Presonus Eris E4.5 pair

The PreSonus Eris E4.5 is a two-way active studio monitor. The smallest of the range, it has a 4.5" Kevlar woofer and a 1" silk dome tweeter, both powered by 25 Watt amplifier.

The Eris E4.5 has a frequency response of 70Hz-20kHz and a max SPL of 100dB so can deal with a wide range of material. There is also a front-firing bass-reflex port for reinforced low-end response.

The rear of the Eris E4.5 features input gain control, as well as room adjustment controls, including a mid and high +/- 6dB cut/boost, LPF with 80Hz or 100Hz cut-off settings and an 'acoustic' space attenuator control for accommodating different distances between the listening spot and the rear wall in your studio.

The PreSonus Eris E4.5 inputs via 1/4" jack and RCA.

  • 4.5" Kevlar low-frequency transducer
  • 1" ultra-low-mass, silk-dome, high-frequency transducer
