Rig-ready studio connectivity

Ask any Sweetwater producer: when it comes to home-based workstations, no studio is the same. The Eris 3.5BT 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 3.5BT 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 3.5BT'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 3.5BT 3.5-inch Powered Bluetooth Studio Monitors Features:

  • Bluetooth-capable studio speakers for audio playback and mix monitoring
  • 3.5-inch woven composite LF transducer and 1-inch silk-dome tweeter keep your output clear and authentic
  • 50-watt performance delivers more than enough power for any desktop studio situation

Perfect for simple home studio

Just purchased an FM3 and was looking for an inexpensive solution for listening in stereo. These have been perfect as a first studio monitor purchase and for the size the tones from my FM3 have been better than expected, not lacking any bass and perfect volume for quiet home use. I have a baby sleeping in an adjacent room and am able to use these without waking her. As a first set of studio monitors these have exceeded my expectations and enabled me avoid using headphones and still enjoy stereo effects without having to worry about volume.

Great speakers for the money!

Easy to install, nice, bright sound, and will mesh in with the subwoofer just fine!!

Presonus Eris 3.5 Studio Monitors

These Speakers served me well for the first Year.Suddenly features either started only working Sometimes or started to Not Work AT All...the auxillary Jack on the front quit working after the first year,so I reverted to the RCA jacks...The RCA jacks workred with minimal output and was really distorted (yes,the Input source was a Balanced,non amplified signal)....so I resorted to Blutooth ONLY as the input...yesterday (Dec 10,2023) the bluetooth Decided it was going to sound Like CB squelch from the 1970's....Tried all the reset methods on the speakers AND the devices that were used through the speakers,to no avail....ALL SQUELCH , ALL THE TIME....
So,I came to Sweetwater to check warranty availability ...Low and Behold,the speakers are now 4 months past the Sweetwater Warranty....so No Help here...
Anyone want to buy some Passive,Unwarranted 3.5 inch speakers???
Here are some stock photos showing the various input jacks,etc.

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.
