Overview

The PreSonus Eris E44 is a powered studio monitor built around a nested MTM (Midwoofer-Tweeter-Midwoofer) configuration, also known as a D'Appolito design. By placing a 1.25" silk-dome tweeter between two custom 4.5" woven composite low-frequency/midrange drivers, the E44 achieves smoother on- and off-axis frequency response than conventional two-way monitors. This design minimizes vertical phase displacement, which translates to a wider sweet spot and improved spatial resolution — meaning you can move your head without the stereo image collapsing, and multiple people in the room can hear an accurate representation of the mix. The dual woofers also combine to produce bass output that exceeds what a single 4.5" driver could deliver, giving the E44 a fuller, more dynamic low end.

Powering the E44 is a 90W Class A/B bi-amplification system that drives the low-frequency and high-frequency sections independently, resulting in a clean, open sound with minimal intermodulation distortion. The rear panel features continuously variable high-frequency and mid-frequency controls, each sweepable from -6dB to +6dB, allowing you to tailor the monitor's output to compensate for room anomalies like reflective surfaces or corner placement. Connectivity covers all common scenarios with balanced XLR, balanced 1/4" TRS, and unbalanced RCA inputs. The E44's ability to be mounted vertically or horizontally adds further flexibility for different studio configurations. PreSonus rounds out the package with Studio One Prime and the Studio Magic plug-in suite, giving new producers a complete set of tools to start creating immediately.

Key Features

Nested MTM (D’Appolito) design with dual woven composite drivers provides smooth on- and off-axis response with more dynamic output than conventional two-way studio monitor configurations.

MTM (D’Appolito) design minimizes phase displacement and leads to improved spatial resolution and a much wider sweet spot.

Dual 4.5-inch, custom-woven composite LF/midrange drivers produce dynamic, size-defying bass output.

1.25-inch, silk-dome HF driver ensures smooth high-frequency performance that is never fatiguing to the ears.

Includes Studio One Prime and Studio Magic plug-in suite, over $1000 USD worth of music production software.

Unique design supports vertical and horizontal loudspeaker placement to fit into any mix environment.

90W Class A/B bi-amplification for an open, clear sound.

Acoustic tuning controls help to compensate for room anomalies, providing a consistent frequency response customized for your mix environment.

Balanced XLR, balanced ¼-inch TRS, and unbalanced RCA inputs provide flexibility for seamless integration into any environment.

Continuously variable HF and MF controls (-6 to +6 dB) help further fine-tune the sound for the space you’re in.

Pros & Cons

👍 Pros

MTM D'Appolito driver arrangement produces a noticeably wider sweet spot than standard two-way monitors, reducing the need to sit in one exact position
Dual 4.5" woven composite drivers deliver more low-end output and dynamic range than typical single-driver monitors of similar size
Continuously variable HF and MF EQ controls allow precise room correction without needing external processing
Three input types (XLR, TRS, RCA) make the E44 compatible with virtually any audio source
Included Studio One Prime and Studio Magic plug-in suite add significant production software value at no extra cost

👎 Cons

At 90W total bi-amplification, the E44 may not provide enough volume for larger rooms or loud mixing environments
The MTM configuration makes each unit taller and heavier than a comparably rated single-woofer monitor, requiring more desk or stand space
Sold individually rather than as a pair, so the total cost for a stereo setup is double the listed price
No built-in low-frequency rolloff switch is mentioned for desktop or wall-adjacent placement, which can cause bass buildup

Frequently Asked Questions

What does MTM (D'Appolito) design mean on the Eris E44?

MTM stands for Midwoofer-Tweeter-Midwoofer, a configuration where the tweeter is nested between two identical woofers. This D'Appolito arrangement minimizes phase displacement and creates a wider, more consistent sweet spot compared to conventional two-way monitors.

Can the Eris E44 be used both vertically and horizontally?

Yes, the E44 is specifically designed to support both vertical and horizontal placement, making it adaptable to different studio layouts, desk setups, and surround configurations.

What input connections does the Eris E44 accept?

The E44 provides balanced XLR, balanced 1/4" TRS, and unbalanced RCA inputs, so it can connect to professional audio interfaces, consumer electronics, and everything in between.

What acoustic tuning controls are available on the Eris E44?

The rear panel includes continuously variable high-frequency and mid-frequency controls, each adjustable from -6dB to +6dB, allowing you to compensate for room acoustics and personal monitoring preferences.

What software is included with the Eris E44?

Each Eris E44 includes PreSonus Studio One Prime and the Studio Magic plug-in suite, providing over $1,000 worth of music production software out of the box.
