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. Of course, they’ll play nice with other monitors, too, but if you’ve got a pair of Eris in your home or studio already, the Eris Sub8 is the single best subwoofer you can get to put a little boom in your room.

The surprisingly loud 100-Watt Eris Sub8 drops down to a molar-rattling 30Hz—a full 50Hz below the Eris 3.5s. This allows you to both rock harder and produce better mixes, as you’ll be hearing an accurate representation of your work. For EDM and hip-hop producers in particular, a sub is a must-have.

The Eris Sub8 lets you naturally extend the reach of your Eris E3.5 or E4.5 monitors in a manner appropriate to smaller rooms; exactly where these monitors excel. 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 ¼” 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 Eris 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.

While we’ve designed the Sub8 to compliment PreSonus’ smaller-form Eris media reference monitors, PreSonus also know that gamers, partiers, and movie buffs alike all enjoy some room-rattle now and again.

So rest easy knowing that the Eris Sub8s will upgrade the performance of any powered speaker configuration in a home theatre or gaming rig.
