Details

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. Thanks to well designed Kevlar low frequency transducers, low mass silk dome tweeters, responsive Class AB amplification, and professional acoustic-adjustment controls, Eris delivers the goods.

Yet Eris series speakers are ultra affordable, making them a terrific value. And with two models, you can easily find the Eris monitor that best suits your studio needs.

If space is at a premium, or if you want the ultimate in portability, consider the compact Eris E5, which takes up just 7 x 10.24 x 7.68 inches (178 x 260 x 195 mm) and weighs in at just 10.2 lbs (4.63 kg). You can shoehorn this little beauty into almost any studio space.

The E5 sports a 5.25-inch, Kevlar low-frequency driver, mated with a 45W, Class AB amplifier; and a 1-inch (25 mm), silk dome tweeter powered by a 35W, Class AB amplifier. It can crank out a clean 102 dB SPL, peak. Frequency response is rated at 53 Hz to 22 kHz. For a studio monitor in its size and price class, that’s impressive.

All Eris speakers have front-ported enclosures made of vinyl-laminated, medium density fiberboard (MDF).

Gazintas
Both Eris models provide balanced XLR, balanced ¼” 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, ¼” TS outputs, simply use a ¼”-to-RCA adapter or adapter cable.)

The Eris E5 provides three EQ controls in its Acoustic Tuning section: High, Mid, and Low Cut-off. 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 E5 with a subwoofer.

The Eris Acoustic Tuning controls let you customize the speaker’s sound with EQ. You get high, mid, and low frequency bands.

The High control is a high frequency shelving filter that boosts or cuts all frequencies above 4.5 kHz by as much as ±6 dB. Use this control to fine-tune the reproduction of high frequencies, depending on your room's acoustic characteristics.

In general, setting the High control to 0 (no boost or cut) will produce the best results. However, if the sound is generally too bright or shrill, try turning this control down below 0; if the sound is too dull and lifeless, try turning it up above 0. (In either case, check your mixer settings to see if anything’s amiss.)

Keep in mind that settings above 0 will also emphasize any high frequency noise in the signal. It's always better to cut than to boost, if possible, and it's best to use the least cut or boost needed to get the job done.

The Mid control is a mid-frequency peak filter that boosts or cuts frequencies centered on 1 kHz and extending about one octave above and below that frequency. Again, setting this control to 0 will generally produce the best results.

If you want to emulate a car stereo, try turning the Mid control below 0 to approximate the common "smiley face" EQ curve. To emulate a cheap portable radio, try turning it up above 0. Try not to boost much, since this can add noise to the signal.

The Low Cut-off control rolls off the low frequencies below the specified frequency (selectable, 80 or 100 Hz) at a slope of -12 dB/octave. Engage this control if you are using a subwoofer in conjunction with the Eris E5/E8 monitors, and set it to the same frequency as the crossover to the subwoofer. If you're not using a subwoofer, set the control to Flat.

If you want to emulate a cheap radio, engage the Low Cut-off at 80 or 100 Hz while boosting the Mid control.

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.

When a monitor is placed close to a wall, or in a corner, the low frequencies tend to be emphasized more than if the monitor is far from any room boundary; this effect is called "boundary bass boost." It is most pronounced if the monitor is in a corner and less pronounced, but present, if the monitor is near one wall. The effect is greater with rear-ported speakers than it is with front-ported speakers like the Eris, but it’s still a consideration.

To compensate for this bass boost, the Eris E5 provides an Acoustic Space switch that cuts all frequencies below 800 Hz by a fixed amount. With this feature, you can control the bass response relative to the wall proximity of your speakers.

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 start-up” 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 Presonus apart from comparably priced systems are user controls that allow you to tailor the speakers’ response to your needs.
