PreSonus Eris E3.5 Studio Monitors Review


PreSonus is an established name in the studio monitor market and has many models to offer. PreSonus Eris E3.5 is the smallest in the range, at a budget price, but with a high-quality sound, perfect for small home studios, YouTubers, software developers, and video games designers.


  • Compact and minimalistic design
  • Accurate, balanced sound
  • Large soundstage
  • Affordable
  • Can stand everyday use for an extended period
  • Excellent sound reproduction for recording music, producing videos, and gaming.


  • Narrow sweet spot
  • If you want heavier bass, you need a subwoofer.


Often, something cheap has terrible quality, but that is not the case with the PreSonus Eris E3.5.

While the parts are mostly plastic, they are well constructed and provide the right balance between the price and the quality. And they look nice too. The cabinet is MDF (medium density fiberboard) that is vinyl laminated.

The design is clean, eye-pleasing with many cool features. The matte black vinyl coating is finger-proof. The look is minimalistic, with just blue accents on the woofer and PreSonus logo.

There is the power on/off, volume knob and jacks for an AUX input, and headphones on the left speaker’s front. An integrated stereo headphones amplifier is built-in in E3.5.

There is a one-inch silk dome tweeter and 3.5 inches woven Kevlar woofer on the front panel.

The left speaker is the active one, while the right speaker is passive.

That’s why on the rear end of the left speaker are acoustic tunning controls, two one-quarter TRS jack inputs, two unbalanced RCA jack inputs, and an IEC connector to plug in the power cord. The left PreSonus Eris E3.5 has a total of 25 watts per channel Class AB amplifier. The right speaker connects via included speaker wire. If you prefer more bass, you can add a subwoofer.

The engineers have placed a range of features into these monitors. The RF is a common problem with many speakers, so that’s why E3.5 has shielding to minimize any possible interference from other electronics. Also, there is prevention from overheating, output current limiting, and protection from subsonic frequencies.

As mentioned before, these speakers are ideal for small studios because of their power, packed in a small package.

The speakers’ size is 5.6 x 6.4 x 8.3 inches (W x D x H), allowing them to be on a desk, mounted on a wall, on a shell, etc. They are also lightweight, with just 2.9 kg. Their size allows you to place them anywhere you like. Keep in mind that although E3.5s are professional studio monitors, you can use them at home or work.

Sound quality

Audio quality is the most important thing about the speakers, and be sure that you will be amazed by what these speakers can do. Highs are crisp, clean without signs of fatigue, while lows are impressive and show presence more extensive than some other larger woofers can do. Being balanced all the way, these speakers do not lack mid-range either.

Many monitors find it challenging to produce a soundstage when placed near the listener, but not PreSonus Eris E3.5. They even give you an illusion that more prominent speakers are playing.

These speakers will catch every beat, no matter if the volume is high or low. Even at higher levels, the audio quality stays the same, and they can handle different music and media.

E3.5s are not too heavy in the low-ends, but the sound is clean, punchy, without getting muddy. Because the high-end is fantastic, you will have no problems hearing all instruments precisely if you use them to record music or mix.

To get the best possible sound, you need to do calibration to fine-tune the speakers according to your room.

The first calibration should be about the volume of the sound. For a small home studio, the ideal is 75 to 80 dB. If space is more extensive, you should use 85 dB.

The second step is to calibrate the stereo image of the sound. You want both, left and right sides to have the same volume by using the volume buttons on the monitor’s back.

You can use two pieces of equipment for this calibration, a tone generator that makes pink noise and an SPL meter. There is a free app for smartphones that serves as an SPL meter, performing C-weighted and slow response measurements. Most of the recording apps have a built-in tone generator. You need to have pink noise and be able to adjust the volume.


Compact monitors have more or fewer flaws in different areas. It isn’t easy to find one that can be great at multiple fields, and PreSonus Eris 3.5 is as close to perfect as it can get.

These speakers with great design and options for sound adjustments are right on the spot. Don’t get fooled by the low price. These are serious players in the audio market.
