I certainly share your enthusiasm for 2-way horn/woofer designs when done well. Such systems tend to be fairly high efficiency, which in turn gives us better dynamic contrast and reduced amplifier requirements. The downside is the larger enclosure required for good bass extension.
I don't do active monitors because the relatively high efficiency of a 2-way horn/woofer system gives us the option of making a tube-friendly design, and I think there are more people with tube amps looking for suitable speakers than there are people looking to get away from separate amps and into active speakers. Also, I feel like I can offer better bang-for-the-buck in a passive format.
