Formidable 50W Bluetooth Audio in a Compact Shell

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 Sweetwater 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 Eris 4.5BT's 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.

PreSonus Eris 4.5BT 4.5-inch Powered Bluetooth Studio Monitors Features:

  • Bluetooth-capable studio speakers for audio playback and mix monitoring
  • 4.5-inch woven composite LF transducer and 1-inch silk-dome tweeter keep your output clear and authentic

Rated 4/5

Was very pleasantly surprised

5 stars as far as value for the money. I wanted something better in my practice room without spending $. Surprised at how loud these can get and the overall sound quality. Bass response is better than I expected. Would I buy them again? Absolutely.
Music background: playing bas for over 50 years.
Rated 3/5

They work great, but need longer included cables

They work fine and bluetooth is a great added features, but all of the included cables are way to short for a reasonable set up. I think they are six feet. Why even include cables that short when most people need at least 10.
Rated 2.5/5

Same as reviewer above - lasted 5 years, then developed popping

These were great until they were not. I had the same experience as one of the other reviewers. They I had them for about 5 years with modest use until they developed a quiet rhythmic popping which happened even when no signal was plugged into them. Sounds like a capacitor in some RC circuit failing. Out of warranty by now unfortunately.
Rated 2/5

Lasted three years

These speakers lasted about three years before developing a rhythmic popping. And the bluetooth stopped working entirely. They still pass a signal and sound good, if you can get past the rhythmic popping noise. I contacted PreSonus support, and they ran me through some troubleshooting, but ultimately said I'm out of luck because the warranty is expired. They went so far to say that they would not under any circumstances provide repairs or even schematics. So basically these are just disposable speakers. I won't be buying PreSonus again. FWIW, the similar M-Audio speakers I had previously lasted twice as long before they died.

Sweetwater and PreSonus go way back, and that makes a lot of sense. Like Sweetwater, PreSonus is largely staffed by active musicians, songwriters, live sound techs, and engineers, and like Sweetwater, their culture shows up in everything they do. Early on, PreSonus broke ground by offering super-affordable audio interfaces that brought quality recording to home studio engineers everywhere. In the following years, we've been with them as they introduced a powerful, artist-friendly DAW, groundbreaking digital mixers, and more - all products we at Sweetwater use ourselves. One thing that's never changed, even as PreSonus has branched out into new territory, is that they've always done everything possible to provide you with the best value, and we're proud to stand by their products.
