- Sensitivity measured at 1W/1m.
- Power handling (RMS) is a 2-hour pink noise test from the recommended crossover frequency to 20 kHz. Program power is SB Audience's maximum power, 3 dB above the RMS rating.
- Sensitivity is averaged over 1–18 kHz, with the driver mounted on SB Audience's H250 horn.
