The Illusio Alana is a dedicated satellite system; in other words, subwoofers are required.
We've paid a fair amount of attention to the radiation pattern. The Alana has a constant-directivity waveguide and uses pattern-matching in the crossover region, and its stand has an adjustable rear-firing driver. The intention of this unorthodox combination of parts is to combine some of the attributes of a good narrow pattern-speaker with some of the attributes of a good wide-pattern speaker.
Probably within the next week or so information about Illusio and/or the Alana will appear on James Romeyn's website:

And at some point in the not-too-distant future I'll start a relevant thread in the Desperate Dealers forum.
