PreSonus Eris 3.5 Studio Monitor (Pair)

1500000407950


Compact dimensions, flexible connectivity and adjustable acoustic tuning make the PreSonus Eris 3.5 second-generation powered studio monitor pair a practical solution for desktop music production, mixing and multimedia listening. Each monitor features a 3.5" woven glass-fiber composite woofer and 1" silk-dome tweeter, combining defined low frequencies with clear high-frequency reproduction. Updated second-generation voicing refines the monitors' response, while 50W of total Class AB amplification provides power for nearfield listening. Rear-panel high- and low-frequency controls allow users to adjust the sound to their room and speaker placement. Balanced 1/4" TRS and unbalanced RCA inputs accommodate common studio equipment, while front-panel auxiliary and headphone connections offer convenient access for everyday listening. Together, these features make the Eris 3.5 monitors a versatile option for musicians, producers and creators working in space-conscious studios.

Two-Way Driver Design for Detailed Nearfield Monitoring

Each Eris 3.5 monitor combines a 3.5" woven glass-fiber composite woofer with a 1" silk-dome tweeter, dividing low- and high-frequency reproduction between dedicated drivers. The woofer provides controlled bass and midrange response, while the tweeter reproduces upper-frequency detail across a broad listening area. Updated second-generation voicing delivers improved low-frequency performance and smoother crossover transitions, supporting clarity when evaluating instruments, vocals and mixes. With an 80Hz–20kHz frequency response and peak output of 98dB SPL at 1 m, the Eris 3.5 monitors are designed for close-range listening in desktop recording and production environments.

Adjustable Acoustic Tuning and Flexible Rear-Panel Connectivity

Rear-panel high- and low-frequency acoustic tuning controls provide ±6dB of adjustment, allowing users to shape the monitors' response according to their listening environment. These controls are particularly useful when speakers are positioned near walls or on desktop surfaces, where room acoustics and placement can affect perceived tonal balance. Balanced 1/4" TRS inputs accommodate compatible audio interfaces and mixers, while unbalanced RCA inputs provide connections for additional wired audio sources. This combination of acoustic adjustment and input flexibility helps users integrate the Eris 3.5 monitors into a range of home recording and desktop listening setups.

Convenient Front-Panel Connections for Everyday Studio Use

A front-panel stereo 1/8" auxiliary input makes it easy to connect compatible audio sources without accessing the rear of the monitors. An adjacent 1/8" headphone output automatically mutes the speakers when headphones are connected, allowing users to move between speaker monitoring and private listening. These accessible connections complement the compact design, making the monitors practical for workspaces where equipment needs to serve multiple purposes. For musicians, producers and content creators seeking adjustable sound, flexible connectivity and a compact footprint, the PreSonus Eris 3.5 powered studio monitor pair provides a straightforward solution for nearfield monitoring and everyday listening.
