Kasboot, has the RL-1 shown up at your house yet ? I'd be curious as to your feelings about how it works once it has settled in somewhat. I've somewhat followed the "metamorphisis" of this speaker and i can see that it has changed quite a bit since its' first inception.
With that in mind, i wonder just how much it has changed ? In Steve's initial "white papers" on it, i could see quite a few ways to improve the design and widen the frequency response. I also didn't care for how he was coupling the motor to the cone. Then again, this was strictly a prototype. I assume that he has come up with something that is a little more reliable and repeatable since he's planning on doing this on a small production basis. Since he hasn't updated any of the information since the earlier prototype research, i really don't know what to expect out of them. Especially since he hasn't posted any frequency responce or dispersion charts, etc...
This design is also not quite "crossover-less" or "one driver". I'm assuming that he's using a 6 dB per octave on the tweeter (one capacitor), which would be the "top grade polypropylene minimalist crossover design".
As to what "sparked" his interest in doing a project like this, look back at the "Wild DIY Projects" covering the "radial speaker" and read that. You might be able to guess who the person is that contacted him about the original Ohm Walsh drivers and referred Ole Thoft with his "Conus" project to Steve. The name of that person is....
