OUR PART # ERIS-E44
The PreSonus Eris E44 is an active MTM (midwoofer-tweeter-midwoofer) nearfield monitor that offers improved on/off-axis response and spatial resolution, as well as expanded and highly accurate frequency response with the widest stereo field available in their class. The result is a more consistent listening experience, smoother frequency response, and an ultra-wide, detailed stereo soundstage.
Conventional 2-way designs can cause significant early reflections from their surrounding environment, and the E44 overcomes this by positioning a 1.25-inch, silk dome high-frequency driver between two 4.5-inch midrange drivers. The two smaller woofers work in parallel to partially contain the dispersion of the tweeter, minimizing phase displacement.
The E44’s two midrange drivers cover the same frequency range, and the drivers are placed so that their acoustic centers are less than one wavelength apart for any of the frequencies they reproduce. As a result, the combined signal of both drivers propagates forward like a single waveform and makes the comparatively small midrange drivers in the E44 behave like a single, larger driver. This mutual coupling provides a highly dynamic output in a compact footprint.
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 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 custom-woven Kevlar® low-frequency drivers to provide 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 configuration, this works to create a transparent, cohesive sound.
Horizontal or Vertical
Many MTM configurations must be arrayed vertically, 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 is able to perform optimally in both orientations. So, the E44 lets you position your speaker the way that works best for you.
Eris-series studio monitors offer extensive acoustic tuning controls for producers that deal with a wide variety of genres or work in more than one location. 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.
With three different types of audio inputs, it’s easy to feed audio to your Eris monitors from a mixer, an interface, a media player, or almost any other line-level source. The Eris E44 provides balanced XLR, balanced ¼” TRS, and unbalanced RCA line-level inputs. With this selection, you’ll have no problem hooking your Eris speakers up with virtually any line-level source.
