Notes

1. Subject to room loading. Specified for 8 feet actual distance between HD-1 cabinet and a single boundary surface.

2. One-third octave resolution.

3. Amplifier wattage rating based on the maximum unclipped burst sine-wave rms voltage that the amplifier will produce for at least 0.5 seconds into the nominal load impedance.

Unless otherwise specified, all acoustical measurements are performed at 1/2 meter from front baffle on tweeter axis. Acoustical decibels are specified re 20 uPa.
