Introducing the Presonus Eris 4.5 BT Media Reference Monitors – an evolution of our best-sellers, now refined for unparalleled performance. Crafted for bedroom studios, video production, and immersive gaming setups, these monitors seamlessly combine studio-quality audio with a sleek, space-saving design.

Empowered by 25 watts per side onboard power, the Eris 4.5 BT ensures robust audio delivery without compromising clarity. The 4.5-inch woofer's intricately woven construction results in impactful bass and a cleaner sonic landscape. The silk-dome tweeter, spanning one inch, produces refined high frequencies, radiating sound expansively for a generous listening sweet spot. Enhanced speaker voicing unveils richer lows and a smoother crossover, facilitating precise transient reproduction across frequencies, offering an enriching and fatigue-free auditory journey.

An intuitive front-panel knob administers both the power amp and the potent headphone amplifier, complete with a front-jack port. Embrace versatile connectivity with four input options, including seamless Bluetooth 5.0 integration. Custom-tailor your audio output using high- and low-frequency controls, adapting the Eris 4.5 BT's response to your acoustic environment, achieving uncompromised sonic accuracy. Elevate your auditory experience with the all-new Eris 4.5 BT – the epitome of refined sound, elegantly packaged.

Key Features:

  • Match Your Environment - In contrast to typical home audio speakers that prioritize booming bass over other tones, Eris speakers deliver a uniform response across all frequencies, spanning from low-end bass to high-end treble. This guarantees an auditory encounter faithful to the artists' and engineers' original vision. Refine your listening experience with precision using the High and Low Acoustic Tuning controls, customizing your Eris 4.5 BTs to your surroundings for optimal sound quality.
  • Expressive Performance - As a part of the PreSonus reference monitor range, the Eris 4.5 BT guarantees unwavering and precise listening. Their sleek design seamlessly complements living rooms, compact home theatres, and gaming setups. The seamless and uniform frequency response guarantees an exceptional auditory experience for your music, as well as for anyone else's, amplifying the incredible sound quality all around.
