The MicroMain45 has turned into a cult speaker that musicians love. A common request from users since the release of the MicroMain45 is for Barefoot Sound to build a companion subwoofer. So Barefoot has built a subwoofer as an off-the-menu item. But as demands have been overwhelming, it’s time to bring this product into the light.

Introducing the MicroSub45 featuring Barefoot Sound’s innovative Dual-Force™ technology The MicroSub45 brings the MicroMain45 to new power and depths with a pair of dual-opposing 8” subs in each cabinet and Dual-Force™ Technology.

DUAL-FORCE™ Technology
The MicroMain45 is the only Barefoot that doesn’t feature Dual-Force™ Technology. But now there is a path for MicroMain45 users who want to take it to the next level. Or if you’re interested in a pair of MicroMain45s and want the option to upgrade down the road as your needs grow, this is the perfect solution!

It is recommended that the MicroSub45s are stacked on top or underneath the MicroMain45s, creating a “MicroStack45.”

The MicroMain45s can be placed on top or below the MicroSub45, depending on your preference. The tilt feature allows the MM45 to be positioned down to the listening sweet spot and it is designed so that the stack is very sturdy and will not slip.

The subwoofers is the MicroSub45s. When packaged with the MicroMain45s, it becomes the MicroStack45.  The stack features six high excursion 8” drivers, all designed to work seamlessly together and as a single unit.

Each MicroSub45 features analog crossovers which allows analog signal paths into the sub and also into the MicroMain45. It crosses over at 80hz and goes down to 25hz.

Similar to Barefoot’s flagship MasterStack12, The MicroStack45 is designed to work in stereo.
