Floor standing

The subwoofer is under normal conditions always placed directly on the floor. This is taken into account in the basic design and the basic settings of the AIR system.

Placement in the corner

This is a π/2 radiation, which yields a gain of 18 dB in the frequency range where the monitor is considered to be omni-directional.

Most standing waves have their maximum in the corners of the room. Especially if the room has a cubic or shoebox shape (the room having all walls in parallel). The placing of the subwoofer in the corner may cause uneven sound distribution of the bass.

The corner position is normally only preferred if all opposite surfaces in the room are not in parallel.

Adjacent to a wall

This is a π radiation, which yield a gain of 12 dB in the frequency range where the monitor is considered to be omni-directional.

This position adjacent to a wall is commonly used, and it can be OK, but it must be noticed that the subwoofer should neither be placed in the middle or in the quarter points between two sidewalls if these are in parallel.

(See pages 29-32 for the optimum positions with regard to standing waves.)

Free standing

This is a π radiation, which yield a gain of 6 dB in the frequency range where the monitor is considered to be omni-directional.

The free standing position is highly recommended in all cubic and shoebox shaped rooms.

In any case: Try to avoid placing the woofer on the half or quarter lines between walls.

Dynaudio, a company renowned for its high-fidelity audio products, has made significant strides in the field of professional monitoring through its PPM (Professional Precision Monitoring) series. Among the standout models in this series is the Dynaudio PMN (Professional Monitoring Nearfield), which has garnered attention for its outstanding sound quality, precise technical performance, and sophisticated design.

One of the key features of the Dynaudio PMN monitors is their advanced driver technology. Equipped with proprietary drivers, the PMN series employs custom-designed woofers and tweeters that deliver an incredibly accurate frequency response. The woofers utilize a lightweight diaphragm, ensuring that low frequencies are produced with power while maintaining clarity. The tweeters, known for their soft dome design, excel in reproducing high frequencies with exquisite detail and minimal distortion, making the listening experience both immersive and enjoyable.

In terms of design, the PMN monitors boast a sleek and modern aesthetic that fits seamlessly into any studio environment. The cabinet construction employs advanced materials and techniques that minimize resonance, thus reducing unwanted coloration in sound. The unique curved shape of the cabinets is not only visually appealing but also supports optimal acoustic performance by enhancing sound dispersion.

Another notable characteristic of the Dynaudio PMN is its versatility. The monitors are equipped with multiple inputs, allowing for seamless integration into various set-ups, whether in a professional studio or a home listening environment. This flexibility is further complemented by adjustable bass and treble controls, empowering users to tailor the sound profile to their specific requirements.

Dynaudio has also incorporated advanced technologies such as room correction in certain PMN models, which enables precise calibration according to the acoustics of the room. This feature ensures that audio professionals can rely on consistent and accurate sound reproduction regardless of their monitoring environment.

Overall, the Dynaudio PMN series represents a blend of pioneering audio technology, meticulous craftsmanship, and user-focused design. For professionals seeking precise monitoring solutions for music production, film scoring, or any audio-related projects, the Dynaudio PMN monitors provide an exceptional listening experience that stands the test of time. With their stellar performance and innovative features, these monitors have become a top choice for sound engineers, musicians, and audio enthusiasts alike.
