Presonus Eris Frequency

With their smooth, accurate frequency response; powerful amplification with tons of headroom; and acoustic tuning functions that ensure you always get the best sound... it's no wonder that the original Eris®-series studio monitors have been a runaway hit since their introduction. The Eris E7 XT builds on the Eris XT-series adding big, controlled bass in a compact form that will fit into a studio of nearly any size. Deep lows and a wide, more controlled sweet spot (thanks to its EBM waveguide design) mean that our best-selling studio monitors just got even better.
