## Description

Our best selling studio monitors just got better! Eris® 4.5BT media reference monitors deliver studio-quality sound in an elegant, compact form factor that makes them ideally suited for bedroom studios, video production, and high-fidelity gaming setups. With 25 watts per side of onboard power, the Eris 4.5BT reference monitors pack a serious punch, while still delivering clear, accurate audio. The weave and nature of the Eris 4.5BT's 4.5-inch woofer result in tight bass that you can feel, as well as cleaner overall sound. The one-inch silk-dome tweeter produces refined high-frequencies and is designed to radiate sound with a wide pattern, creating a large optimal listening area. Improved speaker voicing over previous designs delivers richer lows and a smoother crossover transition for articulate, accurate transient reproduction through the frequency range and a less-fatiguing listening experience. A convenient front-panel knob sets the level of both the power amp and the loud, clear headphone amplifier, with its front-panel jack. With four types of inputs, including fast, reliable, stereo Bluetooth® 5.0 connectivity, it's easy to connect just about any audio source to your Eris 4.5BT reference monitors. High- and low-frequency controls let you easily adjust your Eris speaker's frequency response to compensate for the acoustics of your space and create the most accurate sonic reproduction possible.

Review: The bass in this one is to behold. - The sound quality, super good. The bass, super good. The price, way better than average. All I'd say is this is really good for either desktop or simple budget home theatre.
Review: Price Performance 1A+++ Top absolute amazing BASS and Sound quality - I am usually very critical person, because my focus is the price performance of a product and with this Speaker, I got very impressed how GOOD they are. I am using them at home on my working desk, just for commercial music/ videos/ movies streams by youtube, spotify and netflix. Room size apprx. 60m² (living room) 700sqft. ( I am not pro Dj or something) They are really powerful, Bass and sound very clear and loud. Even if you do some private invitions in your home, for a small group (5-7) House party they are very usefull. No need to buy any extra cable, in case you are limited in length, supplied length 1.50m! the purchase definitely worth it !!

## 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.
