Review: KEEP UP THE GOOD WORK, PRESONUS - Firstly, PreSonus have nailed it in my opinion - as a casual user of listening to music and making music for fun, I find this perfect - like way more than what I need. The build quality of the PreSonus 8BT Subwoofer is very nice, made out of this robust like metal, and it has this grill on the front incase if it’s on the floor, that you do not accidentally drive your foot in or you drop something and it falls on it, the grill should prevent that. The setup was fairly straightforward, I used a Focusrite Scarlet Series Interface for this one. I hooked up the Input of the 8BT Into my Interface, and then the Output 8BT to the Input of my Eris 3.5 speakers. They provide you with this plug for this speaker too. The volume is really good, the bass is heavy and the controls are amazing - you can control polar pattern, high pass filter and gain. It also has bluetooth, however it does hiss a bit though when using BT mode. The fit of the speaker is nice, because it is on the smaller side of subwoofers and you can easily put it in a small corner because this product is fairly small. Good product and keep it up PreSonus (it is my first day of owning)
Review: Seriously good bit of kit - I bought this and paired with their non Bluetooth monitors, which saved some money but still allows for Bluetooth listening! Sound is exceptional for the price and better than some more expensive brands (looking at you Sonos!)

## Features

- DEEP, ACCURATE LOW END: The Eris Sub 8BT compact 8-inch, front-firing studio subwoofer with Bluetooth input delivers studio-quality, accurate sound perfect for music production, hi-fi audio listening, or multimedia reference
- ADD A SUBWOOFER TO YOUR SETUP: Flexible connection options with balanced 1/4" TRS and RCA inputs and outputs, ensures easy compatibility with virtually any monitoring setup – so you can plug in, pair up, and get to work without missing a beat
- BLUETOOTH 5.0 CONNECTIVITY: Ultra-reliable Bluetooth 5.0 input adds convenient wireless playback from Bluetooth devices such as a phone or computer
- POWERFUL: The surprisingly loud, 100 watt Eris Sub 8BT drops down to a molar-rattling 30 Hz, so you'll hear the full sonic spectrum and produce better mixes
- FLEXIBLE FILTERING: A switchable highpass filter routes low frequencies away from your main monitors for a cleaner full-range system, while the lowpass filter control (crossover) ensures the Sub 8BT starts working at the precise frequency where your main monitors stop

### ⭐⭐⭐⭐⭐ Awesome sub, truly is a game changer if you produce your own music.
*by W***N on 12 August 2025*

If you produce any thing with any sort of base, it doesn't matter how good your monitors are, you need a sub. I have giod monitors and great headphones, but my mixes came out muddy as hell anywhere I played the music that wasn't a decent set up. Adding a sub to my set up has let me mix in those lows soooo much better and it's made playing it on sub standard speakers sound so much better too. So it made the mixes sound better on a good setup but also made it sound better on a crap set up and got rid of a lot of muddyness. Having a sub truly is imperative to producing/mastering your own mixes. Looks great, functions as you would expect, plenty of drive, connects through Bluetooth (though I have it set up connected to my monitors through cable) size is as stated so nothing to worry about if you have a specific area you want to place it. Not remote controlled but honestly who needs that when you have the controls on the PC right Infront of you. The Bluetooth is pretty useless I feel unless your whole system is set up on bluetooth, as you need to either have Bluetooth or your audio interface playing, you can't have them both on at once unless you can find a work around.
