PreSonus Eris Pro 8 Active Coaxial Studio Monitor

With a radical design that combines an 8" woofer and 1.25" tweeter in one coaxial driver, Eris Pro 8 monitors fill the room with consistently accurate sound.

The Eris Pro 8's coaxial design provides a single acoustic point source that creates a natural listening experience, revealing the subtlest nuances in your recordings. Combined with a punchy low-end that defies its compact size, the Eris Pro 8 provides a superior listening experience for both home studios and professional mix rooms.

Get a closer look at Eris Pro Series monitors in this video from PreSonus:

A 1.25-inch, ultra-low mass, silk-dome tweeter ensures snappy, accurate transient reproduction, while an 8-inch, woven-composite woofer offers tight, clear bass, with plenty of punch and no flab. The symmetric coaxial design provides a consistent acoustic center and superior phase alignment between components to deliver a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns - making the Eris Pro 8 ideally suited for immersive Dolby Atmos rooms and stereo mix environments alike.

Acoustic tuning controls and a three-way Acoustic Space control lets you accurately configure the Eris Pro 8 for your room. Flexible input options enable connection of almost any line-level source, from mixers to audio interfaces and more. Provisions for wall and ceiling mounts make it easy to integrate Eris Pro 8 monitors into any stereo or multi-channel system.
