Powerful 100-watt Subwoofer with Bluetooth

There's standard bass-frequency monitoring, and then there's the Eris Sub 8BT Powered Bluetooth Studio Subwoofer from PreSonus. Touting versatile user setup options and control parameters, this 100-watt monster is a solid solution for small-scenario studio monitoring and hi-fi audio playback. Its 8-inch low-frequency driver supplies more than enough oomph to keep track of your low end. Though it's an ideal companion for Eris Pro and Eris Studio series studio monitors, the Eris Sub 8BT is an excellent addition to most any monitoring setup, providing clear-cut performance wherever it's required. Order yours from Sweetwater today.

Seamless user controls produce a signature sound

Different studios require different setups. Thankfully, the Eris Sub 8BT easily integrates any smaller-scale workspace. RCA, 1/4-TRS, Bluetooth — no matter what connectivity equipment you're working with, the Eris Pro Sub's back panel will provide a solid hookup option. Once you're connected, the subwoofer's included highpass and lowpass filter controls allow you to home in on (or filter out) the frequency spectrum of your mix. Fine-tuning your frequencies at a moment's notice during critical monitoring situations is a cinch with the Eris Sub 8BT.

PreSonus Eris Sub 8BT 8-inch Powered Bluetooth Studio Subwoofer Features:

  • 8-inch powered Bluetooth studio subwoofer with front-firing glass-composite driver
  • Natural low-end detail for studio-scale monitoring setups
  • 100-watt Class AB bi-amplification supplies more than enough power to fill the studio with traditional, untampered sound
  • Variable lowpass and highpass filters provide pin-point control of your output
  • -30dB to +6dB input gain control
  • Balanced 1/4-inch TRS inputs — unbalanced RCA main inputs
  • 1/4-inch TRS and RCA outputs

Very impressive for the price

I wasn't really expecting anything amazing from these and just wanted a cheap sub for now. Man was I surprised! This is the only sub I will ever need and I'm very happy with my purchase! Thank you sweetwater and Rob is the man!

Great Addition!

I use Eris E7xt's, and this sub supports all the frequencies below 80 hertz. My mixes in the low-end transfer better now. In my boombox, car or blue ray the mix sounds the same.

Good vibrations

My new purchase was one of great luck...this puppy sings so nicely. It's brought life and depth to each and every song..the lows are so clean and punchy and all I can do is smile when the lows come in and introduce themselves...Money just well Spent..Todd from kentucky

Presonus 8BT 8” subwoofer

Great addition to this home studio. Provides just enough bass end extension to my Roland DS-7 powered monitors. I hesitated to add a subwoofer not being certain of its added value and concerned the bass extension would warp my mixing. But it has been very easy to dial in the optimal bass level so as not to taint my ears as I assess mixing needs.

Presonus Sub 8 BT

This was a Christmas gift from my wife (I told her what I wanted). This is my 1st sub so I can't give it 5 stars because i don't have anything to compare it to.
However, it adds sooooo much to my home studio. It compliments my Eris 4.5's and I believe I'm getting a more honest sound from my mixes. Evan is my guy at Sweetwater and he helped my wife with everything.
Easy connectivity.

Sweetwater and PreSonus go way back, and that makes a lot of sense. Like Sweetwater, PreSonus is largely staffed by active musicians, songwriters, live sound techs, and engineers, and like Sweetwater, their culture shows up in everything they do. Early on, PreSonus broke ground by offering super-affordable audio interfaces that brought quality recording to home studio engineers everywhere. In the following years, we've been with them as they introduced a powerful, artist-friendly DAW, groundbreaking digital mixers, and more - all products we at Sweetwater use ourselves. One thing that's never changed, even as PreSonus has branched out into new territory, is that they've always done everything possible to provide you with the best value, and we're proud to stand by their products.
