Presonus Eris Pro 4 Active Studio Monitor (Single Unit)

General

The PreSonus Eris Series also serves up coaxial studio monitors for super-transparent, near full-range sound without any phase issues: the Eris Pro models. This is the Eris Pro 4, and it's been designed with Dolby Atmos in mind. The idea behind a coaxial studio monitor like this one is that the woofer and tweeter are in the same place. Here, the tweeter sits directly on top of the woofer, which means that the trebles travel exactly the same distance to the listener as the low and mid frequencies. This eliminates the subtle phase differences that you get with non-coaxial monitors, allowing you to to mix your tracks down with maximum sonic accuracy.
