The PreSonus Eris E8 XT Two-Way Active 8" Studio Monitor offers the same robust connectivity options with an updated driver combo and a larger ported enclosure. The Hugh Sarvis designed EBM waveguide delivers a wider and more controlled sweet spot, ideal for group listening and collaboration. The E8 XT utilizes 140W Class-AB bi-amplification to power the 8" woven composite woofer and 1.25" ultra-low-mass, silk-dome high-frequency driver, which combine to deliver up to 105 dB of continuous SPL.
