PreSonus Eris E66 Studio Monitor

The PreSonus Eris E66 applies the Midwoofer-Tweeter-Midwoofer design at a larger scale, seating a 1.25-inch silk-dome tweeter between two 6.5-inch midrange drivers. The paired woofers propagate as one waveform for powerful, size-defying low end and one of the widest stereo fields in its class.

Running the two woofers in parallel partially contains the tweeter's dispersion and minimizes phase displacement, producing detailed imaging with fewer early reflections. A three-position Acoustic Space switch plus High and Mid controls address room anomalies, and a Low Cutoff filter integrates a subwoofer cleanly. Sold individually.
