Barefoot Sound MicroSub45 Dual-Force Subwoofers (Pair)

The Barefoot Sound MicroSub45 is purpose-built to extend the low-frequency performance of the MicroMain45 system, adding depth, authority, and headroom without compromising accuracy. Designed as a matched stereo pair, MicroSub45 integrates seamlessly into Barefoot monitoring environments, delivering controlled, musical bass extension for mixing, mastering, and immersive workflows.

Designed for the MicroMain45 System

MicroSub45 was engineered specifically to complement the MicroMain45 nearfield monitor. Each cabinet houses dual opposing 8-inch woofers and delivers clean, extended low end down to 25 Hz. An analog high-pass filter crosses over at 80 Hz, relieving the MicroMain45 of low-frequency energy and increasing overall system headroom while maintaining tight phase alignment and accurate translation.

• Designed to integrate directly with MicroMain45 monitors.
• Extends low-frequency response down to 25 Hz.
• Analog 80 Hz balanced high-pass crossover.
• Increases system headroom and low-end clarity.

Dual-Force Low-Frequency Control

At the core of MicroSub45 is Barefoot’s Dual-Force design, using opposing woofers to cancel cabinet vibration at the source. By mechanically coupling the motors and driving the cones in opposite directions, distortion and enclosure coloration are minimized, resulting in powerful, controlled bass that remains accurate even at high output levels.

• Dual opposing 8-inch aluminum cone subwoofers per cabinet.
• Mechanical force cancellation for reduced vibration.
• Clean, tight low-frequency reproduction.

High-Power Performance

Each MicroSub45 cabinet delivers 500 watts of amplification, providing the energy needed for deep, dynamic bass without compression or strain. This power reserve ensures consistent low-frequency performance across long sessions and demanding playback levels, whether in stereo or immersive monitoring setups.

• 500 watts of amplification per cabinet.
• 1000 watts total system power (pair).
• Sealed enclosure for accurate transient response.

MicroStack45 System Compatibility

MicroSub45 subwoofers are also available as part of the MicroStack45 system, combining MicroMain45 monitors and MicroSub45 subwoofers into a complete full-range monitoring solution. This modular approach allows studios to scale their monitoring systems as needs evolve while maintaining consistent sonic performance.
