Give your room a little boom! The Eris Sub8 is the first subwoofer to join the lauded and best-selling Eris studio monitor line. Presonus called it Eris because it's been designed from the ground up to be part of the family. It compliments the voicing and frequency response of the modern Eris classics. The surprisingly loud 100-Watt Eris Sub8 drops down to a molar-rattling 30Hz, allowing you to both rock harder and produce better mixes, as you'll be hearing an accurate representation of your work. Thanks to robust configuration and I/O, you'll be able to tailor your Eris Sub8 configuration exactly to your mixing and listening needs. You can connect your existing monitors via 1/4" TRS or RCA, set the input level to your liking, and even invert the polarity. Most importantly, you get a High Pass Filter and a Low Pass Crossover control that ensures your Sub8 starts working at the precise low-frequency point where your main monitors stop working. This makes sure you avoid the flubbery, smudged, low-end mess that one hears in redundant, duplicate, redundant bass reproduction that occurs without a crossover.

Great little sub


Amazing subwoofer for my home studio. Compact and powerful. Has really helped me in my mixes and given me a nice low end!



Excellent subwoofer, great value!


I've been a customer at two other major online retailers for a long time. They were out of stock on this sub, and they didn't know when they'd come back. A friend suggested Sam Ash, and they had it in stock! Great customer service and fast shipping, I now have a new go to place for gear! The sub sounds amazing, and pairs great with my Sterling Audio and Kali Audio monitors. Very happy customer!
