blend.
  • Mounting and enclosure execution has major impact on performance and reliability.

Recommended Service Actions

  • Use active crossovers only and keep crossover points at or below 60Hz.
  • Confirm enclosure volume after accounting for Cyclone's own displacement.
  • Validate amplifier load compatibility with the 8-ohm nominal impedance target.

        Historical Notes

        • Cyclone Rotational Driver Concept

          Archived Cyclone documentation describes a rotational moving-magnet system and specifies system setup constraints such as low crossover points, active filtering, enclosure sizing, and the published 11Hz-60Hz operating range.

        Source-Backed Verification

        • Cyclone published archived FAQ specifications

          Imported - Needs Primary Verification
          • Cyclone spec table lists 11Hz to 60Hz response, 8-ohm nominal impedance, and 300 WRMS continuous handling.
          • The same table lists <1.5dB power compression at full power for 15 minutes and 90dB 1W/1M sensitivity.
          • Installation notes recommend active crossovers only, at least 18dB/oct slope, and crossover points below 60Hz.
