PreSonus Eris E44 MTM Dual 4″ Powered Studio Monitor

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.
