Description

The single best subwoofer you can get to put a little boom in your room, 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 The surprisingly loud 100-Watt Eris Sub8 drops down to a molar-rattling 30Hz, allowing you to both rock harder and produce better mixes, as you’ll be hearing an accurate representation of your work. Thanks to robust configuration and I/O, you’ll be able to tailor your Eris Sub8 configuration exactly to your mixing and listening needs. You can connect your existing monitors via ¼” TRS or RCA, set the input level to your liking, and even invert the polarity. Most importantly, you get a High Pass Filter and a Low Pass Crossover control that ensures your Sub8 starts working at the precise low-frequency point where your main monitors stop working. This makes sure you avoid the flubbery, smudged, low-end mess that one hears in redundant, duplicate, redundant bass reproduction that occurs without a crossover.

  • The Presonus Eris Sub 8 (8" Subwoofer) - Once properly set up, it can rock...
1. To begin with, right off the bat - most of you will be quite surprised at the small size of this powered subwoofer. I have a few 8" Powered subwoofers - those being the diminutive (or so I thought) Edifier T5, along with the larger (for an 8" powered subwoofer) Mackie CR-X Series, 8-Inch, 200 watt model. The Eris Sub 8 is virtually half the size of the Mackie and weighs half as much also. I was not prepared for this, but after connecting and setting up the Presonus, my mind was instantly changed for the better. My main two reasons for picking up the Eris Sub 8 was that it would have to be placed under a desk (my system is located on a desktop, near-field scenario), and its size would have to be smaller than the competition. You need to have the proper leg and knee room under the desk, and the Eris Sub 8 gives you that for sure. 2. As far as 8" subwoofers go, I found that the Mackie (whose link is below for your perusal and costs exactly the same price as the Presonus Eris Sub 8) is fairly powerful as far as 8" powered subwoofers are concerned. The size, the heft, the low frequency response, and the overall weight, put it in a league of its own, and I certainly won't be selling mine. The only reason I’m temporarily putting it back in the box is that for the time being, I needed something smaller - thus the acquisition of the Eris Sub 8. For the price, the Mackie unit does incorporate a few additional features, to include a desktop volume control and bass dial (unique and quite convenient), and more power, which can make a difference (especially in larger rooms). As an aside, for informational purposes, the Mackie subwoofer can be found here on Amazon (just copy and paste): https://www.amazon.com/Mackie-CR-Studio-Subwoofer-CR8S-XBT/dp/B083N6Q72Z/ref=sr_1_22?crid=2K6L7QJ72UZE5&keywords=mackie%2Bpowered%2Bsubwoofers&qid=1684872462&sprefix=mackie%2Bpowere%2Bsubwoofers%2Caps%2C100&sr=8-22&ufe=app_do%3Aamzn1.fos.18ed3cb5-28d5-4975-8bc7-93deae8f9840&th=1 3. Getting back to the Presonus, after first connecting everything (setting up the cross-over frequency - I choose around 70 Hz - to cross over to my KEF 150’s), and leaving the gain knob in the 12 o'clock position (where it was set right out of the box), connecting my TRS balanced cables, etc., I was shocked to discover that the default 12 o'clock gain position for an under the desktop subwoofer environment was entirely too much and caused the subwoofer to seemingly bottom out (distort). I first observed this by playing A classical music symphony written by Saint Saens - that being his wonderful (powerful) Organ Symphony 3, and having left the gain at the 12 o'clock position, it bottomed out quickly when the 32 Hz organ notes hit. After careful experimentation, I adjusted the gain setting to around the 7 o'clock position (which is low, I know), where it turned out to be ideal for how I was using it (under the desk), and everything balanced out perfectly. 5. Having a subwoofer(s) that allows for both input and output RCA jacks, along with a frequency cut-off dial, makes it an exceptionally convenient audio product. To also have balanced inputs/outputs (both the Presonus and Mackie have TRS inputs/outputs also) raises your capabilities to another level. 6. Now let's talk uses and environment. In my opinion, if you intend to purchase this Eris Sub 8 for a large room, then I'd suggest a larger subwoofer (10" to 12" or higher). To me (I could be wrong here), this unit appears to have been designed for smaller rooms (bedroom size perhaps), or for an under the desktop scenario, or small recording studio. But hey, that's just my observation. Since I use it in an under desktop scenario, it does perfectly fine for me - no issues at all. 7. As for appearances, this Eris Sub 8 looks quite attractive, and did I mention the “size…?” 8. In closing, given its low price and very small size (for the genre), along with its superb performance parameters (once you get the gain setting right for your environment), I had to give it 5 stars. It covers many bases, and no it’s not perfect (nothing is unless you pay out the Wazoo for it). ... show more

  • Well worth it!
These are not good for someone who wants to blast either movies or music. If you want that you need to spend more in my mind. My upstairs system is comprised of many old pieces that took some time to set up properly in my living room. New pieces are a modest Cambridge Audio Integrated and Wiim Pro Plus. Both great for the money! I actually brought a second one and dialed them in to compliment old Tannoy monitors, etc. When spending time listening, adjusting, listening and more adjusting I was able to get them to blend with speakers and extend the low end. The high pass compliments the speakers and the levels are kept to a minimum on the subs. It's true I don't listen to music very loudly and it's also if set too high a level they just boom. All that is said to say they are now integrated wonderfully into my system. I couldn't be happier. They are small and fairly attractive. ... show more

