Powerresponse is uniform, with smoother variations on and off-axis.
功率响应一致，同轴和离轴变化更为平稳。

This figure shows that the powerresponse is very smooth throughout the whole frequency range, and the controlled off-axis roll off of the tweeter.
这幅图表明，频率响应是非常平滑地贯穿整个频率范围和高音喇叭的受控离轴滚降。

Interference (or 'lobing') between the two units causes a dip in powerresponse around this frequency, with a peak above it due to their differences in directivity.
