Eris E44 *

Product Details

  • 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 4.5-inch, custom-woven composite 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
  • 90W Class A/B bi-amplification for an open, clear sound, and less fatiguing listening experience

Eris® E44 Active MTM (D’Appolito) monitors deliver smooth on- and off-axis response with more dynamic output than conventional two-way studio monitor configurations, thanks to their MTM (midwoofer-tweeter-midwoofer) design, which features a 1.25-inch silk dome high-frequency driver nested between two 4.5-inch woven composite low-frequency drivers. The nested MTM configuration facilitates both vertical and horizontal loudspeaker placement while providing improved spatial resolution with a much wider sweet spot than conventional designs. The weave and nature of the dual woven composite woofers helps break up reflected energy, so fewer delayed reflections reach the listener’s 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 provide optimal stereo imaging.
