## 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: Powerful, Clean Bass with Bluetooth - Huge Upgrade to my Setup - This subwoofer seriously impressed me. It's a beast for its size. The power is the first thing you notice, it hits hard and clean without getting muddy. For an 8-inch sub, it delivers deep, punchy bass and can easily fill a room. It’s rated around 100W and can reach down to roughly 30 Hz, and you can absolutely feel that low-end presence. The controls are where this thing really stands out. You get adjustable input gain, a variable low-pass filter, and flexible tuning options so you can dial it in perfectly with your speakers. It’s not just plug-and-play (although it certainly can be), you can actually fine-tune your sound, which makes a big difference for both music production and casual listening. In terms of versatility, it works great across the board: studio monitoring, gaming, movies, or just listening to music. The Bluetooth feature is a nice bonus too, making it easy to connect without extra cables when you want a simpler setup. As for value, it sits in a really strong spot. It’s not the cheapest sub out there, but for the performance, features, and overall sound quality, it absolutely justifies the price. You’re getting something that feels much closer to higher-end gear than budget equipment. Overall, this sub adds a whole new dimension to your setup. If you want tight, controlled bass with real customization options, this is an easy recommendation.
Review: Impressive for such low wattage - I've got the Eris BT5's to go with this subwoofer. My buddy heard these in someone's home down where he lives and said that they sound amazing for a "budget" Monitor set. He wasn't wrong. I can't even open the set up because at about 50% volume in a 12x12 room, it's boomy and loud. You do have to EQ these though. The highs and lows won't be as rich without an EQ. Because both the Subwoofer and Sat's are BT, you do have to hook both up to a PC to get sound out of each and together. Now you know if you didn't and was like what. You'll also want to go ahead and get some RCA cables or the TRS cables, because they don't come with either for Sub to Sat connections. The Sat's come with RCA to 3.5mm and a 3.5 to 3.5 cable for phone/tablet/headset pass thru/whatever. I went with White because I'm building out a contrast setup with White n Black aesthetics. They look nice too. Good value for the cost. The next set up from these in another brand run about 250 a satellite and 300 to 500 for the matching subwoofer. The Eris 5BTs do pair up nice with the 8BT.

- PRECISION-TUNE TO YOUR ROOM. High- and low-frequency tuning controls allow you to customize your audio output for your ears, room size, and speaker orientation.
- QUICK-SWITCH TO HEADPHONES. The easy-access front panel headphone output and built-in headphone amplifier allow for plug-and-play headphone media reference when needed.

### ⭐⭐⭐⭐⭐ Sound Fantastic, Pairs well with JBL 305P MkII monitors
*by D***K on July 3, 2026*

I've got a small bedroom studio and have recently started my journey of music creation. Have a pair of JBL 305P MkII monitors that sound awesome, but wanted a sub to hear that 80Hz and below range for electronic/EDM/bass pads. Got them tuned quickly - 'normal' music has enhanced bass but not so loud that you notice the sub. It just mixes very well. With EDM and other thumpa thumpa thumpa music or music with very low bass or pads the sub really shines. You get the full bass range that you can feel in your chest and a huge grin on your face. Stoked that you can get a sub with this great of a sound that functions so well for the price. Installation was a breeze - used 4 TRS cables - 2 out of a Scarlett box into the input on the back of the sub and 2 more from the out ports on the sub to the monitor speakers. The box was actually a bit larger than I thought it would be - nice and beefy.
