This component serves as a link between the diaphragm and the suspension, allowing movement while keeping the system stable. It absorbs unwanted vibrations and prevents negative feedback on the sound. The soft material allows the surround to respond flexibly, enabling the finest dynamics and ensuring high sound fidelity. For demanding audio applications, this detail is essential to achieve smooth and distortion-free sound projection.
The housing dimension of 58 mm of the Accuton BD30-6-458 facilitates integration into compact speaker designs and audio modifications. When installing in an existing audio system, it must be ensured that the available mounting opening can accommodate this dimension. A critical aspect is the precise fit to the mounting device to minimize vibrations. The moderate housing dimension allows for universal applicability in various applications, but it also affects the acoustic volume and baffle design. Before installation, it is important to check the installation depth and ensure adequate ventilation for optimal performance.
With the BD30-6-458, the robust diamond dome eliminates the need for a cutout in the dome, as the material is extremely stiff and strong. This property reduces mechanical weaknesses that could arise from punching holes in other materials. The entire structure becomes more stable and durable, without the risk of compromising quality. This design ensures that sound distribution across the dome remains even and does not provoke acoustic anomalies. Without the need to make structural compromises, a consistent and pure reproduction is achieved, ideal for audiophile environments.
The manufacturer-specific clamping technology of the BD30-6-458 tweeter ensures precise mounting and adaptability. This technology does not require special mounting frames, which facilitates installation. It is important to ensure mechanical stability by attaching the clamps evenly and with sufficient pressure. This prevents vibrations and ensures optimal acoustic contact with the baffle. Since no cutouts in the dome are necessary, the integration of the BD30-6-458 occurs without compromises in the cabinet construction and is compatible with most speaker designs that allow for unobtrusive integration.
The BD30-6-458 achieves impressively low distortion values, which are at 0.07% at 2.83 V and a maximum of 0.5% at a volume of 110 dB. These extremely low distortion values are a result of the underhung motor design and high-quality materials such as diamond dome, titanium frame, and neodymium magnets. The construction minimizes unwanted harmonic and intermodulation distortions, which is essential for the precise reproduction of audio signals. Thus, the sound remains uncolored and detailed even at high volumes, which is of utmost importance for sensitive high-end audio equipment.
The proprietary clamping technology in the Accuton BD30-6-458 allows for a flexible and stable attachment without the need for additional mounting frames or devices. This technology ensures a firm connection to the baffle and prevents unwanted movements that could cause disturbances. The clamping technology also guarantees a quick and easy installation, thereby reducing time and effort. The reassuring fixation improves mechanical stability during operation and ensures optimal energy transfer from the tweeter to the baffle, which is an integral part of distortion-free sound reproduction, especially in audiophile setups.
