The PreSonus Eris® E44 Active MTM (D’Appolito) monitor delivers a smooth on- and off-axis response with more dynamic output than other conventional two-way studio monitor configurations. All thanks to Eris® E44’s 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 vastly improved spatial resolution with a much wider sweet spot than conventional designs. The weave and nature of the Eris® E44’s dual woven composite woofers help to break up reflected energy so that fewer delayed reflections reach your ears during listening, resulting in a less coloured and more cohesive sound. The Eris® E44’s dual woofers operate in parallel within the same frequency range, acting to minimize phase displacement to provide optimal stereo imaging.
