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.
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.
