Our best-selling monitors just got better! Eris® 4.5 BT 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 4.5 BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave and nature of the Eris 4.5 BT'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 4.5 BT 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 acurate 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.
