Barefoot Sound MicroMain45 3-Way Active Studio Monitor - Pair

3-way active monitor condensing the MiniMain12 without sacrificing quality - features Multi-Emphasis Monitor Emulation (MEME) technology
MFR# MicroMain45

Product Description

The Barefoot Sound MicroMain45 studio monitors deliver the same legendary sound of the renowned MiniMain12s in a compact, affordable package. Designed for engineers, producers and musicians working in smaller facilities and home studios, the MicroMain45’s captures the signature Barefoot sound with zero compromises.


The MicroMain45 is an active 3-way near field monitor with four cutting-edge drivers. An 8-inch aluminum cone subwoofer delivers tight, punchy low-end all the way down to 40 Hz. Dual 2.5-inch midrange drivers provide a focused midrange, while a 1-inch tweeter extends up to 45 kHz for super-detailed sound. And with dual ring radiator technology, the MM45s offer an extremely wide sweet spot for consistent sound in any position.


Barefoot has teamed up with Bruno Putzeys of Hypex to develop a powerful and completely transparent amplifier design for hyper-accurate sound. The MicroMain45 is equipped with three class-leading amplifiers, with 250 watts powering the subwoofers and dual 180W amps powering the midrange drivers and tweeter.


All Barefoot Sound studio monitors are equipped with Multi-Emphasis Monitor Emulation, or MEME technology, which uses sophisticated DSP processing to emulate the sound of a wide range of classic studio monitors. Quickly reference your tracks on three additional monitor profiles and ensure your mixes will translate to any environment.

“Old School” mode emulates the sound of the iconic Yamaha NS10M monitors with an edgy, midrange-forward sound. The “Cube” setting is modeled after the legendary Auratone Sound Cube, giving your mixes a boxy, lo-fi sound. On the opposite end of the spectrum, the “Hi-Fi” setting emulates the sound of consumer hi-fi systems with a sweet high-end and warm midrange. And of course, the “flat” setting delivers the signature Barefoot sound that engineers, producers and musicians around the world have grown to know and love.

“I need a monitor that is just very clean and precise and doesn’t add to the chaos I’m already creating. What surprised me about (the MicroMain45s) was most of the time, when I use monitors, it takes me a while to get used to them in the room they’re in, and the first time I put these guys in my office, it was like I was just already acclimatized to them. It was strange. It’s never happened to me before. It was like there was no, normally I’d have to listen to a ton of prerecorded albums and stuff that I know and get used to everything, and I didn’t have to do that with these. Yeah, I mean, I just really think they just give a real representation of what is being played and it just helps me create.”
- Alex Da Kid, GRAMMY-Nominated & Multi-Million Selling Record Producer

“The most important thing for me is that what I’m hearing is true, that I can trust what I’m hearing, and also a speaker that’s going to give me the positioning that I want, the detail that I want. I get into such finite detail of positioning and delays, and delays that go into reverbs. Maybe you don’t hear the delay, you just hear the reverb, and the reverb has reflections, but reflections have to cut off before the next part comes in, so my listening experience has to be absolutely precise.

I’ve been working with these Barefoots, the mm45s, now for about a month, and really love the definition in the high mid-range. The bottom end is great, it’s warm. I always love a lot of bottom end in my mixes, but the hardest thing on most speakers is to get that definition in the mid-range, because that’s where you hear a lot of the reflections in your reverbs and a lot of the delays.”
- Adam Moseley, Producer/Engineer/Mixer (U2, Beck, Lenny Kravitz)

The Barefoot MM45s are top shelf monitors! I’m using these in addition to Lipinski 707s. The Barefoot's shine where the Lipinski’s don’t. They are the most complimentary set of monitors I’ve worked on in 30+ years of making a living in this crazy biz. Thanks to Joe Dickenson at VK for recommending these monitors. Several ideas were floated but he was instrumental in correctly directing me to the Barefoots. These will be in my studio for a long time!

The MM45 exceed my expectations. Such a true representation of sound.

By Trevor S on October 10, 2021

I have a $12,000 pair of monitors and I almost never listen to them because i make dance music and these Barefoots are just better suited for it.

By Barclay C on March 22, 2021

Had a healthy budget in my search for
new monitors. Tried out a bunch in my room. The mm45s won out even against some more expensive options. I love the clarity in the low mids. It’s easy to hear what is mud and what is warmth or what is rich bass and what is flab. Sealed box makes for a smooth roll-off with useful information below 40hz. Upper midrange is detailed and 3D. Tweeter is non-fatiguing and smooth. Imaging is excellent. I use the “Meme” switch more than I thought I would to check to make sure the harmonics on 808s and such are audible on the “cube” setting. I wish I had made this upgrade sooner. Monitors are a very personal choice, but these barefoots are perfect for me.

Oh and they’re great production monitors, too. They’re fun and analytical. The best of both worlds.

Love love love

By far the most transparent monitors I’ve ever worked on. Very fun and musical to use.

By Josh M on October 24, 2020

These are incredible no doubt. A serious step up from slightly less expensive speakers like the KH310's and focal Twin Be's. The clarity and dimension from them are truly top notch. The one reason I can't give them 5 stars is probably unfair but how I feel. They just don't go very loud. They start to limit VERY quickly into higher volumes. I make electronic music and so sometimes it is desirable to bump the speakers loud while writing. These just don't quite get to that thump level of volume that would make them 5 stars. That being said they aren't really mains so that kind of makes sense but I would've liked a bit more oomph from them. I'm thinking about getting the subs that go with them to see if that helps. So for writing and tracking they lack some of bigger speakers but for mixing they're just incredible.

By Lucas on September 24, 2020

These are effortless. If you allow your ears to trust what is coming out of these speakers, your mixes will work anywhere you play them; and I do believe that's the goal of any self-respecting studio monitor, if I'm not mistaken. Buy them, let go of the compensatory habits you developed on lesser monitors the best you can, trust them implicitly, and win more clients.

Side-note: Don't be afraid to try them in the vertical orientation.

By JJ on June 13, 2020

Coming off a pair of Amphions that weren't killing it for me, I've been pretty blown away by the improved quality of my mixes and reduced need for much touch up in mastering. I find the overall balance spot on, with a nice sized listening sweet spot and clear mid and hi end detail. They can be impressively loud and clean for tracking and when I need to impress clients, but great to mix on at a lower volume. Something I couldn't get from my Amphion 118's - Low end rolled off too much and couldn't handle any volume.

This was my first experience buying something from Vintage King (although I surf the "used" categories on the website frequently!), and, despite being on the other side of the world, I had absolutely no trouble and everything went very smoothly.
