PreSonus Eris E66 MTM Active Studio Monitor
Description
The Eris E66 delivers an expanded and highly accurate frequency response. 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 and a smoother frequency response.
Features:
Conventional 2-way designs can cause significant early reflections from their surrounding environment. The E66 overcomes this by positioning a 1.25-inch, silk dome high-frequency driver between two 6.5-inch midrange drivers. The two smaller woofers work in parallel to partially contain the dispersion of the tweeter, minimizing phase displacement.
Seeing Double.
The E66 features two midrange drivers that cover the same frequency range. 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. This makes the comparatively small midrange drivers in the E66 behave like a single, larger driver. This mutual coupling provides a highly dynamic output in a compact footprint.
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 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. This makes the E66 ideal as a centre channel speaker for Dolby Atmos mixing.
Transparent and Cohesive Sound.
The E66 utilizes 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 listeners ear. In conjunction with the MTM configuration, this works to create a transparent, cohesive sound.
Horizontal or Vertical. Its 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 E66 is able to perform optimally in both orientations. The E66 lets you position your speaker the way that works best for you.
Making Connections
With three different types of audio inputs, its 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 E66 provides balanced XLR, balanced TRS, and unbalanced RCA line-level inputs. With this selection, you'll have no problem hooking your Eris speaker up with virtually any line-level source.
