PreSonus Eris E5 Two-Way Active 5.25" Studio Monitor (Single)

The PreSonus Eris E5 Two-Way Active 5.25" Studio Monitor delivers accurate response with tight bass and clear upper end. The Kevlar low-frequency transducers, low-mass silk-dome tweeters and responsive Class-AB amplification combine with acoustic-adjustment controls to create a versatile and adaptable listening system.

The E5 sports a 5.25-inch, Kevlar low-frequency driver, with a 45W, Class AB amplifier; and a 1-inch (25 mm), silk-dome tweeter powered by a 35W. It can crank out a clean 102 dB SPL, peak. Frequency response is rated at 64 Hz to 22 kHz. For a studio monitor in its size and price class, the E5s are truly impressive.

All Eris speakers have front-ported enclosures made of vinyl-laminated, medium-density fiberboard (MDF). You’ll have no problem hooking your Eris speakers up with virtually any line-level source. Featuring 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.

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. With versatility 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 E5/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 E5 or 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. 

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.
