Has anyone heard Pi speakers?

Since I have room for a cornerhorn type speaker, those Pi-7's look very interesting and, they are certainly reasonable in price. I know at first glance they look like a typical cheapo speaker but, after reading the Pi forum it appears that these speakers may be knocking on the door of high-end. Hard to tell though. Since kits are a big part of their business, most owners built them from kits. Very few have built the corner horns though and, it is difficult finding any comments on them.
