I am not sure why they were 'so expensive to build' compared to????. They are very good but certainly there are other speakers out there as good or maybe (BIG RISK SAYING THIS) even better. Granted, the S-150 was a class act and not easy to follow.
But get your ears out there and do so more listening, you might be surprised.
With the numerous companies out there, big and small building quality loudspeakers I don't understand why some folks feel they've been cheated or something. With the exception of those still waiting for parts, etc.
It's not the end of the world, if anything it presents a new opportunity or challenge.
