CAVS HX218 Subwoofer

The CAVS HX218 subwoofer is a high-power subwoofer equipped with two 50cm bass drivers, designed to reproduce powerful, deep, and energetic bass.

With its Bass-reflex design and high power output, the HX218 is suitable for professional karaoke, stage performances, events, shows, and large-scale sound systems. It's a worthwhile option when you need to enhance the bass range and create a powerful, impactful sound foundation.

Introducing the CAVS HX218 Subwoofer

The CAVS HX218 subwoofer utilizes a Bass-reflex design, optimizing low-frequency reproduction and enhancing the subwoofer system's performance. Its frequency range is 32Hz – 150Hz (-10dB), while the response frequency is 40Hz – 150Hz (±3dB), allowing the HX218 to focus on bass frequencies and work well with the main speakers in the system.

In terms of performance, the HX218 boasts a power output of 1800W Continuous / 3600W Program / 7200W Peak, combined with a sensitivity of 99dB and an impedance of 8Ω. This configuration is geared towards systems requiring a large amount of bass and the ability to operate at high volume levels.

Technical parameters of the product to consider:

• Bass-reflex system: The CAVS HX218 utilizes a Bass-reflex design, perfectly suited to the characteristics of a subwoofer. This structure helps to increase energy reproduction efficiency in the low-frequency range, resulting in deeper and more powerful bass.
• 2 x 50cm bass speakers: The HX218 is equipped with two 50cm diameter woofers, creating a large soundstage and providing significant power to the bass range. This configuration is suitable for systems requiring strong bass and high sound pressure.
• Power output: 1800W / 3600W / 7200W The three power levels, Continuous / Program / Peak, reach 1800W, 3600W, and 7200W respectively. These specifications indicate that the HX218 is designed for high-performance systems. When pairing it with other equipment, it's necessary to choose an amplifier that can adequately match the power and impedance of the speakers.
• Frequency range 32Hz – 150Hz (-10dB): The ability to extend down to 32Hz allows the HX218 to handle low-frequency audio components well. The upper limit of 150Hz helps the speaker focus on reproducing bass rather than functioning as a full-range speaker.
• Frequency response 40Hz – 150Hz (±3dB): Within the 40Hz – 150Hz range, the reported response is within ±3dB. This is an important basis for establishing the crossover frequency between the HX218 and the main speaker, helping to distribute the sound frequencies more evenly.
• Sensitivity 99dB: A sensitivity of 99dB is an advantage for a high-powered subwoofer, indicating the speaker's ability to generate good sound pressure levels when given the right power. This parameter is particularly noteworthy when building stage or event sound systems.
• Impedance 8Ω: The HX218 has an impedance of 8Ω, making it easier to pair with many power amplifier models. When using multiple speakers, it is necessary to calculate the total impedance and the load capacity of the amplifier.
• Peak sound intensity: 138dB The 138dB peak level indicates that the HX218 is geared towards generating very high sound pressure. This specification is suitable for systems that require bass with significant coverage and energy.
• Dual subwoofer configuration: The use of two 50cm drivers gives the HX218 an advantage in bass output compared to single-driver subwoofers. This configuration is particularly suitable for large spaces or systems requiring significant low-frequency power.
• Designed for professional audio: Overall, the specifications of the HX218 indicate that the product is not focused on typical home karaoke needs but rather geared towards stage performances, events, shows, and professional sound systems.
• CAVS Professional Audio brand: The HX218 belongs to the CAVS Professional Audio product line, designed for audio configurations with high demands for performance and bass reproduction.
• Country of manufacture: According to the product information, the CAVS HX218 is manufactured in China.