  • This is just two funny!
This is just two funny equates to this, if You really want to have some fun listening to some good music, simply get two of these subwoofers. One of these subs will enhance Your music on the low end, but two, and You will feel the bass. Two subs actually fill out the room better and equally across Your listening area. Less volume is needed when using two of these subs equating to less distortion at higher volumes. Typically, people usually blow out one (their ONLY) sub by overdriving it constantly, which eventually leads to amp failure (sooner as opposed to later, if at all.) 50 watts continuous music may NOT sound like a lot of music, but it truly is, if it is clean and not distorted. Two subs and now You're talking about a 100 continuous wattage of music. I say continuous because I would not and do not play any of My speakers to achieve peak wattage, which is just that, peak wattage. Peak wattage can be damaging to speakers especially if the sound is distorted. I have these subs paired with My Klipsch "The Fives" and I Am over the top with the low-end reproduction of music. Tight, clean, precise, rich, full and low bottom end. Metallica, Aretha Frankin, Fleetwood Mac, Mandrill, The Ohio Players, Chicago, Earth Wind & Fire all sound full and rich. I play Khelani (Toxic), The Gap Band (Yearning for Your Love) and/or Nipsey Hustle and the music is clear, precise and low in frequencies. My Genres are old school R&B/Real Rap Music (80's early 90's), Blues, Rock, Funk, Jazz and a lil Country to round it out. Elevator and classical music are NO-GO'S, and I don't want to hear about females being degraded, drugs or violence being falsely disguised as music. Real music involves real musical instruments that are played by real and artful musicians that have meaning and positive purposes. I love to hear musicians finger slide across and pick their guitar strings. And please do NOT forget the brass sections and woodwinds either! For example, Metallica's Unforgiven, most people focus on the lead and rhythm guitars, but in ALL SERIOUSNESS, the drummer is VERY key in this song. The drummer is the timing and rhythm keeper in this song for sure. And a good sub will help You to see this also, kick-drum, snare, cymbals, crashing, punching, beating, rhythm! I want to hear it all in detail and with clarity! These subs do a great job in infusing music with depth and fullness; and warmth when needed. All they need are the complementing mid and high frequencies and it's game on! If You use two of these, they together can fill an averaged sized large room easily. My Klipsch "The Fives" and My ProSonus Eris Sub 8's do NOT compare to My Klipsch RF-7 II 7.2 set-up, NOR were they designed to. However, it does come very close to replicating the sounds that I get from My main sound system, and it is that sound that I was trying to achieve. Secondly, My left and right channels individually sound as one speaker (one sub/one of The Fives.) I set the gain on both subs to 50%, and from there I worked backwards in the direction of 0% using the sub volume control on The Fives remote control to make the subs function solely as an extension of the speaker in the low-end area. From this point, the master volume control is the only volume control needed for everyday playback. The crossover is set to 80hz. I use NO equalization, simply flat setting. I do NOT have to make any adjustments to My subs when playing music across different genres. When You have ONLY ONE sub out, You must buy a Y splitter containing one male end to plug in the single sub out jack and two female ends on the V side of the Y. I then purchased a Y split sub cable, all three ends male. This Y cable plugs into the left and right channels on the back of the sub (You can also use a single sub cable for each sub, but it must be plugged into the L or LFE input on the back of the sub.) I have both subs' settings identical, or You can adjust them individually according to Your listening preference and room environment (acoustics.) For Me, these subs were ideal. Also, I always use dual subs at home because of their inherent better listening acoustic across the whole of the listening area. Sure, I could have purchased a more power speaker with a higher output wattage, but even then, one more expensive sub does not sound a good a two less expensive, but good subs. In essence, two for the price of one, taking down two birds with one stone. Trust Me, had I purchased the more expensive single sub, at some point, I would simply purchase a second one to achieve the same results (balanced bass response across the entire room, as opposed to one half or corner of the listening area. Klipsch "The Fives" have a 4" driver that is responsible for both bass and midrange frequencies. As a result, because of its dual role and cone diameter, they are limited on the low-end frequencies reproduction, though they CAN reach deep on the higher end of low-end frequencies. Adding a sub or two (recommended) allows the bass drivers to focus more on the midrange and upper end bass frequencies for bass tightness and brighter midrange. The subs are responsible for bringing to life those low-end frequencies that We so desire. The bass port is front firing, so placement against a wall is NOT a factor, but room corners and speaker placement are still in play! I would recommend these subs if You love great sounding music, but don't necessarily want to break the bank in the process. Should anything change or the subs fail for some reason, I will post an update. Right now, the subs are a 5-star IMO. I use them for music ONLY, so I do not know how they perform in a theater environment or for those purposes. ... show more

  • It is better than i expected with a small cabinet!!!
I have a sub that is a 6" that I paired with a set of Presonus Ceres 4.5BT monitors. The bass was lacking and I wanted something a little stronger. I ordered it and It was delivered in 24 hours on prime. It is much smaller than I expected. It’s just 2” deeper than the 6" cabinet it is replacing. I connected it to the system with the Presonus Ceres 4.5BT monitors. It turns on right away. And it has strong smooth bass not muddy bass. I actually had to turn it down 5-7db below 0db on the gain control to match the monitors. Now, I have a complete Presonus system, that is very impressive for the cost. I have several other systems, A KRK VXT system and a Blue Sky system this is smallest system and it is very impressive compared to the KRK and Blue Sky systems I have in head to head comparison using the Mackie Big Knob 3. Very happy with this sub. highly recommended. ... show more
