PreSonus ERIS Sub8 Front-Firing, Eight-Inch Studio Subwoofer

The Eris Sub8 is the first subwoofer to join the best-selling PreSonus Eris studio monitor line. Designed from the ground up, it compliments the voicing and frequency response of the modern Eris loudspeakers. The surprisingly robust 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 a more 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 blubbery, smudged, low-end mud heard in duplicate, redundant bass reproduction without a crossover.
