## Overview

The PreSonus Eris Studio 4 is a compact 4.5-inch 2-way active studio monitor designed for home and professional studios. Featuring a 50W biamped power system, it delivers up to 99 dB of balanced sound with extended bass down to 55 Hz and crystal-clear highs via a 1-inch silk-dome tweeter and EBM waveguide. Customizable acoustic tuning controls allow precise sound tailoring for any room, making it an essential tool for accurate music production and mixing in small spaces.

## Description

From the manufacturer Superior Sound for Small Studio Production. The PreSonus Eris Studio 4 combines sonic accuracy with precision controls and flexible connectivity to set a new standard for compact studio monitors. Designed for high-level performance in both home studios and professional mix rooms, its crystal clear low end and superior high-frequency response deliver honest, articulate sound in even the smallest of mixing spaces. Wide Sweet Spot and Lifelike Imaging. The Eris Studio 4’s custom-designed EBM (Elliptical Boundary Modelled) 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. Extended Lows and Clear, Natural Highs. Don’t be fooled by the Eris Studio 4’s compact enclosure! Its front-ported design and 4.5-inch, woven-composite, low-frequency drivers produce an accurate, smooth, and tight bass response with extended low end—all the way down to 55 Hz. A 1-inch (25 mm), ultra-low-mass, silk-dome tweeter combines with the EBM waveguide to ensure snappy, accurate transient reproduction for crystal-clear, natural highs. Driven by 50W of biamped power, the result is up to 99 dB of powerful, balanced, fundamentally honest sound that fills the room and a broader sweet spot for marathon mix sessions with a less-fatiguing listening experience. Want extra-deep low end? Pair compact Eris Studio 4s with PreSonus’ companion Eris Sub 8BT 8-inch subwoofer for powerful, ultra-low-frequency sound. You’re in Control. Precise Acoustic Tuning controls enable you to customise the Eris Studio 4’s response to ensure optimal performance in your room. In addition to continuously adjustable High Frequency and Midrange controls, a three-position Acoustic Space switch lets you adjust the bass response to compensate for speaker position near a wall or corner. A High Pass switch sets the low-frequency cutoff so you can match the Eris Studio 4s with a subwoofer.

Review: excellent - they sound great
Review: Amazing sound and quality build for the price. - Great sound, good tweeters, good bass, value is excellent for the quality you are getting. Easy to set up with its own power supply, with switches on the back for on/off. Note that no jack cables are included, only the power cables. No Bluetooth or wireless technology. I have the 5inch which is perfect fit for my desk, they could use a sub if you really need lower frequencies to shine through, but these are a great starting point and can do without a sub if you aren't producing/mastering sounds and need to hear those lower frequencies.
