When Size Matters
For an extended low-frequency response and a bit more muscle, step up to the Eris E8. With its 8-inch, Kevlar low-frequency transducer, driven by a 75 watt, Class AB power amplifier, it can range down to 35 Hz. The E8 monitor can reach all the way to 22 kHz, thanks to a 1.25-inch (32 mm), silk-dome, high-frequency tweeter. However, the E8’s tweeter is driven by a heftier 65W, Class AB amplifier. With its extra juice, the E8 can deliver up to 105 dB SPL, peak.

The Eris E8 speaker has front-ported enclosures made of vinyl-laminated, medium-density fiberboard (MDF).

The Eris E8 powered studio monitor provides balanced XLR, balanced 1/4 in. TRS, and unbalanced RCA line-level inputs. When both balanced connections are in use, the TRS input will supersede the XLR input. The RCA input is summed into the signal path.

With this selection, you’ll have no problem hooking your Eris speakers up with virtually any line-level source. (If your signal source has unbalanced, 1/4 in. TS outputs, simply use a 1/4 in.-to-RCA adapter or adapter cable.

You’re in control!
Today’s music producers deal with a wide variety of musical genres and often work in more than one location. It’s easy to take your Eris speakers with you when you want to work in a different space. It’s almost as easy to customize their sound for your room and type of music. The most basic control is the Input Gain, which determines the signal level before it reaches the power amp. This is part of gain-staging your overall system—that is, setting the levels for every part of the recording chain in order to get the optimal level of clean audio all the way through. Once you’ve gain-staged your system, you can leave this control alone.

The Eris E8 provides three EQ controls in its Acoustic Tuning section: High, Mid, and Low Cutoff. These controls enable you to fine-tune the monitors and even to broadly approximate the sounds of different types of speakers so you can hear what your mix might sound like, for instance, on a car stereo or portable radio. The Low control also is useful when using the E8 with a subwoofer.

In addition to the Acoustic Tuning controls, Eris speakers offer a three-position Acoustic Space switch. This switch controls a second-order, low shelving filter that cuts the level of all frequencies below 800 Hz by a specified amount (-2 or -4 dB) to compensate for the boundary bass boost that occurs when the monitor is placed near a wall or corner. If you don’t want to roll of those lows, set it to 0 dB.

This combination of controls lets you create a linear response for accurate monitoring and enables you to simulate different listening environments, so you don’t have to listen to mixes on your car, consumer computer speakers, and home stereo to check how the music sounds with different systems. Instead, you can adjust the Eris monitors’ response and test your mixes without leaving your studio. No other monitors in this price class offer this degree of control.

Safety Matters
Any loudspeaker is subject to an assortment of environmental and performance problems, and Eris monitors offer protection from most common of these. RF shielding protects against radio frequencies that could be induced into the signal and become audible. (If you’ve ever heard a radio broadcast unexpectedly coming out of a guitar amp, that’s the result of RF interference.

Eris monitors also provide over-temperature protection to avoid heat-related issues, current-output limiting (to prevent damage should there be a short circuit on the speaker terminals), and subsonic protection to filter out extremely low-frequency vibrations that could interfere with the woofer’s performance.

Finally, Eris’ power amplifiers have a soft startup so that you don’t get damaging pops in the speakers when you power them up.

Sound Thinking
By now, it should be clear that Eris-series speakers deliver a lot more than you would expect from a budget-priced studio monitors. As you expect from PreSonus, they use quality components, are well constructed, and deliver professional audio quality. They’re lightweight and compact and look as professional as they sound.

But what really sets them apart from comparably priced systems are user controls that allow you to tailor the speakers’ response to your needs.

Great Monitors for the Price
What is your opinion of this product?
I ran an A/B test with the Eris E8's and Yamaha HS8's. For me, the HS8's had piercing highs that weren't manageable at Unity. The E8's sound flat at Unity. I was leary at first, given that Presonus isn't known for studio monitors, but I am pleased with my purchase. I'm a musician first and an audio engineer out of necessity. With that said, I need my monitors to be flat and convey the truth. At my budget, I was afraid that I wouldn't be able to find anything that would get me close to a truly flat sound, without low/mid/high over compensation. However, the E8's have definitely delivered. The front firing bass ports have dramatically improved the sound of my small studio monitoring environment as well. Rear firing ports + close proximity to a wall x small room = sonic disaster. Stepping up from 5.25's, I can now clearly hear the bass nuances that need to be addressed. Also, the shielding is amazing. I no longer have an issue with crosstalk and computer noises.

What is your opinion of this product?
Great deal over Black Friday. The speakers were at a bargain price , and with the starter package included it was a no brainer purchase. This will be a Christmas gift for my son. (what a nice Dad). I have purchased many Presonus products and I'm sure the quality is there. My only negative comment is that the starter pack did not contain the same cables as listed in the add. Instead of four xlr to trs cables. Two of the cables were xlr to xlr. I just went ahead and purchased two xlr to trs daptors so they will work.
