Manufacturer's ID: ERIS-E4.5-BS

When you’re ready to get serious about recording, it’s time to step up to PreSonus Eris-series studio monitors. Cheap computer speakers and home-stereo speakers won’t reveal the truth about your mix. They aren’t designed for that. In contrast, Eris speakers are real studio monitors, delivering a very accurate response with a tight bass and very clear upper end. That’s what you need in a home studio.

Clean overall sound, smooth high end, and a wide sweet spot

Every Eris-series studio monitor utilizes a woven composite low-frequency driver. The weave and nature of the Eris E4.5 speakers’ 4.5-inch woofer result in tight bass that you can feel, as well as a cleaner overall sound. The one-inch silk-dome tweeter produces a smooth and refined sound, accurately reproducing transients and high frequencies. The tweeter is designed to radiate sound with a fairly wide pattern, creating a large optimal listening area or “sweet spot” so you can move around and still hear an accurate stereo image. With 25 watts per side of onboard power, Eris 4.5 monitor speakers pack a serious punch, while still delivering clear, accurate audio.

Easy-to-use controls.

A speaker’s response is affected by where you place it and the acoustics of your space. That’s why Eris E4.5 active media reference monitors offer controls to adjust the high- and low-frequency content, so your speakers always sound their best. A convenient front-panel volume knob sets both the speaker level and the integrated headphone amplifier’s level.

Flexible input options.

With three different types of audio inputs, it’s easy to feed audio to your Eris E4.5 monitors from almost any source with a line output. Play games, listen to music, and even create content with a computer, media player, mixer, or other line-level source using the Eris E4.5 speaker’s rear-panel, 1 ¼-inch TRS and RCA inputs and front-panel 1/8” stereo inputs. A loud, clear, front-panel headphone amplifier lets you work and play in stealth mode, without disturbing your housemates.

Accuracy defined.

Like all PreSonus speakers, the Eris E4.5 offers consistent, accurate listening, with the smooth and even frequency response that has made Eris studio and media reference monitors popular around the world. Their compact and powerful design makes them an ideal solution for any small space. Want extra-deep low end? Pair the compact Eris E4.5 with PreSonus’ powerful Temblor® T8 active subwoofer for a truly full-range sound system that fits almost anywhere.

Bundled Software

Did you know? PreSonus studio monitors and media reference monitors include a special edition of Studio Magic, a suite of over $1000 USD worth of music software including Studio One Prime and more plug-ins, loops, virtual instruments, effects, and tutorials than you may ever need. The Magic edition of Studio One Prime is compatible with all of the included plug-ins, of course, and because they're included in VST, AU, and AAX formats, you can also use them in any DAW you’d like.

Milo W. - 13/3/2018

Awesome set of mini moniters, currently used as PC speakers alongside a Helix & Scarlet interface. Slight crackle in background when no sound coming through speakers

David B. - 25/2/2018

Good solid speakers, Easy to set up and adjust. The reviews say it all which is why I picked these speakers over the others around the same price bracket. There's an ongoing argument about 'running in' speaker / headphones by playing white noise throught them over an extended period. All I can tell you is it worked wonder on my AKG K702 headphones, and after 20 hours doing the same through the E4.5 speakers, it sounds like they are starting to open up from how they sounded on first listen. Just another 100 hours to go and we'll be there.

russell w. - 15/8/2017

Good all rounders. Decent output and solid bass handling and great shape.

D.. - 22/2/2016

Great sound from small units - well defined and airy, Surprising coverage at the low end. Many opportunities for tailoring the sound.

J.. - 22/2/2016

Just right for my home studio
