Eris E44: MTM design delivers the widest sweet spot in its class.

The Eris E44 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 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.

The E44 utilizes a pair of 4.5-inch, 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 listeners ear. In conjunction with the MTM/DAppolito configuration, this helps create a transparent, cohesive sound.

FEATURES

Components and construction
- Dual 4.5-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 1/4-inch TRS, and unbalanced RCA inputs provide flexibility for seamless integration into any environment

User controls
- 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)
- Acoustic Space settings (Flat, -2 dB, -4 dB) compensates for room placement

Power and safety
- 90W/140W Class A/B bi-amplification for an open, clear sound
- RF interference, output-current limiting, over-temperature, and subsonic filter protection
- Amplifier "soft start" feature eliminates popping on power-up
- Internal power supply with IEC connector
