Genelec W371AM SAM™ Woofer System (Black)

Full-Range Monitoring Extension for Genelec The Ones
The Genelec W371AM in black finish is a Smart Active Woofer System engineered to extend the low-frequency capabilities of Genelec’s 8341A, 8351B, and 8361A coaxial nearfield monitors. Unlike traditional subwoofers, the W371AM is designed to integrate as a full-bandwidth, directional low-frequency extension. It adds precision, depth, and control in the critical bass region, transforming nearfield monitors into full-range, point-source systems optimized for high-end music production, mastering, and post environments.

Dual 400W Woofers for Steerable Low-Frequency Performance
The W371AM houses two independently powered 400W woofers—one forward-firing in a sealed enclosure and one rear-firing in a bass-reflex design. This configuration allows the system to operate in three selectable directivity modes: Complementary for linear response, Directive for uniform dispersion, and Null-Steering to reduce boundary reflections. These options give users full control over how low-end energy interacts with the room, ensuring accurate, phase-coherent bass at any listening position.

Precision Monitoring in Challenging Acoustic Environments
Engineered for accurate monitoring even in less-than-ideal rooms, the W371AM adapts its behavior based on room layout, speaker placement, and listening position. The system enables transparent low-end reproduction without relying solely on acoustic treatment. When used in larger production spaces or control rooms with complex reflections, its steerable directivity makes it easier to maintain mix consistency across different environments.

Seamless Integration with GLM Calibration Software
The W371AM integrates tightly with Genelec’s GLM (Loudspeaker Manager) software, using room measurements to calibrate system response. Once paired with The Ones, GLM aligns phase, delay, and frequency response between monitors and woofers, allowing them to behave as a single full-range unit. This ensures that every decision made in the mix room will translate reliably to other systems and playback environments.

Flexible Input and Signal Routing Options
Analog and AES/EBU digital XLR I/O provide flexible routing for stereo and multichannel setups. An integrated 110-ohm digital loop-through enables daisy-chaining within a calibrated GLM network. Whether you work in analog, digital, or hybrid workflows, the W371AM accommodates the signal path without introducing unnecessary complexity.

Built to Extend Nearfields into Full-Bandwidth Systems
Designed to complement The Ones without compromising coherence or imaging, the W371AM supports large-format listening environments where nearfields alone are insufficient. It extends the system's usable frequency response down to 25 Hz and expands dynamic headroom while preserving tight time alignment and a single acoustic source image. Ideal for stereo or immersive setups, it enhances both spatial accuracy and bass articulation.

Includes Accessories for Immediate GLM Network Deployment
The W371AM ships with everything needed for GLM-based tuning, including the GLM User Kit, GLM network cable, and power cord. Setup is fast and repeatable, with automatic calibration tools built into the system. The clean black finish ensures that the system fits seamlessly into any modern studio aesthetic.
