PreSonus Eris Pro 4 (Single)
SKU: P277-7506-129
The Eris Pro 4 reference monitors employ a single point-source coaxial design for clear and accurate sound reproduction. This design provides superior phase alignment between components and delivers a wide sweet spot, precise stereo imaging, and symmetrical dispersion patterns - unique advantages for Dolby Atmos immersive rooms as well as stereo mix environments.
The Eris Pro 4 also delivers finely detailed transient response, and stunning dynamics that create a natural and less fatiguing listening experience. A 1-inch ultra-low mass, silk-dome tweeter ensures snappy, accurate transient reproduction, while a 4.5-inch woven-composite woofer offers tight, clear bass, with plenty of punch and no flab. A ported enclosure and 80 Watts of power allows the Eris Pro 4 to reach down to 50 Hz.
Acoustic tuning controls let you configure the Eris Pro 4 for your room and three-way Acoustic Space tuning can compensate for the effects of speaker placement against a wall or in a corner.
Flexible input options let you connect almost any line-level source, from mixers to audio interfaces and more. You'll have no problem hooking your Eris speakers up to virtually anything. Lastly, provisions for wall and ceiling mounts make it easy to integrate Eris Pro 4 monitors into any stereo or multi-channel system.

Accurate transient reproduction.
Consonant sounds in speech, percussion, and attack and decay of musical instruments are all transient signals. When reproduced accurately, the result is sonic transparency, definition, and intelligibility. With their excellent transient reproduction, Coaxial speakers minimize distortion and produce clean, clear, consistent audio at any SPL.
