MEET MICROSTACK45Barefoot’s compact MicroStack45 stereo system comprises two MicroMain45 3-way active nearfield reference monitors and two MicroSub45 Dual-Force™ technology subwoofers. Each system combines six high-excursion 8-inch woofers, four 2.5-inch midrange drivers and two 1-inch tweeters working seamlessly together as a single unit driven by 2220W of power.The MicroMain45 distills the resolution and accuracy of the MiniMain12 into a compact, lighter and more cost-conscious package shares the same amplifier, driver technology and DSP as Barefoot’s flagship system. The MicroMain45’s no-compromise design combines an 8-inch aluminum woofer, two 2.5-inch aluminum midrange drivers and a 1-inch tweeter to deliver over 600W of power with a 40 Hz–45 kHz frequency response.The MicroSub45 houses a pair of opposing 8-inch Dual-Force™ technology woofers and an analog high-pass filter crossing over from the MicroMain45 at 80 Hz, delivering clean low-frequency extension down to 25 Hz. Dual-Force, a core technology that is found in almost every Barefoot product, eliminates vibration within the MicroSub45 speaker cabinet through its innovative force cancellation design. The opposing woofers significantly reduce distortion and coloration, add a massive internal metal cabinet brace and cause the subs to radiate as if they were a single point source located on axis with the tweeter.A sturdy, non-slip tilt feature directs the MicroMain45 monitors at the listening sweet spot.Current MicroMain45 owners can add a pair of MicroSub45 Dual-Force technology subwoofers to create a MicroStack45 system.Technical SpecificationsTechnical SpecificationsDescription: 3-way Active Reference Monitors and Stereo Subwoofers with MEME TechnologyControls: Input level stepped attenuator, Equalization contourInput Impedance: 50k OhmFrequency ResponseMicroMain45: 18Hz 50kHz (±3dB), 26Hz 40kHz (±1dB)Bass Response-3 dB: @ 25Hz, Q = 0.707Slope: 12 dB/octaveCabinetsInternal volume: 32 liters total togetherEnclosures: Both units are sealed woofer and midrange enclosuresBaffle plate: Machined aluminumDamping: Long fiber foam acoustic damping throughoutCrossover Frequencies: 80 / 600 / 3600 HzDriversTweeter: 1 ring radiator, Advanced geometry motor, Rear waveguide chamber.
