PreSonus Eris E44 High-Definition MTM Dual 4″ Powered Studio Monitor (Single)

Ultra-wide, detailed stereo soundstage
The Eris® E44 studio monitor delivers an expanded, 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.

Consistent listening
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 Eris E44 studio monitor utilizes a pair of 4.5-inch, woven composite, 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 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 speaker 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, Eris E44 studio monitors are able to perform optimally in both orientations, letting 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.
