Hmmmm I've always greatly enjoyed your knowledge when you post do you mind just briefly explaining the issues with there design? The one in the past for starters. I've learned a lot from your explanations in other threads
That is the problem. They have never opened up what they did to peer review. All we know is that the channels are somehow blended and games with phase are involved. All of this sounds highly suspect on the face if it.
The results previously gave a superficially impressive sort of sound everywhere on pop music but try and get it to make a piano sound anything close to a real one and the jig was exposed.
The point is that when manufacturers take off on these weird tangents, then more often than not it is an admission of not being able to properly engineer from known principles, which is likely the issue here. Dealers are having trouble almost giving away their current towers with price cuts galore.
The fact is that if you have a speaker with good and flat FR and reasonably time coherent and with wide even dispersion then that speaker will deliver a sound stage with tremendous width, sense of space and good imaging at the same time. Of that I can be certain as I do know how to engineer for that.
When I looked into the last Polk tower a member was having trouble with, the neglect of known basic principles was truly astonishing.
I will pay more attention if Polk can actually produce and market a decent speaker adhering to first principles.
