3.5-Inch Media Reference Monitors With® Bluetooth Wireless Technology Our best selling studio monitors just got better! Eris® 3.5BT media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for bedroom studios, video production, and high-fidelity gaming setups.

With 25 watts per side of onboard power, the Eris 3.5BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave and nature of the Eris 3.5BT's 3.5-inch woofer result in tight bass that you can feel, as well as cleaner overall sound. The one-inch silk-dome tweeter produces refined high-frequencies and is designed to radiate sound with a wide pattern, creating a large optimal listening area. Improved speaker voicing over previous designs delivers richer lows and a smoother crossover transition for articulate, accurate transient reproduction through the frequency range and a less-fatiguing listening experience.

A convenient front-panel knob sets the level of both the power amp and the loud, clear headphone amplifier, with its front-panel jack. With four types of inputs, including fast, reliable, stereo Bluetooth® 5.0 connectivity, it's easy to connect just about any audio source to your Eris 3.5BT reference monitors. High- and low-frequency controls let you easily adjust your Eris speaker's frequency response to compensate for the acoustics of your space and create the most accurate sonic reproduction possible.

Need a little more low end? Add an Eris Sub8 BT to build a perfectly matched 2.1 sound system that fits almost anywhere.

You also get a convenient (and loud!) front-panel, ⅛-inch stereo headphone jack; connecting headphones mutes the speakers.

Built To Match Your Room.

Unlike other home audio speakers that hype the bass at the expense of other frequencies, Eris® speakers provide an even response throughout the frequency range, from bass to treble. This means you’ll hear your favorite music exactly as artists and engineers intend it to be heard. High and Low Acoustic Tuning controls let you dial in the Eris 3.5 BTs precisely to your environment to further ensure the best sound possible.

Like all PreSonus media reference monitors, the Eris® 3.5 BT offers consistent, accurate listening. Their stylish design makes them a welcome addition to living rooms, compact home theater setups, and gaming rigs, and their smooth and even frequency response ensures that your music — and everyone else’s — will sound incredible.
