The PreSonus Eris E66 Active MTM Near Field Monitors deliver accurate response, expanded frequency range, and the widest stereo field available in their class. Thanks to the nested MTM design, the E66 provide an ultra-wide, detailed stereo soundstage and a more consistent listening experience on- and off- axis.

The benefits of MTM design
Sound waves radiating from the high- and lowfrequency drivers in a conventional design can create an inconsistent off-axis response, coupling to create peaks at some frequencies while cancelling out others, and narrowing the stereo image. By centering a large silk dome tweeter between two smaller woofers that cover the same frequency range, the E66 reduce component interference improving off-axis response and spatial resolution. The result is a more consistent listening experience, smoother frequency response, and an ultrawide, detailed stereo sound stage.

Combined with Kevlar LF transducers
In addition to its clean sound and punchy bass, the weave and nature of the Kevlar design in the dual Eris E66 woofers also works to break up any reflected energyso fewer delayed reflections reach the listeners ear, resulting in a less colored, more cohesive sound. These dual woofers operate in parallel within the same frequency range, acting to minimize phase displacement to afford a much wider sweet spot, improved spatial resolution, and optimal stereo imaging.
