Presonus Eris Studio 4 Active Studio Monitors (Pair)

The Eris® Studio 4 sets a new standard for compact studio monitors. With its surprising amount of low-end and wide, well-controlled sweet spot, you can enjoy premium, accurate monitoring in even the smallest of mixing spaces.

Main Features

• 4.5-inch, woven-composite, low-frequency transducer
• 1-inch (25 mm), ultra-low-mass, silk-dome, high-frequency transducer
• 120˚(H) x 60˚(V) EBM waveguide for wide sweet spot
• Front-firing acoustic port for superior bass-frequency reproduction and optimized, resonance-suppressing internal bracing
• 50W, Class AB biamplification
• 55 Hz to 20 kHz frequency response
• 100 dB SPL (Peak, @ 1 meter)
• Acoustic Tuning controls: HF (±6 dB, continuously variable); Midrange (±6 dB, continuously variable), and Acoustic Space (flat, -2, -4 dB), plus highpass filter (Off, 80 Hz, 100 Hz)
• RF interference, output-current limiting, over-temperature, transient, subsonic protection and amplifier “soft start” feature (eliminates popping on power-up)
• Internal power supply with IEC connector and power switch with on/off LED
• Balanced XLR and ¼-inch inputs and unbalanced RCA inputs

The Eris® Studio 4 drives up to 99 dB of crystal-clear, transparent sound with its 4.5-inch woven composite low-frequency driver and 1-inch silk-dome tweeter, powered by 50W Class AB biamplification. The ported enclosure creates a deep, tight low-end, while an EBM waveguide provides a wide, controlled sweet spot and detailed high-frequency reproduction. Designed for superior performance in both home studio and small professional mix rooms, the Eris Studio 4 combines flexible connectivity with sonic accuracy that puts it a class all its own.

The Eris® Studio 4 sets a new standard for compact studio monitors. With its surprising amount of low-end and wide, well-controlled sweet spot, you can enjoy premium, accurate monitoring in even the smallest of mixing spaces.

The custom-designed EBM (Elliptical Boundary Modeled) waveguide provides superior high-frequency response that allows you to hear the finest details in your mix, while a wide 120-degree horizontal dispersion creates a broad sweet spot with lifelike stereo imaging. Narrow vertical dispersion reduces reflections from your desk, and a silk-dome tweeter ensures snappy, accurate transient reproduction.

The 4.5-inch, woven-composite, low-frequency driver produces tight, clear bass with plenty of punch that defies the Eris Studio 4’s space-saving size. The ported enclosure and 50W of biamped power combine to maximize bass response and allow the Eris Studio 4 to reach down to an astonishing 55 Hz. Designed for superior performance in both home studio and small professional mix rooms, the Eris Studio 4 combines flexible connectivity with sonic accuracy that puts it a class all its own.
