The compact Presonus Eris 4.5 monitors were created to provide consumers, audio hobbyists and professionals alike with a high-quality solution for their desktop media production. Ideally your nearfield monitoring should be as transparent as possible, providing a balanced, representation of your mix. Too much or too little of particular frequencies can give you the wrong idea how your mix is going to translate to other speaker systems like a car, mobile device, home stereo or even another studio.  You need monitors that accurately reflect your mix so you have a better idea of how it will sound to everyone else.

While each cabinet features a one-inch ultralite silk-dome tweeter and long-throw Kevlar low frequency woofer, Presonus conveniently combines your inputs, power and a high-current 50W Class AB stereo amplifier into one cabinet. Simply connect speaker wire to the other cabinet for stereo operation and unified control of both monitors from a single side. No more shuttling back and forth between monitors to match settings.

The Eris 4.5's are a great and affordable way to get the "real story" from your mix. They feature a High and Mid EQ, low frequency cut-off (so you can add separate subwoofers to handle the lower end) and an acoustic space selector to match the bass output to monitor position (in corners, for example, on each side of a computer screen or out in the room on stands). This way, they not only keep the sound accurate, they're customized to your room.
