Based on description and listening, that seems similar to the 110HT series.Nothing like answering a two year old question.
Jeff did send me a prototype speaker. I don't know if he ever decided to finish it so I did not publish the results. It was a single, coaxial driver. Here is its response:

They need to be up against a wall or ceiling for low-end extension down to 80hz, but that's how most people use them.
I find that the wide directivity and good verticals are really nice for surround/ceiling use.
The wide directivity gives a more immersive experience and covers more seats.
The vertical directivity ends up being a big deal, since seats are often vertically off-axis to surround and ceiling speakers.
