The Presonus Eris Pro 4 reference monitors redefine audio precision through a single point-source coaxial design, delivering clear and accurate sound reproduction. This innovative design ensures superior phase alignment, creating a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns. Uniquely advantageous for both Dolby Atmos immersive rooms and stereo mix environments.

Key Features:

  • Coaxial Design - The single point-source coaxial design optimizes phase alignment, providing a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns.
  • Immersive Sound - Ideal for Dolby Atmos immersive rooms, the Eris Pro 4 offers a finely detailed transient response and stunning dynamics, ensuring a natural and less fatiguing audio experience.
  • Ultra-Low Mass Tweeter - The 1-inch ultra-low mass, silk-dome tweeter ensures snappy and accurate transient reproduction, contributing to the monitors' exceptional audio clarity.
  • Woven-Composite Woofer - The 4.5-inch woven-composite woofer delivers tight, clear bass with ample punch and no flab, enhancing the overall audio performance.
  • Ported Enclosure - The ported enclosure, combined with 80 Watts of power, allows the Eris Pro 4 to reach down to 50 Hz, ensuring a rich and full low-frequency response.
  • Acoustic Tuning Controls - Tailor the monitors to your room with acoustic tuning controls, while three-way Acoustic Space tuning compensates for speaker placement effects against walls or in corners.
  • Flexible Input Options - Connect almost any line-level source with ease, from mixers to audio interfaces and more, ensuring compatibility with various audio setups.
  • Easy Integration - Provisions for wall and ceiling mounts make it effortless to integrate Eris Pro 4 monitors into any stereo or multi-channel system, offering flexibility in placement.
