Here is the full Studio 5 family.
Looks like the 530 BS drew the short straw this time (no discount on it)
Best-in-class JBL studio 5 home speakers & subwoofer delivers robust sound at a professional level and can work with multiple power amplifiers and fit any home decor.

Also, I like to point out that the 590 is a very large tower. That may not matter, but it is about 50" tall and 13" wide and 16" deep. In a great room, it is an easy fit, but for an office or bedroom you might feel a bit intimidated!
