About the PreSonus ERIS-PRO-8 8-Inch Active Coaxial 2-Way Studio Monitor

The PreSonus Eris Pro 8 is the flagship model in the Eris Pro series, featuring a powerful coaxial design that delivers a coherent, single-point source acoustic image. By centering the 1.25-inch silk-dome tweeter within the 8-inch woven-composite woofer, the monitor achieves exceptional phase alignment and a symmetrical dispersion pattern. This design ensures a wide, consistent "sweet spot" and superior spatial detail, making it a premier choice for high-end professional studios, critical mixing environments, and complex immersive audio setups like Dolby Atmos.

Driven by a robust 140W of Class AB amplification (75W LF / 65W HF), the Eris Pro 8 provides massive headroom and a deep, punchy low-end response that reaches down to 35 Hz. To ensure accuracy in any room, the rear panel includes a full suite of Acoustic Tuning controls, including a three-position Acoustic Space switch to manage bass buildup near walls and dedicated High and Mid-frequency adjustments. With balanced XLR, 1/4-inch TRS, and unbalanced RCA inputs, plus integrated mounting points for wall or ceiling installation, the Eris Pro 8 offers the versatility and transparency required for elite-level audio production.

FAQs about PreSonus ERIS-PRO-8 8-Inch Active Coaxial 2-Way Studio Monitor

What is the main advantage of the Eris Pro 8's coaxial design?

By placing the 1.25-inch silk-dome tweeter in the center of the 8-inch composite woofer, the single-point-source design achieves acoustic time-alignment across all frequencies. This delivers precise stereo imaging, incredible clarity, and a wide, consistent acoustic sweet spot.

Are PreSonus Eris Pro 8 monitors sold individually or in pairs?

The Eris Pro 8 studio monitors are sold individually as single units. You will need to purchase a quantity of two to build a standard stereo setup.

How much power does the internal amplifier supply?

The monitor features a bi-amped Class-AB design delivering 140 watts of total continuous power. It splits 75 watts to the 8-inch low-frequency woofer and 65 watts to the high-frequency driver for high SPL output and clean headroom.

What audio input connections are available on the rear panel?

It offers balanced XLR, balanced 1/4-inch TRS, and unbalanced RCA input connections. This versatile input section allows seamless connection to professional audio interfaces, monitor controllers, and mixing boards.

Does the Eris Pro 8 provide acoustic room-tuning controls?

Yes, the rear panel features Acoustic Space switches (0, -2 dB, -4 dB) to eliminate bass buildup when placed against walls or corners, plus Mid and High tuning controls (±6 dB). It also includes a selectable Low Cut filter (Flat, 80 Hz, 100 Hz) for subwoofer integration.

What is the low-frequency limit of this 8-inch studio monitor?

Thanks to its large 8-inch woofer and front-firing bass-reflex port, the Eris Pro 8 reaches down to 35 Hz. This allows you to accurately monitor sub-bass frequencies without requiring an immediate subwoofer addition.

Can these monitors be wall- or ceiling-mounted for Dolby Atmos setups?

Yes, the cabinet includes built-in mounting provisions for optional wall and ceiling brackets. Its single-point-source coaxial dispersion makes it an exceptional choice for surround sound and Dolby Atmos immersive audio configurations.

What built-in safety features protect the speaker components?

The Eris Pro 8 includes active protection against RF interference, output current limiting, over-temperature protection, and subsonic filtering. It also features turn-on/off transient protection to prevent annoying pops from damaging the drivers.
