The Eris Sub8 is the first subwoofer to join the lauded and best-selling Eris studio monitor line. We called it Eris because it’s been designed from the ground up to be part of the family; it compliments the voicing and frequency response of the modern Eris classics.

    Before going into the details of the review it’s important to point out that these speakers are actually designed as “near-field” monitors, not home-audio loudspeakers. I’ve seen a handful of complaints about lack of bass reponse, hollow sound etc.Near-field monitors are designed to reproduce sound with a *flat* response to give an accurate, faithful reproduction of the original audio without enhancements. And the name implies their intended usage, to be listened “near” to the speaker itself at low-to-medium volume levels, not from 10-20 feet away with room-filling sound.By contrast, “loudspeakers” are used for home audio and they typically have boosted bass and or treble response (low and high frequencies) to make the sound more punchy and colorful, especially since nearly all consumer audio sources come from highly compressed MP3 sources where much of the dynamic range of the original music track has been lost.The PreSonus Eris series are all designed to be professional near-field monitors used for making critical mixes for audio or film/video production, and in that intended usage the Eris 3.5’s shine.The response is definitely flat with a little more low-end punch than I would have expected for a monitor this size. In fact I’m outright surprised how much low-end (bass) comes out of this small-ish pair. The rear-porting coupled with being close to a wall provides ample if not a tad too much bass reinforcement. I think for future design evolution having a front-ported enclosure would most likely make the bass response a bit more accurate, however I’m totally pleased with the output they provide.One thing that sets this pair apart from the competition other than it’s accurate sound reproduction, is that they have both a high and low-end tuning knobs on the back of the primary unit (left side). All others simply have a volume or output level adjustment, but no way to actually TUNE the speakers to the environment. That’s a big plus and normally only found on larger and pricier units.Although these are monitors and not loudspeakers they do provide a ton of physical sound output, far louder than I would have expected for such a small near-field monitor. (Remember, near-fields are designed for up-close low-to-medium volume levels.)I considered several different models at this size and for the money you can’t get or expect a better pair of monitors, they rock! Mine haven’t even broken-in yet (new drivers need a break-in period to maximize their potential) and I’m already in love – it will only get better with time.As long as you clearly understand the difference between what a loudspeaker and a near-field monitor is supposed to do then you’ll be amazed at how good the Eris 3.5’s sound. Get a pair and enjoy!!! I definitely am.

