3.5" Powered Studio Monitors
PreSonus - 'Eris 3.5'

PreSonus Eris 3.5

Active Media Reference Monitors Gone are the days where you had to spend a small fortune to enjoy precision sound, and PreSonus’s ‘Eris E3.5’ studio monitors are here to prove it! The Eris E3.5’s are nearfield monitors featuring tough woven composite woofers to deliver superb low-frequency reproduction with almost no distortion, and silk-dome tweeters to produce smooth and crisp highs.

The end result? Sound you can trust. This means that the mixes you create using your Eris E3.5’s will translate better from one stereo to another. This is what separates the E3.5’s from other speakers in this price range, whereas similarly priced speakers are engineered to make music sound better, the E3.5’s were made to reproduce audio with accuracy and precision.

Sound you can Trust

PreSonus Eris 3.5

hear everythingThe Eris-series of studio monitors are the choice of audio engineers the world over who need to hear every nuance of their recordings. Perfect for gaming and home video production, the Eris E3.5 uses the very same technology found inside the larger Eris models to produce studio-quality sound, with a rich and precise frequency response.

Woofers that Deliver a Cleaner Overall Sound


Smooth high end and wide sweet spotEvery Eris-series studio monitor utilizes a woven composite, low-frequency driver. The weave and nature of the Eris E3.5’s 3.5-inch woofer result in a more constant dispersion pattern throughout the frequency range, resulting in less time-smeared audio and cleaner overall sound.

The Eris E3.5 is equipped with a one-inch silk-dome tweeter that produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide dispersion pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear everything accurately.

Connect to Virtually any Line-Level Source

4K Recording

1/4" TRS / RCA inputs / 1/8" stereo unbalanced With three different types of audio inputs, it’s easy to feed audio to your Eris monitors from a mixer, an interface, a media player, or almost any other line-level source. The Eris E3.5 is equipped with rear-panel, ¼-inch TRS and RCA inputs, as well as front-panel ⅛-inch stereo, unbalanced line inputs for use with mobile audio devices.

With this selection, you’ll have no problem hooking your Eris speakers up with virtually any line-level source, including your smartphone or tablet. The loud, clear, front-panel headphone amplifier lets you work and play in stealth mode, without disturbing your housemates.

PreSonus ERIS 3.5 Active Monitor Speakers (Pair), 3.5" Woven Kevlar Driver, 25W Amplifier Per Side, 80Hz - 20kHz is rated 5.0 out of 5 by 2.
Rated 5 out of 5 by from PresSonus Eris 3.5 speakers I purchased these speakers to replace an ageing 2.1 Creative setup that I have been using for years. I needed to create space and wanted to lose the subwoofer. I decided upon the PreSonus Eris 3.5 speakers based on multiple online reviews and/or youtube videos. I am certainly no techno phobe and these speakers are for just general usage for me. I am not using them for sound editing or anything like that. However I can say that the sound quality is excellent, clear and crisp. Whilst they obviously won't compete on their own in bass terms against a 2.1 setup, I am extremely happy with how these sound. Build quality for the price is also very good, easy to set up etc. If you need bass you may need to look at other options for your setup. The purchase process through Scan was faultless and very fast. Highly recommended speakers based upon my experience and usage.
