@inorganic Yes, the famous ATC midrange. >300-3k. They used to sell them, but the mid driver is their bag. Guzauki-Swist is using that driver in a $30k system. Not sure if anyone else is able to get them from ATC at all now.
I have a very different approach to midrange. Midbass and low mid coherence is very important. I'm a baritone vocalist and bass guitarist, so I don't like it when the "power zone" is disembodied from the low midrange.
Most musical fundamentals are found between 150 and 600hz. This is what people people call "warmth" in music (trust that I'm willing to die on this hill, warmth = low midrange). That is the range of the fundamental tones of our voices.
330hz, the typical crossover point for the famous ATC 3" dome mid, this right in the heart of what we consider to be musical frequency. It is the critical midrange.
My design uses a 5.25" midrange crossed nearly 200hz lower. Of course, such a large midrange will beam if it is crossed too high, and like any 5" or larger driver (that I've found) the response starts to lose precision above 1000hz.
For many people, upper midrange, 1k-3k is the critical zone. Certainly, those frequencies are more present - they are what we call "presence" when we are discussing audio.
Our tweeter is planar, and we cross it much lower than standard, even lower than Dutch & Dutch 8c. It covers from 1k - 35khz, a phenomenal range for a single driver. What those numbers don't tell you is the phenomenal resolution of both detail and dynamics.
The system uses two critically dampened cabinets. We will include an adjustable, non-resonant pole, so that the top will sit at the optimum height. In practice, the mid and top would be fairly close together, as the low driver will be about 20 inches off the ground. There will also be the option of using a very hefty stand and fully decoupling the bass driver from the floor.
Modular approaches are not as easy to market. Fortunately, this is not modular. The active electronics are all contained within the bass unit, and although the top *could* be connected to another amp, this is forbidden, as without the active electronics, the drivers would certainly be damaged. Also, who wants to listen to music without low frequencies?
It can be set up in different ways, depending on what is required. With 1800 watts for the whole system, it could serve as a PA system for a small party. The poles will allow for standing-height listening, although that might be wishful thinking at this point.
