Review: Outstanding clarity, detail and flat clean sound - Eris Accent BT 4" Wood Grain (connected via USB): These are VERY nice monitors. I always prefer monitors for my office computer speakers for the flat, uncolored response, and that is what these deliver. These replaced a pair of Mackie bookshelf monitors that gave up the ghost on the left/passive channel. There is a beautiful level of presence, detail and clarity in both vocals and individual instruments on the Eris Accents that makes it feel like I'm listening to certain songs for the first time. Very nice, and considerably better than the Mackie's. Low end is solid all the way down to where it naturally cuts based on the driver dimensions and port resonance. Of course, the rest of the low end below this point is attenuated. Will eventually make this setup a 2.1 by adding the PreSonus 8" Sub to fill out the low end. In the meantime, I added +3db on the low end eq on the speaker which helps a bit but want to get back to that uncolored sound across the full spectrum. There is plenty of volume for my home office. Set my Windows volume to 50% then dialed in the mid-level of loudness that I desired via the speaker remote (remote is line of sight only), and this results in plenty of volume control via Windows alone. Connectivity options abound. Besides USB as my main source, I'll route my Echo out to the 3.5mm port, and connect my phone on BT. This amp is really clean through the USB connection, with absolute silence between tracks on desertcart Audio using the Ultra HD quality setting. This is another area in which the Mackies lacked. Overall very good monitors at a reasonable price. Highly recommended.
Review: Amazing Speakers, American Company - Bought these to replace my failing 10 year old Bose Companions. I was really sad when my Bose went out butt these speakers are amazing for the price. They sound better than the Bose but 3x louder and more base. You can’t beat the price for the performance provided, all the jacks, the build quality, physical tone knobs, and its nice to buy from an American company that is focused on quality instead of stupid LEDs and useless features.

## 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.
