Are you serious about creating music? These monitor speakers are a must-have! They'll reveal every flaw in your tracks and mixes. With accurate response, tight bass, and clear upper end, they deliver the truth.
Cheap computer and home-stereo speakers hide flaws, while low-cost studio monitors may not be true to your final production. But PreSonus Eris-series active studio monitors are different.
Featuring well-designed Kevlar low frequency transducers, low-mass silk-dome tweeters, responsive Class AB amplification, and professional acoustic-adjustment controls, they're the real deal.
PreSonus products are known for quality components, solid construction, and professional audio. They're lightweight, compact, and look as good as they sound. What sets them apart? Pro features like user controls to tailor the response. And they're ultra-affordable!
The Acoustic Space ControlAll Eris speakers have three EQ controls in the Acoustic Tuning section: High, Mid, and Low Cutoff. Fine-tune the monitors or approximate different speaker sounds. The Low control is great with a subwoofer.
There's also a three-position Acoustic Space switch. It controls a filter to cut low frequencies near walls or corners. Set it to 0 dB if you don't want to cut.
This combo of controls lets you create a linear response and simulate different listening environments. Test your mixes right in your studio!
Eris E4.5Tight on space? The ultra-compact Eris E4.5 is perfect! Despite its small size, it offers professional audio quality. It has a 4.5-inch Kevlar low-frequency driver, a 1-inch silk-dome tweeter with grille, and Class AB amplification. Each speaker has a 25W Class AB amplifier. It ranges from 70 Hz to 20 kHz and fits easily into any studio space at 6.42 x 9.45 x 7.09 inches (163 x 241 x 180 mm).
