Compact 4.5-Inch Studio Monitor

The PreSonus Eris Studio 4 is a 50W 2-way active monitor built for accurate mixing in home studios and small professional rooms. Its 4.5-inch woven composite woofer and 1-inch silk dome tweeter deliver a frequency response of 55 Hz to 20 kHz. The custom EBM waveguide provides 120-degree horizontal dispersion for a wide sweet spot.

Suited for Critical Listening in Small Spaces

This monitor suits engineers who need detailed stereo imaging and controlled vertical dispersion to reduce desk reflections in compact environments. Buyers requiring deeper low-frequency extension below 55 Hz or higher SPL for larger control rooms should consider different solutions. The adjustable Acoustic Space settings help tailor the response to specific room acoustics.

50 Watts Class A/B Biamped Power

The biamped Class A/B amplifier delivers 50 watts of power to drive the woofer and tweeter separately, providing headroom for clean transient reproduction. This power rating determines the monitor's maximum output level and dynamic capability for nearfield monitoring tasks. The ported enclosure works with the amplifier to maximise bass response down to 55 Hz.

Questions about this item

What type of input does the Eris Studio 4 accept and what is the practical limit?

The Eris Studio 4 uses balanced TRS and unbalanced RCA analogue inputs; the signal chain is limited by the 50 W Class A/B amplifier and the 55 Hz – 20 kHz frequency response.

What physical space and mounting options does the 10.2-pound monitor require?

The compact 4.5-inch footprint fits on a standard desk or shelf; the rear-firing port needs a few centimetres of clearance from the wall, and the enclosure includes threaded inserts for optional wall or stand brackets.

How do I set up the Eris Studio 4 and which step is often missed?

Connect the mains lead, link your interface to the TRS or RCA inputs, set the Acoustic Space switch to Flat, -2 dB or -4 dB to match the monitor's distance from boundaries, then adjust the high and mid controls — many users forget to change the default Flat setting when the speaker sits close to a wall or corner.
