Studio-grade monitoring has never been more accessible than with the PreSonus® Eris® 3.5BT media reference monitors, delivering professional audio quality in a beautifully compact design. These monitors feature a 3.5-inch woven-composite woofer paired with a 1-inch silk-dome tweeter, powered by 25 watts per side of Class AB amplification that provides serious low-end punch whilst maintaining crystal-clear, accurate audio reproduction across the entire frequency range.
The Eris 3.5BT excels in versatility with Bluetooth® 5.0 wireless connectivity alongside comprehensive analogue inputs including 1/4" balanced TRS, RCA, and front-panel 1/8" stereo auxiliary connections. An integrated headphone amplifier with front-panel output adds convenience, whilst high- and low-frequency tuning controls allow precise adjustment of the speaker’s response to suit any listening environment or personal preference.
Trusted by audio engineers and producers globally, the Eris series has earned its reputation through improved speaker voicing that delivers richer lows and smoother crossover transitions for articulate transient reproduction. The elegant, compact enclosure with rear-firing bass-reflex port makes these monitors perfect for bedroom studios, video production suites, gaming setups, and anywhere space is at a premium but audio quality cannot be compromised.
