Product Description

Premium 18-Inch Subwoofer - Power & Precision in Every Bass Note Experience deep, thunderous bass with our high-performance 18-inch subwoofer, engineered for audiophiles, DJs, and home theater enthusiasts. Featuring a heavy-duty construction and advanced sound technology, this subwoofer delivers rich, distortion-free low frequencies that bring music and movies to life.

The dual-magnet design has various advantages in fields such as speakers, mainly including the following points:

 

Enhancing the magnetic field strength: Adopting the dual-magnet design is equivalent to increasing the number of magnets within the same space, which can effectively enhance the magnetic field strength. A stronger magnetic field can subject the voice coil to a greater force, thus causing the diaphragm to generate a larger displacement, improving the sensitivity of the speaker and making the sound louder and clearer.

 

Improving the sound quality performance: The dual-magnet design helps to improve the frequency response of the speaker, making the bass fuller and deeper, and the treble brighter and more delicate, thereby enhancing the overall sound quality. At the same time, the dual-magnet structure can better control the movement of the diaphragm, reducing distortion and making the sound more realistic and natural.

 

Increasing the heat dissipation capacity: In the dual-magnet design, a certain air gap will be formed between the two magnets, which is beneficial to air circulation and improves the heat dissipation effect. The voice coil generates heat during operation, and good heat dissipation can reduce the temperature of the voice coil, avoiding performance degradation or damage caused by overheating and extending the service life of the speaker.

 

Enhancing the power handling capacity: Due to the enhanced magnetic field of the dual-magnet design, the voice coil can withstand a larger current, thus improving the power handling capacity of the speaker. In this way, the speaker can handle a larger input power, maintain good sound quality even at high volumes, and meet the needs of users who have high requirements for both volume and sound quality.

Aluminum cones are widely used in speakers and have the following advantages:

 

Lightweight: Aluminum has a relatively low density, making the diaphragm of aluminum cone speakers relatively light in weight. According to Newton's second law F=ma, under the same driving force, a lighter diaphragm is more likely to generate a larger acceleration. As a result, it can quickly respond to changes in audio signals, improving the transient response performance of the speaker, and making the details of the sound more abundant. Especially in the high-frequency range, it can restore the sound more clearly.

 

Good Rigidity: Aluminum has high strength and rigidity, which can effectively resist the deformation of the diaphragm during the vibration process. This helps to maintain the shape stability of the diaphragm, reduce the distortion caused by the deformation of the diaphragm, and ensure the accuracy and purity of the sound. At the same time, an aluminum cone with good rigidity can withstand greater power and is less likely to crack or be damaged when driven at high volume or high frequency, improving the reliability and durability of the speaker.

 

Excellent Heat Dissipation Performance: Aluminum has good thermal conductivity and can quickly dissipate the heat generated by the voice coil. As mentioned earlier, the voice coil generates a large amount of heat during operation, and overheating can lead to an increase in the resistance of the voice coil, a decline in performance, or even damage. The good heat dissipation performance of the aluminum cone can reduce the operating temperature of the voice coil, maintain its normal operating state, extend the service life of the speaker, and also help to reduce the fluctuations in sound quality caused by temperature changes.

 

Wide Frequency Response: Due to the lightweight and good rigidity of the aluminum cone, its natural frequency is relatively high, and it can maintain good vibration characteristics within a wide frequency range. This enables aluminum cone speakers to perform excellently in the mid and high-frequency ranges, with bright and clear sound. At the same time, it can also provide a certain amount of power and texture in the low-frequency range, covering the entire audio range well and achieving high-quality sound playback across the full frequency band.

 

Corrosion Resistance: Aluminum easily forms a dense aluminum oxide protective film in the air, which has good corrosion resistance. This enables the aluminum cone to maintain stable performance under different environmental conditions, and it is not easily affected by factors such as humidity and oxidation, thus extending the service life of the speaker.
