Notes
1. AES Standard (35 to 350 Hz) Program 1600 Watts
2. Sensitivity is derived from the sine wave response between 50 - 350 Hz at 5W/2M
using Zmin. It is then scaled to represent 1W/1M. It should be noted that not all
manufacturers’ sensitivity figures are based on this AES Recommended Practice.
3. In less demanding applications, the crossover point may be higher.
