Whatever about the sound (to be determined), I find the rounded bottom cognatively dissonant. One expects a curve to be on the top of an object. Imagine a neoclassical building where the romanesque windows were upside down.
Also, I really can't see why they did it from a structural engineering point of view. It adds a lot of complexity to the structure for no benefit.
As regards the pricing, it looks pretty competitive for the specification - assuming the sound lives up to it, of course.
And PS is planning a number of trickle down models which, of course, is where they will make their real money and recoup their R&D costs.
