From what I can tell, so far, Richer Sounds in the UK has listed the Aero line.
The Aero 2 bookshelf @ £349.95, Aero 3 surround @ £299.95, Aero 5 center at @ $249.95, Aero 6 tower @ £649.95 and the Aero 9 Subwoofer @ £449.95. The prices on the speaker models are per pair.
While using the currency converter for the American dollar, the Aero 2 bookshelf is $555.65 per pair. My guess is that it will be closer to $560.00 per pair. The Aero 6 tower is $1031.99. My guess would be closer to $1,035.00. This is only a guess on my part.
