PreSonus Eris E44 Active MTM Series Nearfield Monitor

Overview of PreSonus Eris E44 Active MTM Series Nearfield Monitor

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.

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.

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.

Features:

• Dual 4.5-inch, 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
• Balanced XLR, balanced ¼-inch TRS, and unbalanced RCA inputs provide flexibility for seamless integration into any environment
• Acoustic tuning controls help to compensate for room anomalies, providing a consistent frequency response customized for your mix environment
