I just purchased a pair of the Studio 530 and 590 speakers to replace some aging 4408a that I bought new in the 90s. I have to say that who ever designed these speakers did one hell of a job. They just sound simply wonderful. In my little studio Im using the 530s with a Crown D75 and the 590 in the living room with a pair of Pass amp camp amplifiers. Couldn't be happier. If your looking for assembled jbl speakers in my opinion these are a great deal.
And no I wont stop building. But my wife is happier with the look of these over the folded horns. A story for another day
