The new PreSonus Eris E44 Studio Monitors are very versatile, 2-way active studio monitors with Midwoofer-Tweeter-Midwoofer design, and, for extra versatility, they can be places horizontally or vertically. Superb value, and ideal for professional results, thank to its hi-performance specs.

Ultra-wide, detailed stereo soundstage. The Eris E44 delivers an expanded and highly accurate frequency response and the widest stereo field available in its class. Its nested Midwoofer-Tweeter-Midwoofer (MTM, also known as “D’Appolito”) configuration offers improved off-axis response and spatial resolution. The result is a more consistent listening experience, smoother frequency response, and an ultra-wide, detailed stereo soundstage.

Smooth and Wide - that's right, the new PreSonus Eris E44: MTM design delivers the widest sweet spot in its class, providing you with a consistent listening experience, all the time.

Sound waves radiating from the two components in a conventional speaker design can interfere with one another, creating peaks at some frequencies and dips at others, and these will vary depending on where the listener is relative to the speaker. In an MTM/D’Appolito configuration, component interference and the sonic inconsistencies that go with it are minimized. This affords listeners an ultra-wide sweet spot and a more consistent listening experience on- and off-axis.

Transparent and cohesive sound.

The E44 utilizes a pair of 4.5-inch, custom-woven, Kevlar low-frequency drivers. This provides a more constant dispersion pattern throughout the frequency range, resulting in less time-smeared audio and cleaner overall sound. The weave and nature of the dual Kevlar woofers also helps break up reflected energy, so fewer delayed reflections reach the listener’s ear. In conjunction with the MTM/D’Appolito configuration, this helps create a transparent, cohesive sound.

Horizontal or vertical—it’s up to you.

Many MTM configurations must be arrayed vertically, rather than horizontally, because vertical placement provides a clear, interference-free midrange and treble reproduction to either side, expanding the sweet spot. By bringing the midrange drivers closer together and raising the high-frequency driver, the E44 and E66 are able to perform optimally in both orientations. So, like all Eris speakers, the E44 and E66 let you position your speaker the way that works best for you.

You’re in control.

Today’s music producers deal with a wide variety of musical genres and often work in more than one location. That’s why Eris-series studio monitors offer extensive acoustic tuning controls. The three-position Acoustic Space switch helps to compensate for the boundary bass boost that can occur when a monitor is placed in a corner or near a wall. High and Mid controls help to further mitigate room anomalies. A Low Cutoff filter makes it easy to integrate a Temblor® subwoofer into your monitor setup.Accuracy defined.

Like all PreSonus® studio monitors, the Eris E44 offers consistent, accurate listening and extensive user controls. The ultra-wide stereo image afforded by its MTM/D’Appolito design makes it an ideal solution for anyone who requires best-in-class spatial resolution.
