Key Info
The Eris E66 Active MTM Series Nearfield Monitor from PreSonus delivers an expanded and highly accurate frequency response and a wide stereo field. Its nested Midwoofer-Tweeter-Midwoofer (MTM) 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.
Conventional 2-way designs can cause significant early reflections from their surrounding environment. The E66 overcomes this by positioning a 1.25", silk dome high-frequency driver between two 6.5" midrange drivers. The two smaller woofers work in parallel to partially contain the dispersion of the tweeter, minimizing phase displacement. The result is detailed stereo imaging.
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. This results in the combined signal of both drivers propagating 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.
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.
