PRESONUS Eris E66 140W 2-way with Dual 6.5" LF/MF Drivers and 1.25" HF Driver Studio Monitor

PreSonus’ new Eris E44 and E66 two-way active MTM studio monitors deliver an expanded frequency range and the widest stereo field in their class, which is partly due to the 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 has been designed around the 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. 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 and a wide sweet spot.

Like all Eris speakers, the E44 and E66 provide the tools and flexibility needed to suit any mixing environment. 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.
