Eris 4.5 BT - Sound You Can Rely On!

PreSonus' best-selling studio monitors are now even better! The Eris 4.5 BT media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideal for bedroom studios, video production, and high-fidelity gaming setups.

The Eris 4.5 BT reference monitors feature a built-in power of 25 watts per side while still delivering clear, precise sound. The weave and construction of the Eris 4.5 BT's 4.5-inch woofer provide tight, punchy bass you can feel and a clean overall sound. The 1-inch silk-dome tweeter produces refined high frequencies and is designed to radiate sound with a wide dispersion pattern, creating a large optimal listening area. Improved speaker tuning compared to earlier models yields fuller bass and a smoother transition for articulate, precise transient reproduction across the entire frequency range and a less fatiguing listening experience.

A handy front-panel control lets you adjust the amplifier level and the loud, clear headphone amp that is accessible via a front jack. With four input types, including fast, reliable stereo Bluetooth® 5.0 connectivity, you can connect almost any audio source to your Eris 4.5 BT reference monitors. The high- and low-frequency controls let you easily tailor your Eris speaker's frequency response to compensate for room acoustics and achieve the most accurate playback possible.

Need a bit more deep bass? Add an Eris Sub8 BT to build a perfectly tuned 2.1 system that fits almost anywhere.

Absorber Panels

Pronomic ISO stand absorber pads are ideal for placing under studio and nearfield monitors. The foam reduces and damps unwanted resonances and vibrations, noticeably improving your speakers' sonic character. Not only does reduced transmission of structure-borne vibration help optimize sound, but the two-component design of these isolation wedges also contributes. This construction lets you position studio monitors at five different tilt angles to perfectly align them with your listening position.
