Experience deep, thunderous bass with our high-performance 21-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.

1. High Magnetism: Neodymium magnet is a high-performance permanent magnetic material with strong magnetism. This enables the speaker to generate a powerful magnetic field, so that the voice coil is subjected to a greater force in the magnetic field, pushing the paper cone to vibrate and producing a louder sound.
2. Small Volume and Light Weight: When generating the same magnetic field strength, the volume and weight of the neodymium magnet are much smaller and lighter than those of the traditional ferrite magnet. This is beneficial for the miniaturization and lightweight design of the speaker, making it convenient for installation and use. At the same time, it also helps to reduce the overall weight of the speaker.
3. Good Stability: Neodymium magnet has good temperature stability and demagnetization resistance. Under different environmental temperatures, it can maintain relatively stable magnetism, thus ensuring the stable performance of the speaker and reducing the decline in sound quality caused by temperature changes.

1. Lightweight: Due to the low density of aluminum, the aluminum cone is very light in weight. A light paper cone can respond more sensitively to the changes in the audio signal and vibrate quickly, thus being able to restore the details and dynamic range of the sound more accurately. Especially in the mid-bass part, it can better show the strength and elasticity of the low frequency.
2. High Rigidity: The aluminum cone has high rigidity and can maintain a good shape during the vibration process, and is not easy to deform. This helps to reduce distortion, ensure the purity of the sound, and make the mid-bass clearer and more accurate.
3. Excellent Heat Dissipation Performance: Aluminum has good thermal conductivity, which can effectively dissipate the heat generated by the voice coil during the working process, avoiding the damage of the voice coil due to overheating and improving the reliability and service life of the speaker.
4. Timbre Characteristics: The aluminum cone material itself has certain timbre characteristics. It can bring a bright and clear texture to the sound, making the sound fuller and more layered in the mid-bass part. At the same time, it can also improve the high-frequency extension to a certain extent, making the sound performance in the entire audio range more balanced.
