Coaxial Studio Monitor for Mixing

The PreSonus Eris Pro 4 is a 4.5-inch active coaxial studio monitor built for mixing and critical listening. Its single point-source design aligns the 1-inch silk dome tweeter and 4.5-inch woven composite woofer for precise stereo imaging and a wide sweet spot. This configuration suits Dolby Atmos immersive rooms as well as traditional stereo setups. The monitor delivers 80 watts of power for detailed transient response and natural dynamics.

Sustained Output and Room Tuning

The ported enclosure and 80-watt amplifier allow the monitor to reach frequencies as low as 50 Hz with tight, controlled bass. Acoustic Space settings at Flat, -2 dB, and -4 dB compensate for placement against walls or in corners during long sessions. Additional high and mid frequency controls let you tailor the response to your specific room acoustics. These adjustments help maintain accuracy and reduce listening fatigue over extended periods.

Input Interface and Placement Limits

Balanced XLR, 1/4-inch TRS, and unbalanced RCA inputs provide flexible connectivity for various audio sources. The coaxial architecture creates symmetrical dispersion patterns that widen the usable listening area compared to conventional designs. Low-frequency extension stops at 50 Hz, so content requiring deeper sub-bass reproduction will need a separate subwoofer. The three-way Acoustic Space tuning addresses boundary interference but cannot eliminate all room-mode issues.

Questions about this item

How much power does the 80W amplifier draw and how hot does the cabinet get during all-day sessions?

The built-in 80 watt amplifier powers both drivers; the ported enclosure is designed to dissipate heat during extended use.

Which cables or audio interface outputs are required to connect the balanced XLR and 1/4" TRS inputs?

You need XLR or 1/4" TRS cables from a balanced line-level source; an unbalanced RCA connection is also available.

Will the 50 Hz low-frequency extension and coaxial dispersion integrate cleanly with an older subwoofer and near-field pair?

The 50 Hz - 20 kHz response and three-way Acoustic Space tuning let you match the monitor to existing subwoofers and room positions.
