3.De fleste forstærkere leverer præcist den samme mængde effekt brokoblet med en belastning på 4 ohm, som de gør, når de driver en stereoudgang på 2 ohm.

Når du konstruerer et subwoofer-system, der maksimerer den tilgængelige forstærkereffekt, skal du huske på følgende regler:

MS-10SD2 SLIM, MS-10SD4 SLIM specifications

JBL, a renowned name in the audio industry, has introduced its remarkably designed subwoofers—the JBL MS-10SD4 SLIM and MS-10SD2 SLIM. These models are engineered to impress audiophiles and casual listeners alike with their compact size and powerful performance, making them suitable for a variety of vehicle audio systems.

The JBL MS-10SD4 SLIM subwoofer features a dual 4-ohm voice coil configuration, while the MS-10SD2 SLIM comes with a dual 2-ohm voice coil setup. This flexibility in voice coil impedance allows users to tailor their systems for optimum performance, achieving high-quality sound with various amplifier configurations. Both models are designed to deliver deep, rich bass, thanks to advanced sound engineering that maximizes the acoustic output.

One of the standout characteristics of the MS-10SD series is its slim profile. Measuring significantly less in height compared to traditional subwoofers, these models are perfect for vehicles with limited space, without compromising sound quality. This slim design enables easy installation under seats or in tight corners, making them ideal for compact cars or trucks.

The subwoofers are equipped with a robust thermoplastic compound cone that provides durability and excellent sound reproduction. This material not only enhances the longevity of the subwoofer but also ensures that the bass remains tight and punchy, whether you're blasting your favorite tunes or enjoying the subtle nuances of a movie soundtrack.

Moreover, the JBL MS-10SD SLIM series employs a high-temperature voice coil, ensuring resilience even during prolonged use at high power levels. This feature effectively prevents overheating, allowing users to enjoy their audio experience without interruptions. The models also include a custom-designed rubber surround that aids in reducing distortion, enhancing clarity across all frequencies.

Another innovative technology present in these subwoofers is the powerful magnet system that provides a strong magnetic field, enhancing efficiency and output. This design element ensures that the JBL MS-10SD4 and MS-10SD2 work seamlessly with various amplifiers, ensuring a dynamic audio performance that elevates any audio system.

In conclusion, the JBL MS-10SD4 SLIM and MS-10SD2 SLIM subwoofers offer an excellent combination of compact design, powerful performance, and advanced technologies. With their high-quality construction and innovative features, they promise an enhanced audio experience, making them a top choice for anyone seeking to elevate their in-car sound system while maintaining space efficiency.
