At 50 watts, PreSonus' Eris 4.5BT studio monitors are a prime option for producers, gamers, and audiophiles working in condensed spaces. Each speaker is fit with a 4.5-inch transducer and 1-inch silk-dome tweeter, generating crystal-clear, adjustable playback on all ends. Additionally, versatile connectivity options and an ergonomic form factor allow Eris 4.5BT studio monitors to fit into nearly any pre-existing setup with little to no intrusion. Onboard Bluetooth connectivity facilitates seamless mobile device and computer connections, making these speakers a great option for beginner playback setups. Topped off with a vinyl-laminated, medium-density fiberboard construction, Eris 4.5BT studio monitors are equipped to outfit your studio space with years of unparalleled audio performance.

Rig-ready studio connectivity

Ask any Music Experience producer: when it comes to home-based workstations, no studio is the same. The Eris 4.5BT eludes this quandary: its rear panel features a pair of 1/4-inch balanced TRS outputs and standard L/R RCA jacks, granting multiple connectivity options to accommodate setups at any level. Likewise, onboard Bluetooth compatibility makes the Eris 4.5BT a formidable audio playback speaker, perfect for small-scale music systems, gaming rigs, and mobile production spaces. There's no need to worry about power, either — a 50W output guarantees immersive audio in any small-scale studio setting.

Tune into the perfect output

Keeping a balanced audio output is crucial when perfecting your mix. Courtesy of the b rear-panel acoustic tuning knobs, you'll have ample control over the output of your higher and lower frequencies, allowing you to hone in on an output best suited to your environment.

What PreSonus Says...

Our best selling studio monitors just got better! Eris® 4.5BT 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 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.
