Genelec 8351BM 8.5" 3-Way Smart Active Studio Monitor

Advanced Three-Way Monitoring with Upgraded Driver Technology
The Genelec 8351BM is a high-performance Smart Active Monitor built for nearfield and midfield applications in professional audio environments. Featuring an upgraded tweeter, refined amplifier performance, and Genelec’s powerful SAM (Smart Active Monitoring) technology, the 8351BM delivers uncolored, phase-accurate sound with wide dynamic range and pinpoint imaging. Housed in a sleek black finish, this three-way point source monitor is designed to perform in studios, edit bays, mastering suites, and immersive setups where reliable audio translation and consistent monitoring are critical.

Coaxial Mid and High Frequencies for Accurate Imaging
At the core of the 8351BM is Genelec’s proprietary Minimum Diffraction Coaxial (MDC) driver, which aligns the 5" midrange and ¾" tweeter into a single coherent point source. This coaxial design eliminates phase discrepancies between drivers and maintains uniform response across the entire listening field. The result is precise stereo imaging and consistent tonal balance across on-axis and off-axis positions—ideal for professionals working in spatial audio or multichannel formats.

Acoustically Concealed Woofers for Extended Low-End Clarity
The dual 8.5" Acoustically Concealed Woofers (ACW) are positioned behind the Directivity Control Waveguide and radiate through side apertures. This design keeps the front baffle clean and symmetrical while producing accurate low-frequency extension down to 38 Hz. The ACW system, paired with a reflex port, provides efficient bass output and reduces distortion at high SPL—delivering the low-end precision needed for mixing, mastering, or evaluating sub-heavy content.

Directivity Control Waveguide for Wide, Consistent Dispersion
Genelec’s Directivity Control Waveguide (DCW) spans the entire front baffle and integrates with the coaxial driver and concealed woofers to produce controlled dispersion across the frequency range. This minimizes early reflections and widens the listening sweet spot, making the 8351BM effective in various room sizes and configurations—whether you’re seated at a console, moving within the mix position, or collaborating with others in the control room.

Room-Adaptive Monitoring with GLM Calibration Software
The 8351BM is part of Genelec’s Smart Active Monitor family and works seamlessly with the GLM (Genelec Loudspeaker Manager) software. Using GLM, users can automatically calibrate the speaker system to the room, applying time alignment, EQ compensation, and level matching across stereo or multichannel formats. Whether you’re working in a treated environment or a less-than-ideal space, GLM ensures your monitoring remains accurate and translatable.

Flexible Connectivity and Standalone Control Options
The monitor accepts balanced analog and AES/EBU digital signals via XLR, with automatic switching based on signal presence through Intelligent Signal Sensing (ISS). Rear DIP switches provide manual control over input selection, channel routing, and output level for offline or fixed installations. An AES/EBU output is also included to daisy-chain digital signals to additional monitors, simplifying multi-monitor system configurations.

Studio-Ready Design with Iso-Pod and Versatile Mounting
The Minimum Diffraction Enclosure (MDE) offers reduced cabinet coloration and a modern look in an all-black finish. The included Iso-Pod stand decouples the speaker from reflective surfaces and allows vertical angle adjustment for precise monitor positioning. Horizontal or vertical orientation is fully supported without loss of acoustic performance, and multiple mounting options accommodate desktop, wall, or ceiling installations.
