Experience Full Range Power And Precision With The Barefoot Sound MicroStack45 3-Way Active Reference Monitors and Stereo Subwoofers

With the recent introduction of Barefoot Sound's MicroSub45 Dual-Force technology subwoofer, you can create MicroStack45, a stereo package of two MicroMain45 3-way active reference monitors and two MicroSub45 subwoofers. Each stereo system incorporates a pair of 1-inch tweeters, four 2.5-inch midrange drivers, and six high-excursion 8-inch woofers, all designed to work seamlessly together and as a single unit.

Dual-Force Low-Frequency Extension

MicroSub45 subwoofers feature Barefoot's innovative Dual-Force technology, housing a pair of opposing 8-inch aluminum cone drivers plus a balanced analog high-pass filter that crosses the system over at 80 Hz. Dual-Force technology eliminates vibration within the MicroSub45 speaker cabinet, delivering clean low-frequency extension down to 25 Hz when combined with the MicroMain45.

Stacks and Tilts

Barefoot Sound's MicroStack45 system works optimally when the MicroMain45 monitors are positioned either directly on top of or underneath the MicroSub45 subwoofers, depending on your preference. A tilt feature enables the MicroMain45 monitors to be directed at the listening sweet spot and is designed so that the stack is very sturdy and will not slip.

If you are working to a budget, you can start with a stereo pair of MicroMain45 monitors then add two MicroSub45 subwoofers when the time is right.

MEME Technology

Barefoot Sound's Multi-Emphasis Monitor Emulation technology harnesses sophisticated DSP modeling to bring you the voicing characteristics and responses of classic studio nearfield monitors. You can use the four-position wired remote to quickly switch through different voices, allowing you to preview your mix on different types of speakers, from the same stereo position and without the clutter of multiple speaker systems.

The four settings are "Old School," "Cube," "Hi-Fi," and "Flat." The "Old School" setting captures the essence of the ubiquitous NS10M, rolling off the sub-bass and top-end information, and bringing forward mid-range presence. The "Cube" setting is a nod to the "aura" of the classic full-range micro monitors of yesteryear, a valuable setting in the age of laptops, tablets, and earbuds. "Hi-Fi" sweetens the high end and warms mid-range to behave much like consumer hi-fi systems, the perfect setting for quick artist playback or when listening to favorites in the studio. Last, as you might expect, "Flat" is the prized default setting, offering the true, revealing Barefoot Sound.
