The QSB121 21 inches Passive Subwoofer Speaker from Quested is a powerful and high-performance audio component designed to deliver deep, resonant bass for music and home theater systems. This subwoofer boasts a large 21-inch cone driver, which provides an impressive amount of low-frequency output and superior bass response.
The cone is made of high-quality, long-fiber paper, which ensures rigidity and durability. The driver's voice coil is made of aluminum, which not only reduces the weight of the subwoofer but also provides excellent heat dissipation for consistent performance during long playback sessions.
The QSB121 features a front-firing port design, which provides efficient bass extension and a smooth frequency response. The subwoofer's enclosure is made of high-density MDF, which reduces resonance and vibration, ensuring accurate and clear bass reproduction.
The speaker's sensitivity is rated at 2.75 dB, and it can handle a maximum power of 500 watts. This makes it an excellent choice for applications that require high power handling and deep bass response, such as home theaters, nightclubs, and live music venues.
The QSB121 comes with gold-plated binding posts, which provide secure and reliable connections for speaker wires. The subwoofer also includes a detachable grille, which protects the speaker from dust and debris while allowing the beautiful design of the cone and voice coil to be visible.
Overall, the Quested QSB121 21 inches Passive Subwoofer Speaker is a high-performance audio component that delivers deep, powerful bass for music and home theater systems. Its large 21-inch driver, high-quality materials, and efficient port design make it a top choice for audio enthusiasts and professionals alike.
