PreSonus Eris Studio 4 Studio Monitor

The Eris Studio 4 generates up to 99 dB of clear, transparent sound with its 4.5-inch woven composite low-frequency driver and a 1-inch silk dome tweeter, powered by 50 W of Class AB bi-amplification. The ported enclosure delivers deep, tight bass, while an EBM waveguide provides a broad, controlled sweet spot and detailed high-frequency reproduction. Designed for superior performance in both home studios and small professional mixing rooms, the Eris Studio 4 combines flexible connectivity with precise sound reproduction that sets it apart.

• 4.5-inch woven composite low-frequency driver
• 1-inch silk dome high-frequency driver with ultralow mass
• 120˚ (H) x 60˚ (V) EBM waveguide for a wide listening sweet spot
• Front acoustic port for enhanced bass response and internal resonance suppression
• 50W Class AB bi-amplification
• Frequency response from 55 Hz to 20 kHz
• 99 dB SPL (peak, at 1 meter)
• Acoustic tuning controls: HF (±6 dB, continuously variable); Midrange (±6 dB, continuously variable); Acoustic space (flat, -2, -4 dB); High-pass filter (off, 80 Hz, 100 Hz)
• RF interference, output current limiting, thermal protection, transients, subsonic protection, and "soft start" amplifier function (eliminates pops on power-up)
• Internal power supply with IEC connector and power switch with LED indicator
• Balanced XLR and ¼" TRS inputs, unbalanced RCA inputs

The custom-designed EBM (Elliptical Boundary Modeled) waveguide offers superior high-frequency response, allowing you to hear the finest details in your mix, while the wide 120-degree horizontal dispersion creates an expansive listening area with realistic stereo imaging. The narrow vertical dispersion reduces desk reflections, and the silk dome tweeter ensures agile, precise transient reproduction.

The 4.5-inch woven composite driver produces clear, punchy bass with ample power, challenging the compact size of the Eris Studio 4. The ported enclosure combined with 50 W of bi-amplified power maximizes bass response, allowing the Eris Studio 4 to reach an impressive 55 Hz. Built for exceptional performance in both home and small professional studios, the Eris Studio 4 offers flexible connectivity and precise sound that truly stands out.
