Tenía conectadas mis bocinas estudio Eris 3.5 a la TV. Pero sentía que le hacía falta algo. Y ese algo es el subwoofer. Ahora parece que estás en el cine.

El Presonus Eris Sub 8 es un excelente Sub Woofer, se escucha muy bien, lo tengo conectado a dos bocinas Edifier P17 con un amplificador Fosi BD30D Pro y el conjunto suena muy nítido, los bajos y agudos claramente separados y las voces se escuchan muy bien !! El amplificador se calienta, nada de que preocuparse ( en reviews de este amplificador mencionan también que se calienta pero sin tener problemas )Tengo pensado comprar otro para conectarlo a un teatro en casa !!

Tengo un pequeño estudio casero y funciona a la perfección, solo un comentario porque en ningún lado lo explica. Las bocinas que quieras conectar en el subwoofer deben ser activas si no no van a sonar.

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.

I am not an audio technician. I do a bit of video editing at work and decided that my cheap creative 2.1 speakers really were not doing me any favors when dealing with difficult voice audio. I picked up a pair of E5 monitors and this Eris sub along with a Scarlet 2i2. Holly cow, my expectations were blown away. I had the sub a little too high as you can see in the attached frequency measurements but holy cow look at those E5s in a completely untreated room!Anyhow, I let SoundID Reference calibrate them for me and the whole system has been an absolute pleasure and unbelievable considering the price. I have a nice flat response all the way down to 30 Hz.So, I decided I wanted to get back into dabbling with audio production at home. I already had a pair of the old inexpensive Samson Resolv A5 "monitors" but after a bit with them I knew I needed a subwoofer. I didn't even think about it and picked up this Eris 5.Well, I plopped it down in the corner under my desk and.... Ugh. It struggled to get down below about 43 Hz or so. I brute forced it with volume and SoundID. That got it down to about 35 hz or so but it was clear I was pushing it too hard in some music at 85 Db reference as it would huff like crazy and even break up a bit.Turns out in my particular room, having the sub in the corner near me was the absolute worst position. It cancelled out deep bass frequencies. four 30' balanced TRS cables later and I am happy. I had to put the darn thing in the opposite corner but it dips down to 30 Hz perfectly now just like at the office. Luckily the A5s get down to around 55 hz pretty well so the sound from the sub is not particularly obvious from behind me.So yes, this sub really does hit down to 30 Hz as advertised (drops like a rock after that of course). It's surprisingly small for its performance capability. Someday I should do a nearfield measurement on it. From my posted measurements in an untreated room it is obviously going to have peaks and troughs but to the ear, it is still very pleasant even uncorrected.I would recommend this low end presonus line to people in a second. Shoot, you can pretty much use the E5s right out of the box and get amazing results.Update 9-18-2023: I had something of an odd failure on my sub. All of a sudden the High Pass Filter started attenuating all frequencies (not just below 80 HZ) and only in the left channel. I contacted Presonus support and after a day of email troubleshooting, Fender (yeah I guess they must own Presonus) sent me out a brand new sub which was at my door in 3 days. That's pretty good.

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=13. 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).

Si tienes un Home studio con un par de monitores de menos de 7" este subwoofer es el complemento ideal para ellos ya que escucharás los graves mas definidos y claros.

De las mejores cosas que he comprado en mi vida. Tengo conectados, dos echo dot 3ra generación, uno 5ta generación y un echo plus 3ra generación, y quería conectar un buen sub woofer, sin duda el haber conectado éste a uno de mis echo dots me ha dado ese sistema de sonido completo teniendo bocinas por toodas partes de la casa y con graves profundos

Its strange how powerful it is. To level match with the Eris 3.5 the gain knob on the sub is about turned all the way down which almost feels like a defect. Hence the 4/5 stars i give it. But once its setup i was pretty blown away by how big the setup feels/ is together. Just make sure the crossover freq is set correctly as well or it will be a mess. Took me a bit using only ears to get the feeling right. Dont rely on the numbers too much,, use it as a starting point.

I was looking for a solution to add a little more bass to my KRK Rokit 5 monitors. I did not go wrong with this small yet surprising studio subwoofer.Power : Out the box, the sub looked very small and I was concerned about it's power. Listening in a 10ftx10ft room, the sub delivers plenty off boom for my room. I even had to turn the gain down to about 1/4.Sound quality : This is where it gets interesting. The quality of the sound is stunning. You can hear the precise kicks in rock music, and feel them low ends on dance and hip-hop. This is not the type of sub to feel the bass in your chest, but to appreciate a well balanced audio with small to medium speakers it does a wonderful job.Connectivity : You'll get possibly any connection option you're looking for. I cannot rate more than 4* on connectivity because of the lack of XLR ports and no ground lift switch, but at this price point you cannot go wrong. You still get unbalanced RCA and balanced 1/4 jacks for input and output. I like the fact that you can adjust the Low Pass with a knob instead of few preselected frequency.I was hesitant between this sub, the mackie 8 inch multimedia sub with remote and the KRK 8.4. After reading bad reviews on the build quality about the Mackie, I was left with the KRK and the Presonus. I went with the Presonus because I liked the sleek design more and the added protective grill which isn't included with the KRK. Plus, it won't break the bank.TLDR : Great small sub. Precise bass. Great build quality. Great connections options.

Siempre pensé que los Eris 4.5 eran ya bastante buenos, a pesar de llegar solo a los 50 hz en cuestión de bajos. Sin embargo, estos Eris Sub 8 llegan a complementar perfectamente mi estudio debido a su reproducción de hasta 30 hz.La respuesta a bajos es precisa, definida, sin distorsión, impresionante.Mi habitación es pequeña, por lo que este subwoofer lo llena y hace que retiemble. Tiene potencia de sobra.Lo recomiendo ampliamente a quienes ya cuenten con unos Eris. Aunque funcionarían con cualquier otro monitor de estudio.

Es un subwoofer que sinceramente ha cumplido mis expectativas y las ha cumplido con creces. Desde el primer momento que lo escuchas notas al instante la diferencia.Este subwoofer lo compré para complementar el sonido de unos PreSonus Eris 3.5. El uso que le doy a los PreSonus Eris 3.5 es de consumo y multimedia, de vez en cuando para probar algunas mezclas, pero nada más allá de eso, entonces, suelo jugar mucho videojuegos y quería probar algo más de graves, y también para las películas y he quedado muy sorprendido de la limpieza y naturalidad que te ofrece este subwoofer. Al calibrar los monitores de estudio y escuchar muchas canciones, así también jugando bastante y viendo películas, puedo decir que estoy gratamente sorprendido.El subwoofer está conectado a los monitores de estudio mediante un cable TRS y el subwoofer por un TRS a auxiliar (sé que no es lo más puro, pero va de maravilla).Como punto extra, convertí todo el sistema en un "altavoz inteligente", mediante la conexión del subwoofer por RCA hacia 3.5mm y lo conecté a un Echo Show 5, y ¡qué maravilla!Si tienes unos monitores de estudio como los Eris 3.5 o 4.5 y quieres un poco (mucho más) de bajo, que cubra a menos de 80Hz (límite de ambas bocinas), entonces, este subwoofer es para ti. 
No te vas a arrepentir de ninguna manera.Pros:+ Excelente claridad de frecuencias bajas.+ Excelente construcción.+ Buen complemento con tus monitores de estudio (no necesariamente PreSonus).Contras:- Solo trae adaptador de corriente, por lo que deberás conseguir Cables TRS o RCA por separado.Conclusión:Lo recomiendo mucho, y lo volvería a comprar sin ningún problema.
