Frequent questions about VO-MN308


Welche technischen Merkmale hat der DD Audio VO-MN308?

The DD Audio VO-MN308 is an 8-inch neodymium midrange driver equipped with a double neodymium magnet structure. The power rating is 200 watts RMS at an impedance of 4 ohms. The voice coil, with a diameter of 38.1 mm, is copper-coated and wound on a Kapton vented former, which improves heat dissipation. Special highlights include the ultra-light long-fiber pulp diaphragm and the neodymium main magnet ring, which help produce precise sound details with a sound pressure level of 97 dB. The frequency range is between 100 Hz and 14 kHz, ideal for high-quality audio applications.

Wie sieht die Installationskompatibilität des VO-MN308 aus?

The installation diameter of the VO-MN308 is 181 mm, while the installation depth measures 86 mm. These dimensions allow for a variety of installation options in common car audio setups, provided there is sufficient installation depth. The speaker is compatible with installations that support a midrange driver design with similar dimensions. Special attention should be paid to the installation opening to ensure that no bottlenecks hinder integration into the existing sound system. For vehicle models with limited installation space, compatibility should be checked before installation to ensure a hassle-free setup.

Was ist die Resonanzfrequenz des VO-MN308?

The resonance frequency of the VO-MN308 is 102 Hz. This frequency is a critical parameter that marks the point at which the mechanical impedance of the speaker is at its lowest. This allows the speaker to effectively transmit vibrations, with the design of the neodymium main magnet ring and the kapton-vented voice coil being essential elements to support high performance at this specific frequency. The resonance frequency value is also an indicator of the suitability of the VO-MN308 in broadband audio playback applications and significantly influences the overall sound profile.

Wie beeinflusst die ultraleichte Langfaser-Zellstoffmembran den Klang des VO-MN308?

The ultra-light long-fiber pulp membrane of the VO-MN308 significantly contributes to the outstanding sound quality. Due to its low mass, this membrane allows for a fast and precise response to electrical input signals, resulting in accurate sound details. The treatment of this type of membrane maximizes both sensitivity and responsiveness in the covered frequency range of 100 Hz to 14 kHz. The integration with the neodymium main magnet ring ensures that a consistent and low-distortion audio experience is guaranteed, even at high sound pressure levels such as the impressive 97 dB of the VO-MN308.

Warum ist der Schalldruckpegel des VO-MN308 wichtig?

The sound pressure level of the VO-MN308 is 97 dB, indicating the high efficiency of the speaker. A higher sound pressure level means that the speaker can emit more sound energy at the same power, which is particularly advantageous when you listen to music in louder environments. The high efficiency of the neodymium magnet combined with the lightweight cellulose membrane ensures dynamic and powerful sound reproduction. The sound pressure level is a crucial factor in understanding the performance of the speaker, especially when it is installed in a car audio system, where sufficient volume is required to effectively fill the vehicle's interior with sound.

Welche Rolle spielt die Schwingspule im VO-MN308?

The copper-coated aluminum voice coil of the VO-MN308, with a diameter of 38.1 mm, is a central element for sound reproduction. This voice coil ensures efficient conversion of electrical energy into mechanical movement. The use of copper-coated aluminum combines the good heat dissipation properties of copper with the lightweight construction of aluminum, both of which contribute to increased performance. In conjunction with a kapton-vented coil carrier, this maximizes thermal stability, which is important for consistent performance even under high loads. Thus, reliability is ensured even during longer music sessions.

Was bedeutet der Qts-Wert beim VO-MN308?

The total quality factor (Qts) of the VO-MN308 is 0.55. This value provides indications of the suitability of the speaker for various enclosure types in audio technology, whether in closed or bass reflex enclosures. A Qts value around 0.5 suggests a more flexible usability in different acoustic environments without compromising sound quality. The Qts is a theoretical value calculated from the electrical (Qes = 0.57) and mechanical quality factors (Qms = 11.96), and it influences the transfer behavior in the frequency range near the resonance frequency. Thus, the VO-MN308 delivers balanced sound characteristics, ideal for many applications.

In welchem Frequenzbereich arbeitet der VO-MN308?

The frequency range of the VO-MN308 extends from 100 Hz to 14 kHz. Within this spectrum, it delivers exceptional sound fidelity across a wide range, which is crucial for a midrange driver to cover both the lower mids and part of the high frequencies. The bandwidth is achieved through the sophisticated design of the ultra-lightweight cellulose diaphragm and the strong neodymium magnet ring in conjunction with the advanced voice coil. This makes the VO-MN308 versatile, suitable for powerful music basses as well as detailed highs, ideal for enthusiastic audio lovers who prefer a seamless sound image.

Welche Materialien werden im VO-MN308 verwendet?

High-quality materials in the VO-MN308 guarantee its performance. A treated long-fiber paper membrane, together with the fabric surround, ensures dynamic reproduction and robustness. The neodymium ring and the copper-coated aluminum voice coil wire optimize the magnetic flux density and reduce inductance and distortion. The Kapton-vented coil carrier provides additional thermal stability. This material mix maximizes the efficiency and bandwidth of the midrange driver, resulting in improved sound quality. These carefully selected components are crucial for ensuring long-lasting and highly accurate audio reproduction.

Welche Einfluss hat der Neodym-Hauptmagnetring im VO-MN308?

The neodymium main magnet ring used in the VO-MN308 is fundamental to the high efficiency and performance of the speaker. Neodymium is known for its strong magnetic properties, which provide higher energy in a smaller volume compared to conventional ferrite magnets. This allows for a compact design without loss of power. The neodymium magnet in the VO-MN308 helps minimize distortion and improves electromagnetic efficiency. In combination with Faraday short-circuit rings that reduce inductance, this design offers optimized sound reproduction with a precise and clear audio profile across the entire frequency range.
