Genelec G4AMM Active Bookshelf Speaker – Matte Black

The Genelec G4AMM Active Bookshelf Speaker in matte black is a premium two-way loudspeaker designed for audiophiles and home audio enthusiasts. Part of Genelec’s acclaimed G Series, this bi-amplified speaker merges professional-grade studio technology with a sleek, consumer-friendly design by Harri Koskinen. Ideal for stereo systems or home theater setups in medium to large rooms, the G4AMM delivers uncolored, dynamic sound with exceptional clarity.

Featuring a 6.5-inch woofer and 0.75-inch metal-dome tweeter, the G4AMM is powered by dual 90W Class-AB amplifiers (180W total), achieving a frequency response of 41 Hz to 25 kHz (-6 dB) and a maximum SPL of 105 dB. The 3 kHz crossover ensures seamless driver integration, while the Directivity Control Waveguide (DCW™) enhances off-axis dispersion for a wide, accurate sweet spot. The Minimum Diffraction Enclosure (MDE™), crafted from die-cast aluminum, reduces acoustic reflections, paired with a rear reflex port for deep, distortion-free bass.

Connectivity is versatile with XLR and RCA inputs (10 kOhm impedance), and the active design eliminates the need for external amps. Rear-panel controls include bass adjustment (0 to -6 dB), desktop control (-4 dB at 200 Hz), and treble tweaks for room optimization. The included Iso-Pod™ stand decouples vibrations and allows tilt adjustments, while the Autostart function saves power (0.5W standby).

Built in Finland, the G4AMM (365 x 237 x 223 mm, 8.6 kg) boasts a matte black finish, M6 mounting points, and a 5-year warranty (2+3 upon registration). Perfect for music, movies, or nearfield listening, it pairs seamlessly with Genelec F Series subwoofers for enhanced bass. The G4AMM embodies Genelec’s legacy of precision and durability since 1978.
