Features of the JBL 2408H
High-Frequency Performance
The JBL 2408H is designed to excel in high-frequency sound reproduction. With a frequency response extending from 1.5 kHz to 20 kHz, it covers a broad spectrum of audio frequencies, ensuring detailed and accurate sound reproduction. The titanium diaphragm material enhances the driver’s durability and helps maintain sound clarity even at high volumes.
Power Handling and Sensitivity
With a power handling capacity of 75 watts RMS and a sensitivity rating of 107 dB, the JBL 2408H is capable of producing high output levels while maintaining efficiency. This power handling capacity allows the driver to perform reliably in demanding audio environments, such as concerts and large-scale events.
Neodymium Magnet
The use of a neodymium magnet in the JBL 2408H contributes to its high performance. Neodymium magnets are known for their strong magnetic fields relative to their size, which enhances the driver’s efficiency and helps reduce overall weight. This makes the JBL 2408H a more compact and lightweight option compared to drivers with traditional ferrite magnets.
Applications of the JBL 2408H
Professional Sound Reinforcement
The JBL 2408H is widely used in professional sound reinforcement systems. Its ability to handle high power levels and reproduce high-frequency sounds accurately makes it ideal for live sound applications. The driver is often found in high-end PA systems, stage monitors, and large-scale speaker arrays, where its performance contributes to clear and impactful sound delivery.
Studio Monitoring
In addition to live sound applications, the JBL 2408H is also used in studio monitoring setups. Its precise high-frequency response ensures that audio engineers and producers can hear details in their mixes with accuracy. This helps in making critical adjustments during the recording and mixing process, ultimately leading to a more polished final product.
Comparing the JBL 2408H to Other Drivers
JBL 2408H vs. JBL 2450J
When comparing the JBL 2408H to other compression drivers like the JBL 2450J, several differences emerge. The JBL 2408H is generally more compact and lightweight due to its neodymium magnet, which can be advantageous in applications where space and weight are constraints. The 2450J, on the other hand, offers higher power handling but is bulkier, making it better suited for larger sound systems.
JBL 2408H vs. JBL 2414H
Another comparison is with the JBL 2414H, which is also a popular compression driver. The JBL 2408H features a wider frequency response range and higher sensitivity, providing a more detailed high-frequency performance. The 2414H, while offering robust performance, may not match the extended high-frequency reach of the 2408H.
Maintenance and Care
Routine Inspection
To ensure the longevity and optimal performance of the JBL 2408H, regular maintenance is essential. Routine inspections should include checking the diaphragm for any signs of wear or damage and ensuring that the driver is clean and free from dust or debris.
Cleaning and Storage
When cleaning the JBL 2408H, use a soft, dry cloth to avoid damaging the diaphragm or other components. Store the driver in a dry, temperature-controlled environment to prevent exposure to moisture or extreme temperatures, which can affect performance and durability.
Conclusion
The JBL 2408H is a high-performance compression driver that excels in delivering clear and accurate high-frequency sound. Its impressive specifications, including a broad frequency response and high sensitivity, make it a valuable component in both live sound and studio environments. Whether you’re reinforcing sound at a large event or refining audio in a studio, the JBL 2408H provides reliability and precision. Have you experienced the exceptional sound quality of the JBL 2408H, or are there other audio components you’re interested in exploring?
