I got this for my home studio and after using it to finish three songs since getting it, I can say I was definitely handicapped trying to produce and mix without a sub. I have the sub paired with my Presonus Eris 5 speakers. The songs I've produced using the sub vs. without the sub have translated much better across various speaker systems and my low end is much tighter and easier to manage. Also, when it comes to sound design, I can make much deeper and higher quality sub bass synth patches because I can actually hear and feel what I'm doing. I'd recommend using a calibrated room microphone and an acoustic room response calibration software to calibrate the sub and your speakers to your specific room as well. I found for my room I could just leave the sub in it's default configuration out of the box, but the settings on the back of the sub allow for some really nice fine tuning to get a nice flat response after accounting for the room response. Lastly, I really like the Bluetooth capability for casual listening and it works well if you only pair it with one device, but I found that if you want to switch between devices you have to press and hold the Bluetooth button on the back of the sub for it to connect to a different device each time despite already being paired. It connects automatically without that step if you just connect and use one BT device consistently with it. Kind of a weird and somewhat annoying quirk, but I don't really use the Bluetooth for anything but connecting my phone to the speaker system for leisure listening, and I only occasionally connect my laptop. For music production though, I use balanced TRS cables routed to my audio interface because the Bluetooth can add a significant amount of latency to the signal chain. In summary, if you already have Eris speakers and want to gain the valuable information your ears need to have great low end in your mixes I'd say this sub is a no brainer and worth every penny.

Great quality, design build and sound !

If you have any of their Eris monitors and you're considering getting this just get it. You won't notice why you need it at first... But when you get really complex dynamic mixes with a lot of mid-range a lot of lows... You'll get something called intermodulation interference or something like that... You'll lose detail things will become muddy and kind of distorted. It's not something you can spot right away but if you play really nice tracks and think they should sound better... More detailed.. this could be why... The subwoofer basically takes over on the low frequencies and it gives the monitors and chance to breathe they're not so busy responding to the lows... Oh yeah and the thing slaps it's so powerful.

This subwoofer is remarkable for deep base from an 8” driver, but that is only the beginning. It produces highly accurate sound across the bass spectrum. Instruments sound realistic and tonally correct, with spatial accuracy that far exceeds any bass unit I have owned in the past regardless of cost. And, the sound adjustments make it easy to blend with other speakers. Seriously- a great sub and a great value. That may read like ad copy, but to me it is a joy to endorse a product that has me listening to my CD collection again and hearing a whole new level of detail.

Several items to share. I purchased this with a pair of Presonus Eris 4.5BT monitors as well. First, many people don't realize these are studio monitors, and purchase them to use as a 2.1 system in a small setup, or as main speakers for an audio setup. One thing to realize is that studio monitors are not intended to make your music sound "good", they are intended to make it sound "true", the was that it is currently mixed. It's often said if you can make your mix sound good on monitors, it will sound good on anything. Many people are looking for deep base or boosted highs and are disappointed when they don't get that. If you are looking for monitors, these are very good for the money. For comparison, I also have a pair of Eris 3.5BTs, a pair of JBL 305P MkIIs, and a pair of Adam Audio T7Vs paired with an Adam Audio T10S sub, which I use all of for mixing, with the Adams as my main. In all fairness though, I really did purchase these to use as standard speakers on a computer, and only occasionally as monitors. Perhaps the most disappointing thing is that both the monitors and the sub have Bluetooth, but Windows has no easy way of outputting sound to both at the same time, so I have a BT connection to the sub, but TRS from the sub to the monitors. I would love to have seen this disclosed up front. I would also love to have had some sort of dedicated software to handle the simultaneous output, similar to what Samsung does for their phones. In theory I could make this work with Voicemeeter, which can create a virtual audio device that outputs to multiple audio interfaces, but the only reason I think this is because I can connect both via Bluetooth, and from Control Panel can play sound to either without changing the default windows output device, but it's a lot of work to get that set up. For now, the monitors will remain wired to the sub and I will hope Presonus decides to make something happen. Oh, one last thing to be aware of. In this configuration, you give up the use of the volume control on the front of the monitors since it doesn't control the sub. Instead, you end up balancing the system at a reasonably high volume and then resorting to using your keyboard volume controls.

Combined with a smaller set of monitors that can't do low frequencies as well, this really helps add depth to the sound. would absolutely recommend.

Compré 2 bocinas de 7" de esta misma marca y aunque ya tienen bueno graves la verdad es que la experiencia de sumarlas al subwoofer si es impresionante. Disfruto mucho no solo tocar el piano, producir y escuchar música, igualmente ver películas, series, escuchar podcast y hasta jugar videojuegos se volvió una experiencia mucho más envolvente e interesante. Con las bocinas conectadas por cables y este subwoofer a una tarjeta de audio lograba tener todo el audio de mi computadora pero además de todo sumarle vía bluetooth el audio de mi teléfono haciendo que pudiera tenerlos simultáneos incluso. Si de verdad eres amante de la música y estas haciendo tu home studio, te recomiendo mucho la experiencia de un subwoofer, este no es tan caro y es algo muy especial. Yo lo tengo debajo de mi escritorio justo frente a mis pies y no a pesar de no tener un cuarto tratado acústicamente la verdad es que no experimento resonancias ni nada raro. Creo que si bien en el día a día no noto tanto la diferencia de haber comprado los de 5", cuando escucho música desde el comedor o cuando me baño si noto la diferencia al poder subir mucho el volumen incluidos los graves. Igual la verdad te lleva al máximo volumen sin tener ni si quiera que subir a tope los aparatos siempre cuidándolos un poco al nunca llevarlos al máximo.

Llego antes de lo esperado y era algo mas grande de lo que esperaba pero no me importo, cuando lo conecte retumbaban mis ventanas, lo configure y su sonido es excelente mi estudio es de 3 x 4m y no tengo que subirle mucho de volumen tengo monitores presonus 3.5 y se complementan de maravilla, la mejor compra que he hecho

No sabes que lo necesitas hasta que lo tienes, no lo pienses, si tienes los Eris 3.5 o hasta los 5" este sub es maravilloso, ni opaca ni le falta, suena con un detalle y precision increíble, nada de frecuencias molestas, no se compara con ningún Estéreo, sistema de audio o componente, es super potente y hermoso, calidad en materiales, vista, sonido.

Recientemente pedí este subwoofer Presonus Eris Sub 8BT, con él y el par de Eris E5 completé mi sistema acústico. No siendo un experto en marcas para audio tuve la fortuna de encontrar a Presonus. Estoy muy contento con mi compra, me parece una excelente relación precio/calidad.
