LFE12 Subwoofer

Dual-Force Technology
Two opposing woofers work together to cancel mechanical forces, reducing cabinet vibration and unwanted resonance for cleaner, more controlled bass reproduction.

Dual 12-Inch Aluminum-Cone Woofers
Two large woofers with neodymium motor structures deliver powerful low-frequency output with excellent definition and transient response.

1400W Amplification
A powerful internal amplification system provides the output and headroom required for demanding professional monitoring applications.

Extended Low-Frequency Response
Reproduces deep bass down to 17 Hz, providing the low-frequency extension needed for accurate mixing, mastering, and immersive audio production.

Dedicated LFE Mode
A separate LFE input reproduces discrete low-frequency effects channels in surround and immersive monitoring systems.

Stereo BOOST Mode
Extends the low-frequency response of connected stereo monitors while preserving their full-bandwidth signal path.

Independent LFE and BOOST Operation
Both modes can operate simultaneously, providing flexible low-frequency support for stereo and multichannel monitoring.

Dual-Switch Foot Controller
Independently engage or mute LFE and BOOST signals for quick, hands-free comparisons during monitoring sessions.

Selectable Low-Pass Filters
Dedicated filter settings for LFE and BOOST modes allow precise control over low-frequency integration with the main monitors.

Stepped Input Level Control
An eight-position rotary control provides precise, repeatable level adjustments for matching the subwoofer to the monitoring system.

Switchable Input Gain
Selectable gain settings accommodate different signal levels and monitoring requirements.

Balanced XLR Connectivity
Dedicated LFE and stereo inputs provide reliable connections to monitor controllers, audio interfaces, and other professional equipment.

Full-Bandwidth THRU Outputs
Pass the complete stereo signal to connected Footprint monitors without filtering their main audio path.

Sealed, Acoustically Damped Cabinet
Rigid enclosure construction and internal damping help minimize unwanted resonances and maintain accurate low-frequency reproduction.

Footprint Series Integration
Purpose-built to complement Barefoot Sound Footprint01, Footprint02, Footprint03, and Footprint03C monitors in stereo, surround, and immersive configurations.
