Description
PreSonus Eris-series studio monitors are used worldwide by audio engineers and producers who need to hear every detail of their recordings. Eris 3.5 media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for use as bedroom studio speakers, turntable and record player speakers, video post-production speakers, or high- fidelity audio monitors. With 25 watts per side of onboard power, the Eris 3.5 reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave of the 3.5-inch woofer results in tight bass that you can feel, while 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 the previous first generation design delivers richer lows and a smoother crossover transition for articulate, accurate transient reproduction throughout 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 three types of inputs, it's easy to connect just about any audio source to Eris 3.5 reference monitors. High- and low-frequency controls let you easily adjust the 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? Put some boom in your room with an Eris Sub8 BT to build a perfectly matched 2.1 sound system that fits almost anywhere.

SOLID HOME PRODUCTION MONITOR SPEAKERS! Can't beat them for the price point!
Size: 3.5" Monitor
Color: White
These speakers have been great. I have had them a year now. I use them EVERY DAY for production with FL STUDIO and my CASIO PRIVIA/ and MIDI KEYBOARD with Audio Interface connected to the back of the speakers and NEVER had any issue with them. Installation was super easy, appearance is cool, volume and sound are great. For the price they are actually surprisingly powerful and accurate. If you connect them without the proper wires or connect them incorrectly that would be a reason they would not work. Honestly can't believe how inexpensive they were. They are also super easy to adjust. Great for home production. Don't believe the negative reviews.

Solid purchase for my Roland.
Size: 3.5" Monitor
Color: Black
Crystal clear and perfect for my home setup with my Roland Juno DS88. Really happy with the sound quality and volume. I like that there are 1/4 inputs. They fit perfect on some piano stands as well, nice and compact. No issues with connectivity.

Great for computer speakers or amateur music/video production
Size: 3.5" Monitor
Color: White
When my Creative Pebble 2.0 computer speakers stopped working, I knew I needed a new set of speakers. In years past, I had the Rokit 5 G2 monitors and matching subwoofer for my main video editing computer. But right now I don't have that kind of money to spend, and I'm not currently doing enough paid editing work to justify that kind of investment. I needed speakers that would mostly be used for listening to music, watching video content, and for editing videos occasionally. Enter the PreSonus Eris 3.5, which at just under $100 was at the top end of what I could spend. I almost went with the Ortizan C7, but decided on these instead both for the smooth volume knob adjustment and the PreSonus brand name. They were easy to set up with my MacMini, they look great on my white desk, and there's always the option to get the Eris subwoofer if I want to. I did not need Bluetooth connectivity, just wired RCA or 3.5mm, with the option to do 1/4" later on. Be aware these are not true active monitors, they're basically something between that and computer speakers. The left side has the power cable, the inputs, and the bass/treble adjustments. The right speaker is a passive "satellite" that connects with regular speaker wire. At 25w each, I can't see the point of upgrading the wire to a larger gauge. The tweeters do have a grille covering them which is nice, and the carbon fiber woofers have a smooth concave dustcap. I'm not worried about denting the woofer or tweeter. Now let's talk about sound. These definitely get loud enough for a bedroom or small office. I rarely turn mine up past 50% and at that level it's louder than I normally listen to things. The response is maybe a little heavy on bass/mid-bass, so I turned down the bass knob on the speaker to about 30% and use an EQ program on my computer to slightly boost the mids/highs and roll off the bass. With that, the speakers sound balanced to my ears. If you're using these for consuming entertainment, they certainly fit the bill. If you're mixing your own music/videos as an amateur or low-budget prosumer, then these will probably work if you set the EQ right for your room. I would still recommend checking your mix on a good pair of headphones and also a cheap mono speaker. They look good, they sound good, and have just enough upgrade options to work at the prosumer level. I did not pay extra for the Bluetooth feature as I figured the subwoofer comes with that functionality if I really want it later on. EDIT: I bought a right angled power cable and angled RCA adapters so that I could fit the Left speaker closer to the wall than the factory cables would allow.

Big bang, little buck
Size: 3.5" Monitor
Color: White
These are very nice performing little monitors that are perfect for a small desk setup. They give good representation of a mix and are invaluable when paired with monitors that reveal the lower frequencies. The sound quality is very nice but they, being small, don't throw the bass out like you may want. I purchased their larger counterparts (Eris series) but still find these little desktop monitors very useful and they sound fantastic as PC speakers. Also, I've found, it's good to mix using some "great" speakers and then check it out on speakers that mirror what most people listen on. Overall, very clear, very solid, very easy to setup. For the cash? Most recommendable.

I wasn't expecting a whole lot just because of the price alone, but these are great! Out of the box, they have great low-end definition and everything sounds clear even without additional tuning. Great buy!

Excellent computer speakers

Outstanding for the price. Way better than any computer speakers. Not a ton of bass, but what bass it has is balanced. If you want more, get a sub.

Decent quality, a little boomy

Color: Black
Good build quality. If you listen to podcasts on these though, the response is a tad boomy especially for male hosts. Otherwise, these sound good for the price.
