It looks like eD speakers are REALLY starting to take off. I keep seeing posts that such and such model aren't in stock.
Back when I ordered mine, I had it all, except for the sub, in 3 days. And I have at least one of each model speaker in my setup.
Speaking of setup, I recently bought a Yamaha RX-Z11 flagship receiver. This thing is a beast. And wow, do the eDs sounds great paired with it. I watched some action scenes at -10db without the family around, and they sounds amazing. Not that loud is a sign of quality by itself, but boy, can they get loud!
