The mid and upper range Audio Physic speakers look great and are well built. Unfortunately, their bass response is sadly lacking. So, it really depends on the kind of music that you listen to. But, if your music goes down to the lower octaves, the Audio Physics simply don't have it. And, they are expensive. So, I suspect that's why you don't hear more about them. Finally, they have very limited distribution in the US, as was mentioned.
