  • Xmax is quoted one-way (peak), not peak-to-peak.
  • Sensitivity measured at 2.83V/1m.
  • Power handling (RMS) is the AES rating: 2 hours of pink noise (6 dB crest factor), Fs to 10 × Fs, in free air, on the minimum impedance. Program power is SB Audience's maximum power, 3 dB above the RMS rating.
  • Sensitivity is averaged over 50 Hz–1 kHz.
