Barefoot Sound LFE15 Dual 15" Subwoofer

Product Description

The Barefoot Sound LFE15 is a dual 15-inch active subwoofer featuring an innovative Dual-Force driver configuration that delivers powerful, extended bass for stereo setups as well as surround and immersive audio systems. Barefoot Sound's Dual-Force technology mechanically locks the opposing driver motors together, minimizing cabinet vibrations for smooth, uncolored bass response. Powered by a 1,400-watt amplifier, the LFE15 subwoofer extends low frequencies all the way down to 15 Hz. Choose between two modes, depending on your needs: LFE Mode for a dedicated low-frequency effects channel in a surround or Dolby Atmos setup, or Boost Mode for powerful low-end extension in standard stereo setups. Either way, the LFE15 subwoofer delivers deep, accurate bass that helps your mixes translate better. Read on to find out how the Barefoot Sound LFE15 can elevate your work in stereo, surround, or immersive formats.

PAIRS WITH ANY BAREFOOT SOUND MONITOR

Barefoot Sound designed the LFE15 subwoofer for seamless integration with all Barefoot monitors, including the Footprint, MicroMain, and MiniMain Series. In Barefoot Sound's 7.1.4 Dolby Atmos example, a single Barefoot LFE15 is paired with a combination of MicroMain27 and MicroMain26 front monitors with eight Footprint01 surround and ceiling speakers. For bigger rooms or larger formats such as 9.2.4, two Barefoot Sound LFE15 subwoofers can be run in mono or stereo. Whether you're expanding a Barefoot surround system or building a brand-new immersive audio room around Barefoot monitors, the Barefoot Sound LFE15 delivers powerful yet transparent low-frequency extension.

DUAL-FORCE TECHNOLOGY

At the heart of the LFE15 subwoofer is Barefoot's signature Dual-Force technology. The Barefoot LFE15's two Dual-Force drivers sit on opposite sides of the cabinet with their motors locked together, so their internal forces cancel each other out rather than transmitting to the cabinet itself, which can affect sound quality. This design eliminates cabinet vibrations at the source, removing a major cause of distortion and coloration. Because bass wavelengths are far larger than the subwoofer cabinet, the two drivers act as a single point source with greater accuracy than many single-driver designs.

TWO MODES OF OPERATION

The Barefoot Sound LFE15 subwoofer offers two modes of operation, making the LFE15 equally at home in immersive and stereo setups. LFE Mode configures the subwoofer as a dedicated low-frequency effects channel for surround and Dolby Atmos playback. Boost Mode turns it into a low-frequency enhancement channel that works alongside a stereo pair to augment stereo monitors with deeper, more powerful bass. A front-panel switch selects the mode, and the gain and filter controls fine-tune its behavior. This flexibility means the LFE15 keeps up with your evolving setup, from a stereo system all the way to an immersive audio setup.

LFE MODE

In LFE Mode, the Barefoot Sound LFE15 functions as the low-frequency effects channel in a surround system, reproducing the dedicated .1 channel in formats from 5.1 to 7.1.4. In this mode, the LFE15 engages a fourth-order Butterworth low-pass filter with a selectable cutoff frequency of 80 Hz or 120 Hz. The steep filter slope provides a defined cutoff, keeping frequencies above the selected crossover point from reaching the subwoofer. With Dual-Force bass response down to 15 Hz and up to 130 dB peak SPL, LFE Mode provides an impactful low-frequency effects channel for post-production and immersive mixing.

BOOST MODE

Boost Mode is designed for stereo setups where you want the LFE15 to add deeper, fuller low frequencies to your main monitors. A first-order Butterworth low-pass filter with selectable 60 Hz and 80 Hz settings rolls off gently, helping minimize phase cancellation near the cutoff frequency when the subwoofer combines with the stereo pair. In Boost Mode, the LFE15 supplements the full-range output of your main monitors, adding low-frequency weight without requiring a traditional high-pass filter.

CONNECTIVITY

Barefoot kept connectivity simple on the LFE15 so it can seamlessly integrate with any setup. Two balanced XLR inputs on the subwoofer accept analog line-level signals from monitor controllers, audio interfaces, or mixing consoles. The inputs sum together, so you can feed left and right channels for Boost Mode or route a single LFE input signal into either input for LFE Mode. Two XLR outputs pass the incoming signal through, letting you send it to another Barefoot LFE15 subwoofer without a separate splitter.

CONTROLS

The Barefoot Sound LFE15 provides a focused set of controls that make subwoofer calibration quick and repeatable. The LFE Gain selector adds +10 dB of input gain to the LFE15 in either mode, matching the standard LFE sensitivity used in Dolby Atmos and surround playback for extra headroom on the LFE channel. The LPF control sets the Barefoot Sound LFE15's low-pass filter frequency, with the low-pass filter selectable at 80 Hz or 120 Hz in LFE Mode, and 60 Hz or 80 Hz in Boost Mode, so the subwoofer's bass frequencies blend smoothly with your mains for an accurate frequency response. An included remote footswitch mutes or engages the LFE15 subwoofer with a tap of the pedal, letting you make instant A/B comparisons.
