Thanks to the large diaphragm area of 829.6 cm² and the effective ventilation of the motor, precise bass reproduction with minimal distortion is achieved. Particularly noteworthy is the sensitivity of 91.2 dB @ 2.83V/1m, which ensures powerful sound reproduction that supports even demanding audio applications. Additionally, the subwoofer impresses with a frequency response of 18 - 800 Hz and the resulting broadband sound quality, which impressively represents both low and mid frequencies.

Welche Materialien werden beim Reference RSS390HF-4 verwendet?

The Dayton Audio Reference RSS390HF-4 is made of high-quality, black anodized aluminum for the cone, giving it impressive stiffness and low moving mass. The subwoofer also uses a cast aluminum basket, which increases its structural integrity while improving sound quality. The voice coil wire is made of copper, providing excellent electrical conductivity, while the material of the voice coil former is also made of aluminum. The magnetic component is made of ferrite, and the surround material is rubber, ensuring lasting flexibility and durability.

Wie wirken sich die technischen Parameter des Dayton Audio Reference RSS390HF-4 auf die Klangqualität aus?

The sound quality of the Dayton Audio Reference RSS390HF-4 significantly benefits from its carefully tuned technical parameters. The resonance frequency of 19.5 Hz allows for deep bass reproduction, while the Qms parameter of 3.02 indicates that mechanical losses are minimal. The electrical quality Qes of 0.50 and the total value Qts of 0.43 signal high efficiency and controlled, precise bass. The moving mass of 306 g and the compliance of the suspension of 0.22 mm/N support a smooth sound. Together with the maximum deflection of 14 mm, a dynamic audio reproduction is achieved that reproduces every note in detail.

Welche Gehäusearten eignen sich für den Einbau des RSS390HF-4 Subwoofers?

The Dayton Audio Reference RSS390HF-4 is versatile, as it is suitable for both sealed and vented enclosures. In sealed enclosures of about 81.55 liters, it offers an F3 of 37 Hz, which ensures concentrated and precise bass reproduction. For vented enclosures, a volume of 140 liters is recommended to achieve deeper bass reproduction, with an F3 of 21 Hz. This allows for a diverse adaptation to acoustic preferences and environments, enabling the subwoofer to be optimally integrated into both home theater applications and music systems.

Welche Abmessungen und Spezifikationen sind bei der Installation des Dayton Audio RSS390HF-4 zu beachten?

When installing the Dayton Audio Reference RSS390HF-4, its dimensions are crucial. The outer diameter is 388.4 mm, while the cutout diameter is measured at 355.8 mm, which must be taken into account when fitting into enclosures. The total depth of 178 mm allows for sufficient space inside the enclosure, and care should be taken with the positioning of the mounting holes (eight in total). Additionally, the weight of the magnet at 150 oz is an aspect that should be considered in the enclosure design to ensure stable mounting and optimal audio performance.

Welche Vorteile bietet der 2-lagige Schwingspuleneinsatz beim Dayton Audio RSS390HF-4?

The 2-layer voice coil of the Dayton Audio Reference RSS390HF-4 offers significant advantages in reducing back-EMF, ensuring cleaner and more accurate reproduction, especially at high volumes. This design helps improve the impulse fidelity of the subwoofer, which is important for demanding musical pieces. The effectiveness achieved allows for clear sound even in dynamic passages, while the structurally solid aluminum construction ensures maximum thermal dissipation to guarantee the longevity of the subwoofer even under intense use.

Wie beeinflusst der schwarz eloxierte Aluminiumkonus die Performance des RSS390HF-4?

The black anodized aluminum cone of the Dayton Audio Reference RSS390HF-4 is central to its sound performance. The stiffness of the material reduces distortions that can occur with conventional cone materials. The lower weight decreases the moving mass, leading to faster response times and clearer bass reproduction. These characteristics help ensure that deep and complex bass notes are reproduced with precision, without losing sound details. This enables an overall convincing audio playback not only in theoretical applications but also in realistic listening environments.

Welche Thiele Small Parameter sind für den Dayton Audio RSS390HF-4 charakteristisch?

The Thiele Small parameters that characterize the Dayton Audio Reference RSS390HF-4 illustrate its tuned performance. The resonance frequency (Fs) of 19.5 Hz indicates deep efficiency, while the total quality factor (Qts) of 0.43 represents a balance between sensitivity and frequency response. The moving mass (mms) is 306g and, together with the compliance (Cms) of 0.22 mm/N, influences the dynamic properties that the speaker offers. The force factor (BL) is 15 Tm, indicating strong drive and high precision. These factors together guarantee an optimal sound profile for various application fields.

Wie reduzieren die dreifachen Kurzschlussringe Verzerrungen beim Dayton Audio RSS390HF-4?

The triple short-circuit rings of the Dayton Audio Reference RSS390HF-4 significantly contribute to distortion minimization. These rings act as dynamic energy dissipation systems that reduce the inductive peaks during the movement of the voice coil. This optimizes the linearity of the magnetic field in the air gap, leading to a more accurate impulse response and thus to pure sound reproduction. The more effective magnetic control also contributes to heat dissipation, which in turn improves thermal stability. The combination of these effects ensures that even at high power output, the sound of the subwoofer remains exceptionally clear and low in distortion.

Wie ist die Kompatibilität des RSS390HF-4 mit Automarken oder Modellen?

The Dayton Audio Reference RSS390HF-4 can be used in different vehicle models due to its flexible enclosure compatibility. Before installation, the available space size in the vehicle should be checked, as the outer diameter of 388.4 mm and the total depth of 178 mm are the primary factors for the decision. However, due to its generous dimensions, this 15-inch subwoofer may not fit in smaller vehicle types. It is recommended to use a suitable enclosure to optimally maximize acoustic performance. This will require model-specific installation or adaptation to the vehicle's acoustics.