    (this is a review of the PreSonus Eris E3.5 model)Good:- Sound is neutral- Very accurate sound stage- The ‘acoustic tuning’ it’s called allows you to adjust for environment- aux in on front- professional look that isn’t flashy and full of leds trying to call attention to itself.Cons:- Cables you get are pretty mediocre- Cabinet build quality feels cheapA quick background. While I’m no audio engineer and I wouldn’t classify myself as an audiophile I do have several headphones in the $100-$300 range and a headphone amp and dac. I was looking to upgrade my 15 year old set of pc speakers that work but I knew I could get better.Sound wise these are called “Multimedia Studio Monitors” and by that definition these are really accurate. I also primarily have headphones with a flat response curve so these very much sound like headphones in that regard. They do have bass but it’s not going to rock the place. I’m going to skip getting in to details on audio since other reviewers have done a great job already and I agree with all of them. But if you are looking for accurate speakers for a computer just get these and you’ll be happy. I would not recommend them for a television or something where you are trying to fill an entire room with sound.The rest of this review is for people that do buy them and it’s their first pair of “studio monitors”.First off while they seemed to use excellent components for the monitors the cables they give you are pretty mediocre. I included a picture of what’s included (power cable is already plugged in and not pictured). The speaker wire that goes between the two speakers is about 6 feet and almost look like 18 AWG wire. I ended up buying 14 AWG wire but knowing what I know now I’d have just got 16 AWG and it would be a little easier to work with. I then connected them to pc using an 1/8″ to RCA jacks. The cable they give you is around 5 feet and my computer was further away so had to buy a new cable for that. Any of the 1/8″ to RCA should work fine. The power cable is a standard IEC7 non polarized connector and was maybe around 6 feet.Some setup tips. First off the full manual is not included but can be obtained from and searching for eris e3.5 and going to downloads. This explains far more about placement and adjustment than the quick start that’s included or even what I say here. The manual explains the details but the volume on the monitor should be around the 11 o’clock to 12 o’clock position in most situations. Once you set that don’t touch the volume control on monitor, adjust the audio from the source. With the monitors set to 11 o’clock the signal coming from the computer was too hot (too loud). I would have only been able to turn the volume up to 10% and it was really loud. RCA attentuators will reduce the volume by a certain amount just before entering monitors. Oddly amazon doesn’t have them, or they were really overpriced. Search online for “Harrison Labs 12 dB RCA Line Level Attenuator” and it should be in the $30-$40 range as of March 2018. This allowed me to have a greater working range on volume. I now typically listen at around 40% level on computer but occasionally turn it up or lower it. One last thing I bought were  Wellcn 26 Pcs Ferrite Cores – EMI RFI Noise Filter Clip for 3mm/ 5mm/ 7mm/ 9mm/ 13mm Diameter-Black . Place those on the power and RCA cables a couple inches before they connect to monitor. I got some occasional crackling sounds and those removed it. I also put one on the aux cable I use to connect my work laptop to these when working from home. It’s not needed on the speaker cable going between the monitors but also won’t really hurt anything. **See update below on how I’ve changed this**From where you are normally positioned there should be an equilateral triangle between you, the two monitors, and the space between the monitors. Meaning if you’re head is 3 feet from front of monitor they should also be 3 feet apart and then be turned to face you. If done right you won’t see the sides of monitors. You want your ear to be lined up with the small tweeters. Because mine are mounted on a wall a little high I have them tilted down and also on their side, which these monitors support. If you do this make sure to mirror the monitors. Meaning have the tweeters on the outside to get a larger sound stage. Once this is all setup don’t touch the equalizer or “acoustic tuning” as they call it. Just listen to music for a few days to get used to them. There also may be a little bit of break in needed. Only after a few days should you make small adjustments to the acoustic tuning options. It’s preferable to turn down a setting than boost it. If you’ve edited photos you may have noticed trying to boost the brightness on a dark image looks worse than darkening a bright image. Same idea here. So if it sounds to tinny or harsh you want to turn down the highs slightly. This reduces the highs and thus the lows will be more prominent. Initially it sounded tinny but after a couple days it either went away or I got used to it I haven’t had to touch mine.One last thing I’d recommend. Since these are fairly portable, but all my wires are routed around desk I don’t want to undo them if I decide to take monitors with me somewhere. I bought me an extra power cable and then use the 1/8″ to rca cable and speaker cable they give you and put in a small ziplock bag. Now all I have to do is disconnect everything from monitors, grab my ziplock bag of stuff and I’m ready to go.I know that was a lot of information but I hope you found this information helpful and enjoy these.(update: December 2018)So far these have been holding up well and have had no issues. In fact considering buying a second pair to have over by my workbench. Since writing above I changed my setup so now I have a Maker Hart Loop Mixer that I connect my computers and to and then audio goes from there to PreSonus. It lets me adjust levels and I still have some inputs open so I’ve done things like be on a conference call but also have music playing while I’m waiting for them to start. I also got rid of the RCA Line Level Attentuators. May buy more but only -3 or -6db as the loop mixer doesn’t get as loud.

    Stopped working within two days. They sounded great and worked fine up until then.. I went outside for an hour and left them on. When I came back in I heard a rustling noise upstairs. It was the passive monitor. Turn on some music and find the passive monitor doesn’t work period. Mind they were working just fine before I left the room. Unplug it from the from the interface and it still makes the sound. Plug it into my laptop, same issues. This product makes me really question if checking review ratings on amazon products even means anything because a quick google search will show that the issues i’ve posted about are common, and I likely have to ship them back for maintenance or replacement. You’ll barely find evidence of that here in the reviews.
