PreSonus Eris 3.5 2nd Gen Studio Monitors (Pair)

PreSonus Eris 3.5 2nd Gen – Honest Desktop Monitoring, Pair

The PreSonus Eris 3.5 second generation is a pair of compact powered studio monitors for desks where music is made, edited or mixed. Each cabinet pairs a 3.5-inch woven composite woofer with a 1-inch silk-dome tweeter, driven by built-in Class AB amplification, and the tuning aims at accuracy rather than flattery: what is wrong with a mix stays audible, which is exactly what a monitor is for.

The second generation refines the original design with updated tuning and a wider sweet spot, so the balance you hear stays more consistent as you move around the desk while you work.

Why small monitors need tuning controls

Desktop monitors rarely sit in ideal positions. They work close to walls, on desks that reflect sound, and often in corners that exaggerate bass. The Eris 3.5 gives you high and low frequency tuning switches on the rear panel so you can trim the response to the position the speakers actually occupy, instead of fighting the room with EQ on every mix. Set them once for your desk, and the reference you work against stays stable from session to session.

Connections for a working desk

Balanced quarter-inch TRS inputs connect cleanly to an audio interface, while RCA inputs suit DJ controllers and consumer sources. The front panel carries the controls you touch daily: a volume knob, a headphone output that mutes the speakers for late-night editing, and an auxiliary input for quickly checking a mix against a phone. That layout keeps the desk workflow fast, with no reaching behind cabinets mid-session.

Who these suit

For a first studio, a video editing bay, a podcast setup or a small production room, the Eris 3.5 pair delivers the essential studio-monitor behaviour at a sensible size and cost: a balanced, unhyped sound, useful connections and cabinets that fit on a real desk. They are equally at home for serious multimedia listening, where the same accuracy that helps a mix also makes dialogue clear and music detailed.

If your mixes need to travel – to headphones, to a car, to a client’s speakers – starting them on monitors designed to tell the truth is the cheapest upgrade you can make.

Set up once, then forget them

Setup takes minutes: place the pair either side of your screen at ear height where you can, connect the included speaker wire between the cabinets, plug in your interface or controller, and set the rear tuning switches for your placement – flat on a desk away from walls needs little correction, while a corner position usually benefits from trimming the low end. From then on the Eris 3.5 pair asks nothing of you. There is no amplifier to switch on separately, no settings buried in software, just a volume knob where your hand expects it and a reference you can trust every time you sit down to work.
