Talked w/my local dealer who knows Michael Kelly quite well and he informed me that the Aerial 5B bookshelf speaker has been discontinued. This fall the new 5 will be out. It basically will be the same design as the 6&7T models. It will also not be a sealed design like the 5B and older 5. It will be rear ported. I suspect he will be using the same soft dome tweeter found in the newer models. The dealer was not sure on the price but he thought it will be around $3,000.:b
