Presonus Eris 66 active monitor

Presonus Eris 66

The Eris E66 delivers an expanded and highly accurate frequency response and the widest stereo field available in its class. 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, smoother frequency response, and an ultra-wide, detailed stereo soundstage. 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/D’Appolito 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.

Features:

• 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
• Balanced XLR, balanced ¼-inch TRS, and unbalanced RCA inputs provide flexibility for seamless integration into any environment
• Acoustic tuning controls help to compensate for room anomalies, providing a consistent frequency response customized for your mix environment
• Continuously variable HF and MF controls (-6 to +6 dB)
• Low-cut filter (flat, 80 Hz, 100 Hz)
