The smallest of "The Ones"

The Genelec 8331 AP is the smallest model in the "The Ones" series, in which the Finnish manufacturer focuses on active three-way studio monitors with a coaxial design. This construction offers not only extremely precise imaging and a wide sweet spot, but also very compact dimensions. In fact, the 8331 AP is closer in size to a compact two-way system, yet it is packed with advanced digital technology. Whether used in stereo operation or in larger immersive formats, multiple monitors can be networked and controlled via the accompanying GLM software (Genelec Loudspeaker Manager). The separately available GLM set, consisting of a network adapter and a measurement microphone, enables automatic calibration of the speakers using DSP-based SAM technology (Smart Active Monitor).

Intelligent design

The studio monitors in Genelec's "The Ones" series combine a coaxial midrange and tweeter unit with two oval woofers, which are concealed behind the front baffle that incorporates a large waveguide. The two woofers are positioned symmetrically around the coaxial element and behave acoustically like a single large woofer. As the smallest model in the series, the 8331 AP delivers a total output power of 144W, provided by three Class D amplifiers for the bass (72W), midrange (36W), and tweeter (36W). With a maximum output of 104dB SPL and a frequency response of 58Hz to 20kHz (at +/-1.5dB), the 8331 AP offers impressive performance for such a compact monitor. An adjustable IsoPod for horizontal and vertical placement is included in the scope of delivery. Suitable wall or ceiling mounts and stand adapters are available separately.

Networked monitoring system

The Genelec 8331 AP is an excellent choice for professional users seeking a highly compact, extremely precise three-way nearfield monitor. With its remarkably small dimensions of just 305 × 189 × 212 mm, the individually sold 8331 AP is ideal not only for smaller control rooms but also for mobile applications. In theory, up to 80 speakers can be networked using the supplied RJ45 cables. The accompanying GLM software ensures that the entire system is adapted to the acoustics of the respective room (GLM set required), aligning level, frequency response, and time-of-flight differences. Alternatively, a simpler set of sound controls is available at the rear of the device for operation without software or networking.

About Genelec

Genelec was founded in 1976 by Ilpo Martikainen. It grew from a family business into one of the world's leading manufacturers of professional studio and broadcasting loudspeakers. To this day, Genelec's loudspeakers are manufactured exclusively in Finland. Genelec offers performance-oriented, neutral-sounding loudspeakers and subwoofer systems for audio professionals and sound enthusiasts, and a combination of innovative technology and design ensure that the range of products is continuously improving. The company is committed to sustainable development and environmental awareness. In 2018, Genelec was awarded the Pro Sound "Company of the Year" award. Genelec speakers are favourites of such recording industry veterans as Obie O'Brien, Michael Carnes, and David Reitzas, as well as of producers like Hardwell, Keith Ross, and Vini Vici.

Ideal for constructing immersive systems

Genelec's "The Ones" series uses a sophisticated internal DSP system for filters, limiters, and further signal processing. The XLR input of the Genelec 8331 AP can be switched between analogue input and AES/EBU digital input, with the latter supporting resolutions of up to 192kHz. In addition, a purely digital AES/EBU output is provided at the rear of the device to loop the signal to additional speakers. The Genelec 8331 AP pairs perfectly with a digital subwoofer from the 7300 series. For larger immersive monitoring systems, multiple 8331 AP monitors can, for example, be combined with several 8330 two-way monitors used as surround or overhead speakers.

This is an outstanding sound!

Jack Back 08.02.2020

I was very worried about the lack of bass, as they are quite small, I was wrong, you will not feel the lack of bass. Thanks to them, it became much easier and faster to mix. The stereo picture is just as impressive, as well as a very large sweet spot. Build and packaging quality is very good. They fully justify their price!

Compact and phenomenal

jameslum 27.06.2021

I bought a pair and mounted them with 8000-323B table stands on my desk in a small room.

After calibration with a GLM kit, it made a huge difference. Although my room has poor acoustics, they manage to deliver an exceptional imaging and detailed soundstage. Proper room treatment is still needed to get the best performance though.

As small drivers have their limit, I would consider adding a subwoofer for better bass extension.

Fantastic monitors

Maciej R. 08.12.2025

Those are great, honest and very high quality monitors. Don’t buy them without GLM kit (room acoustic correction), the improvements to sound are significant. They have literally zero self noise and both analog and AES/EBU inputs with pass through. I saved long time to buy those, but they were worth every penny.
