Barefoot Sound is proud to introduce the second generation MM27. Now featuring our amazing MEME™(Multi Emphasis Monitor Emulation™) technology, the MicroMain27 Gen2 precisely models the essential response and translation characteristics of other classic studio monitors, simply with the turn of a knob. If this weren’t enough, the renowned MM27 is augmented with advanced new electronics and drivers giving it even greater dimension and transparency across the entire audio spectrum.


The MicroMain27 Gen2 is a 3.5-way active system with 5 drive units housed in sealed enclosures spanning 30Hz to 45kHz with vanishingly low distortion, breathtaking dynamic range and ultra-fast transient response. The ring radiator tweeter is incredibly detailed and produces very wide dispersion out to its highest frequencies. The new 5.25″ midbass features a phalanx of advanced technology, yielding midrange detail that rivals any driver on the planet. Barefoot has teamed up with the brilliant Bruno Putzeys of Hypex to develop the powerful and completely transparent amplifier stage of the MM27 Gen2. Melding the system together is a groundbreaking new DSP crossover that has taken Thomas Barefoot more than 4 years to develop. With beautifully designed high end converts and cutting edge proprietary filtering techniques the MM27 Gen2 sound stage is seamlessly coherent and deeply revealing. 

MEME™ Technology: Despite the advantages of high resolution monitors, Thomas Barefoot realizes that many engineers still use their NS10M’s † and mix cubes as secondary references. These speakers have long traditions and people find them familiar and useful for focusing in on certain aspects of their mix. However, crowding one’s console with those extra boxes degrades the sound field of the primary reference monitors. Not to mention, they are no longer manufactured, they need amplifiers, cable runs, and they consume more studio space. The solution is to make the MM27 sound and translate like those speakers. With the turn of a knob one can switch from the MicroMain27’s brutally revealing “Flat” response to the warmer and sweeter “Hi-Fi” setting, generically emulating the sound of some high end consumer audio gear. More specifically the “Old School” setting closely emulates the sound of the NS10M nearfield, while the “Cube” setting emulates the mid-centric sound of classic mix cubes The idea is not to perfectly replicate every subtle quirk of these venerable old speakers. That would be impossible. But the MM27 Gen2 can capture the essence of how they behave and translate, modeling their frequency, phase and transient responses, dynamic compression and even specific distortion components. If you know how to work on these speakers you will feel very comfortable working on the new MM27’s emulation settings.

Unlike many other pieces of gear, monitors are a very personal choice. I’ve been mixing on one set of midfields for the past 20 years. During that time, I’ve A/B’d them against most of the popular contenders. None showed the potential to improve my mixes until Mike Nehra at Vintage King asked me to try a set of Barefoot MM27’s. They sounded great on first listen but would my mixes translate accurately? If so, I’d be super impressed and open to change. As a large midfield monitor they offered me an accurate response from a big bottom, warm punchy midrange to a wide clear top end, at both low and high playback levels, something that my present midfields didn’t do well.

I patiently gave my ears plenty of time to adjust and adapt to the MM 27′s. Over a period of a few months, I slowly weaned myself from my old midfields to the Barefoots. It wasn’t a deliberate decision, I just found myself over time being able to trust them. I’ve really fallen love with the bottom end they pump out and my mixes are coming out great. And for the benefit of clients that want to playback a mix at physically altering levels, unlike many other self-powered monitors, these can be driven really loud without the amp folding or going into an auto-limiting mode.

The most obvious response has been coming from my clients that prefer I playback on the Barefoots when making comments.

The final and most important factor in deciding to continue with the Barefoots came from Mastering. The first record that I recently mixed (Slow Poison/The Bravery) on the MM27′s got excellent reviews from my mastering engineer, meaning he didn’t have to mess with it and the bottom end was just right. Barefoots DON’T LIE!
