PreSonus Eris Sub8 active subwoofer features an 8" front-firing glass-composite woofer, 100W power, built-in tuning controls, stereo 1/4" TRS and RCA inputs and outputs, a variable low pass filter for creating a seamless crossover transition and a switchable 80Hz high pass filter to optimize performance with satellite speakers. Ideally suited to complement compact media reference and studio reference monitors without overshadowing them, Eris Sub8 provides robust tuning controls and delivers smooth, low-frequency transients.
- 8" front-firing paper-composite low-frequency transducer with high-elasticity rubber surround
- Class AB amplifier: 100W peak (50W RMS) power
- Input gain control: -30 dB to +6 dB, continuously variable
- Continuously variable low pass filter: 50Hz to 130Hz
- Defeatable high pass filter removes frequency content below 80Hz from the full-range signal sent from Eris Sub8 outputs to the main speakers
- Left and right balanced 1/4" TRS and unbalanced RCA main inputs
- Left and right balanced 1/4" TRS and unbalanced RCA pass-through outputs for connecting satellite speakers
- Polarity invert switch
- Protection: RF interference, output-current limiting, over-temperature, turn-on/off transient, subsonic filter, external mains fuse
The single best subwoofer you can get to put a little boom in your room, Eris Sub8 is the first subwoofer to join the Eris line and complements the voicing and frequency response of Eris studio monitors. This surprisingly loud sub drops down to a molar-rattling 30Hz, allowing you to rock harder and produce better mixes since 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.
