Designed to perfectly complement Eris monitors, it offers variable lowpass and highpass filters, balanced TRS and RCA connectivity, and a polarity invert switch for phase correction.

## Description

Product Description The single best subwoofer you can get to put a little boom in your room, the Eris Sub8 is the first subwoofer to join the lauded and best-selling Eris studio monitor line. We 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 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 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.

## Questions & Answers

**Q: Does this come with all the necessary cords to connect this to a computer? Is it rca trs or xlr?**
A: It depends on which speakers you order. The 3.5 and 4.5 come with everything necessary, but the 5 and higher definitely do not come with everything you need. Just the speaker and AC adapter.

**Q: Is the the Presonus E3.5 woofer speaker cone unprotected?  It appears to have no fabric covering as many speakers would have.**
A: Take a piece of t-shirt and bring it back and forth between your face and the monitors.. you will hear that even something like a tshirt of pantyhose, has a considerable effect on the sound projection. Also, having grills on the speaker looks cheap imo..

**Q: I am a Motivational Speaker, can I use these with a microphone when speaking to an audience of 75 people?**
A: There are better choices for that -- you want speakers with a built-in mic preamp, and probably higher wattage amplifiers. You may also want folding speaker tripods.
I suggest you puchase speakers designed for this, with a tripod screw hole on the bottom, and XLR mic inputs. For example, Bose EONS sound amazing for music as well.
You may also wish to purchase a good wireless mic.
Think of it as a system.
The size of the room and the audience determine the required size and power of speakers.

**Q: Do the Eris 4.5 mute themselves when a headphone is connected?**
A: Ideally they should, unless you’re using the Presonus Audiobox (or any other audio interface) and you connect headphones to that. In which case, they won’t mute.
