Shipping in May, according to their website. I used to own 3.1 and sold them eventually for few couple of deficiencies that are supposedly addressed in the new design. Will be curious how they turn out. They still did few things like no other speaker, like when you hear a sound and you don't know where the sound is coming from even though you might be almost right in front of the driver.Anyway, would love to hear what people think about them and their first impressions.
