The PreSonus Eris E66 Active MTM Nearfield Studio Monitor delivers an accurate response, expanded frequency range, and the widest stereo field available. Thanks to the nested MTM design, the E66 provides an ultra-wide, detailed stereo soundstage and a more consistent listening experience on- and off- axis.
The MTM’s innovative design has a few benefits. The usual 2-way monitor design causes significant early reflections from its 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. This results in an incredibly detailed stereo image.
The Two midrange drivers cover the same frequency range. Their acoustic centres 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 set up of drivers makes them behave like one single, large driver.
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 listener’s ear. In conjunction with the MTM configuration, this works to create a transparent, cohesive sound.
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. So, like all Eris speakers, the E66 will let you position your speaker the way that works best for you.
