Genelec SAM 8331A Studio Monitor in Black

The Genelec 8331A SAM studio monitor is a compact three-way point source loudspeaker that delivers astonishing accuracy from a footprint usually reserved for small two-way designs. Part of Genelec’s acclaimed The Ones series, it combines Smart Active Monitoring technology with advanced coaxial driver engineering to give you mixes that translate, even in the tightest of spaces.

With a frequency response extending from 45 Hz up to 37 kHz and a maximum SPL of 104 dB, the 8331A offers full-range performance at short to medium listening distances. Whether you are working in stereo, multi-channel or immersive formats, its precise imaging, wide sweet spot and fatigue-free sound make it an exceptional choice for demanding professional studios, edit suites and mobile rigs where space and precision are critical.

Ultra-compact three-way point source design

The 8331A is the smallest model in The Ones family, yet it houses a full three-way system in an enclosure comparable to many compact two-way monitors. Genelec’s Minimum Diffraction Coaxial driver technology places the midrange and tweeter in a single point source, with concealed woofers handling the low end. This configuration delivers outstanding imaging and phase coherence, so you can hear placement, depth and detail in your mix with remarkable clarity, even at very close listening distances.

Smart Active Monitoring with GLM calibration

As part of the SAM range, the 8331A integrates seamlessly with Genelec Loudspeaker Manager (GLM) software. Using the optional GLM kit, you can automatically calibrate each monitor to your room, compensating for detrimental acoustics and distance delays. The system optimises level, timing and frequency response, helping you achieve consistent, reliable results whether you are working in a small project room, a post suite or a compact immersive setup.

Fatigue-free monitoring for long sessions

The combination of point source behaviour, controlled directivity and ultra-smooth frequency response makes the 8331A exceptionally easy on the ears. By minimising unnatural imaging and spectral anomalies, it reduces one of the main causes of listening fatigue. This allows you to work confidently for longer, make faster decisions and maintain perspective on your mix, even during extended sessions.

Powerful, precise amplification

Each driver in the 8331A is powered by its own dedicated Class D amplifier, with 72 W for the bass section, 36 W for the midrange and 36 W for the tweeter. This tri-amplified design ensures tight control, excellent transient response and plenty of clean headroom up to 104 dB SPL. The result is a monitor that remains composed and detailed at realistic working levels, revealing subtle dynamics and low-level information without strain.

• Three-way point source coaxial design - The Minimum Diffraction Coaxial driver places midrange and tweeter in a single acoustic centre, with hidden woofers completing the system. This delivers exceptional imaging, phase accuracy and a wide, stable sweet spot, so panning, reverb tails and spatial effects are easy to judge.
• Smart Active Monitoring with GLM - Built-in SAM technology works with Genelec Loudspeaker Manager software to analyse your room and automatically calibrate each monitor. By compensating for room colouration and distance delay, it helps your mixes translate more reliably between different playback systems.
• Compact footprint with full-range performance - With dimensions of just 305 x 189 x 212 mm (including Iso-Pod), the 8331A fits comfortably on crowded desks, meter bridges or tight edit suites while still offering a 45 Hz to 37 kHz frequency response and 104 dB SPL capability.
• Professional analogue and digital connectivity - XLR analogue and AES/EBU digital inputs, plus an AES/EBU output and dual RJ45 control ports, provide flexible integration into modern studio setups. This makes it straightforward to deploy the 8331A in stereo, multi-channel or immersive systems with precise digital routing and control.
