Overview

The Whirlwind Cab Driver is a purpose-built speaker and loudspeaker component tester designed for audio professionals who need fast, reliable diagnostics in the field or the workshop. It consolidates several common testing functions into a single handheld device: a pink noise generator for exercising drivers and identifying mechanical faults, a DC voltage source for polarity verification, and an LED-based impedance indicator that reads 4, 8, or 16 ohms. With outputs spanning Speakon NL8, Speakon NL4, 1/4" TS, banana jack, and XLR line-level, it connects to virtually any speaker cabinet or component without adapters.

In practice, the Cab Driver streamlines a process that would otherwise require a multimeter, a noise source, and a handful of adapter cables. Audio techs can quickly cycle through cabinets before a show to confirm every driver is functioning, check polarity across multi-way systems, and verify impedance to ensure amplifier loads are correct. Its straightforward operation requires no training beyond basic speaker knowledge, making it a practical addition to any audio toolkit focused on live sound, installation, or repair work.

Pros & Cons

👍 Pros

  • Supports five different output connector types, eliminating the need for adapters during testing
  • Built-in pink noise generator allows quick identification of blown drivers and cabinet rattles
  • LED impedance indicator gives instant 4/8/16 ohm readings without a separate multimeter
  • DC polarity test makes it easy to verify correct wiring across multi-driver cabinets

👎 Cons

  • LED impedance indication is limited to 4, 8, and 16 ohm ranges, with no continuous reading for non-standard loads
  • Does not measure frequency response or provide detailed diagnostic data beyond basic pass/fail tests
  • No built-in speaker for audible confirmation when testing in noisy environments
  • Limited feature set given the price point compared to a basic multimeter and noise generator combination

Frequently Asked Questions

It features Speakon NL8, Speakon NL4, 1/4" TS, banana jack, and XLR line-level outputs, covering virtually all common speaker connection formats.
It applies a small DC current and uses an LED indicator system to display whether the connected driver reads approximately 4, 8, or 16 ohms.
Yes, by applying a 5V DC current and observing cone movement, you can verify whether drivers are wired in correct polarity relative to each other.
It produces pink noise, which excites all frequencies evenly by perceived loudness, making it effective for identifying rattles, blown drivers, and crossover problems.
The Cab Driver is a self-contained, battery-operated unit with its own built-in signal generator—no external amplifier is needed for testing.
