PreSonus-Eris E66 Studio Monitor

The Eris® E66 studio monitor delivers an expanded, highly accurate frequency response and the widest stereo field available in its class. 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 two-way speaker designs can cause significant early reflections from their surrounding environment. The Eris E66 studio monitor overcomes this by positioning a 1.25-inch, silk dome, high-frequency driver between two 6.5-inch midrange drivers that cover the same frequency range. The combined signal of the two relatively small drivers propagates forward like a single waveform, behaving like a single, larger driver. This mutual coupling provides a highly dynamic output in a compact footprint resulting in size-defying bass reproduction. At the same time, the two smaller woofers work in parallel to partially contain the dispersion of the tweeter, minimizing phase displacement. The result is incredibly detailed stereo imaging. Like all Eris studio monitors, the E66 offers flexible connectivity and extensive acoustic tuning controls. The three-position Acoustic Space switch plus High and Mid controls help to mitigate room anomalies. A Low Cutoff filter makes it easy to integrate a Temblor® subwoofer into your monitor setup. Features Nested MTM (D'Appolito) design with dual woven composite drivers provides smooth on- and off-axis response with more dynamic output than conventional two-way studio monitor configurations MTM (D'Appolito) design minimizes phase displacement and leads to improved spatial resolution and a much wider sweet spot Dual 6.5-inch, custom-woven Kevlar LF/midrange drivers produce dynamic, size-defying bass output 1.25-inch, silk-dome HF driver ensures smooth high-frequency performance that is never fatiguing to the ears 140W Class A/B bi-amplification for an open, clear, and less fatiguing listening experience
