Presonus Eris 4.5BT 2nd Gen

With 25 watts per side of onboard power, the Eris 4.5BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave and nature of the Eris 4.5BT's 4.5-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 4.5BT 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.
