Presonus Eris E4.5 Studio Monitor ( Pair )

Easy-to-use controls.

A speaker’s response is affected by where you place it and the acoustics of your space. That’s why Eris E4.5 active media reference monitors offer controls to adjust the high- and low-frequency content, ensuring that your speakers always sound their best. A convenient front-panel volume knob sets both the speaker level and the integrated headphone amplifier’s level.
