## Overview

The PreSonus Eris Sub 8BT is a compact, 8-inch powered subwoofer designed for professional music production, home theater, and gaming. Featuring a 100-watt amplifier and woven-composite driver, it delivers precise bass down to 30 Hz. Bluetooth 5.0 wireless connectivity pairs effortlessly with multiple devices, while adjustable crossover and tuning controls allow for perfect integration with your existing monitors. With versatile input options and a power-saving mode, it’s engineered to elevate your audio experience with studio-quality low-end accuracy.

## Description

Adding a subwoofer to full-range speakers enables you to hear the low-frequency foundation of your music more accurately. The surprisingly loud Eris Sub 8BT delivers clear, accurate sub-lows down to 30 Hz, so you’ll hear the full sonic spectrum for music listening and content creation. For EDM and hip-hop producers, a subwoofer is a must-have. Flexible connectivity options, including stereo Bluetooth 5.0 wireless input, and onboard controls let you effortlessly create a 2.1 monitoring system and tune it to your room. Although compatible with a variety of full-range studio monitors, the PreSonus Eris Sub 8BT compact studio subwoofer was designed to complement Eris and Eris Studio-series monitors.

Review: Deep and Dark SubSoundz [Techno/Ambient] - The Eris Sub 8 absolutely KICKS. I’m running a full hardware rig—everything from the Erica Synths Perkons Hd-01 and Moog DFAM/Soma Lyra 8 and Sonicware Liven Ambient O—all through a Zoom L-12. This sub handles the raw power of analog synthesis and Eurorack levels like a champ. For modular gear, the output is on ANOTHER LEVEL. It delivers that deep, dark, and heavy low-end you need for hardware jams, but here’s the best part: it stays crystal clear. It’s punchy, not muddy. If you need a sub that can handle the aggressive transients of a RAT distortion pedal or the sub-harmonics of an Oxi One sequence, look no further. You can dial it in exactly to your ears. 10/10 for any hardware-based studio.
Review: Much better mixes - 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.

## Questions & Answers

**Q: don't bluetooth speakers have a lag / latency / delay??**
A: Yes, at it is really bad.

**Q: If I buy the Bluetooth version, will it also connect to the studio speakers connected to the subwoofer?**
A: There are 2 balanced 1/4” jacks and an unbalanced rca jacks on the back of one speaker. With that being said it depends on how you would connect everything. I run everything through my controller and use the E3.5’s as monitors as I play through my EV SX200’s on gigs. I hope this answers your question about the sub.

### ⭐⭐⭐⭐⭐ Perfect for my beginner studio.
*by J***. on March 18, 2026*

Purchased this sub to round out my PreSonus 3.5 speakers and to get the bluetooth capability that comes with it. So far, it's great. It has completely rounded out the sound of my system and also lets me play all my stuff from my phone. Everything I needed and asked for. Great sound!
