I measured the 811 horn (on-axis) with a variety of networks. You'll notice the ones without CD compensation had response that was nearly flat or just slightly falling as frequency rises. Both are pretty natural sounding. The ones with CD compensation showed response that was rising, and they sounded a little too bright.
