PreSonus’ Eris E44 and E66 MTM Monitors Provide Ultra-Wide Imaging
PreSonus’ new Eris E44 and E66 two-way active MTM studio monitors claim to deliver an expanded frequency range and the widest stereo field in their class, due to their nested Midwoofer-Tweeter-Midwoofer (MTM, also known as “D’Appolito”) design. The result is a more consistent listening experience on- and off-axis.
The E44 and E66 nested MTM configuration incorporates dual Kevlar low/mid drivers (4.5- and 6.5-inch, respectively) operating in parallel and covering the same frequency range so that they acoustically couple. Persons says that this effectively creates a larger woofer to provide a more dynamic output than conventional two-way studio monitors. Nesting a 1.25-inch, silk-dome, high-frequency driver between the two woofers minimizes phase displacement to improved spatial resolution.
By bringing the midrange drivers close together and raising the HF driver, the E44 and E66 are able to perform optimally in both horizontal and vertical orientations. A three-position Acoustic Space switch helps compensate for the boundary bass boost that occurs when the monitor is placed near a wall or corner. High and Mid acoustic tuning controls further help to mitigate room problems. A Low Cutoff filter makes it easy to integrate a subwoofer. Individual balanced XLR and ¼” TRS and unbalanced RCA input connections make hookup quick and easy. Safety features include RF shielding, current-output limiting, over-temperature protection, and subsonic protection.
Eris E44 and E66 studio monitor speakers are expected to be available in the third quarter of 2015 at an anticipated street price of $249.95/speaker and $349.95/speaker, respectively. All the tech specs are here.
