CAVS ZK218 Subwoofer

The CAVS ZK218 subwoofer is a high-power subwoofer equipped with two 50cm bass drivers to deliver a powerful, deep, and energetic bass sound.

This product is suitable for professional karaoke systems, stages, events, and sound configurations requiring high-level bass reproduction. The plywood cabinet, finished with high-quality polyurethane paint, gives the ZK218 a robust structure, suitable for frequent use.

Introducing the CAVS ZK218 Subwoofer

The CAVS ZK218 subwoofer is equipped with two 50cm diameter woofers, using Ferrite magnets, combining a 4-inch voice coil and an 8.7-inch Ferrite magnet.

The ZK218 utilizes a Bass-reflex design, optimally focused on bass reproduction. The speaker has a frequency response of 31Hz – 200Hz (-10dB), while the dynamic range is 35Hz – 200Hz (±3dB). This allows the speaker to handle the bass frequencies independently, supporting the main speaker in focusing better on the mid and high frequencies.

Technical parameters of the product to consider:

• Bass-reflex system: The CAVS ZK218 utilizes a Bass-reflex design, well-suited to the characteristics of high-power subwoofers. This structure helps the speaker efficiently harness energy in the low-frequency range, creating a strong bass foundation suitable for large-scale sound systems.
• 2 x 50cm woofers: The ZK218 is equipped with two 50cm diameter speakers using Ferrite magnets. The dual-bass configuration increases the sound dispersion area, allowing the speaker to produce a greater amount of bass energy compared to single-bass subwoofers.
• 4-inch voice coil: Each speaker driver is equipped with a 4-inch voice coil, supporting high power handling capabilities and aligning with the ZK218's aggressive design philosophy.
• 8.7-inch Ferrite Magnet: The speaker driver uses an 8.7-inch ferrite magnet, contributing to a suitable magnetic system for operating the driver at high power levels.
• Power output: 1600W / 3200W / 6400W The ZK218 has three power levels: Continuous 1600W, Program 3200W, and Peak 6400W. This is a high-power configuration, aimed at systems requiring strong bass and the ability to operate at high volume levels. When pairing, it is necessary to choose a power amplifier that matches the 4Ω impedance and the actual power of the speakers.
• Frequency range 31Hz – 200Hz (-10dB): The ability to extend down to 31Hz allows the ZK218 to reproduce more sound components in the low-frequency range. This response range is well-suited to its role as a subwoofer, helping to add deep bass to the system.
• Frequency response 35Hz – 200Hz (±3dB): Within the 35Hz – 200Hz range, the speaker's response is within the ±3dB limit as per the specifications. This is an important parameter when setting up the crossover between the ZK218 and the main speakers.
• Sensitivity 96dB: A sensitivity level of 96dB indicates the speaker's ability to generate good sound pressure with appropriate input power. When combined with high power, the ZK218 has an advantage in systems requiring high sound levels.
• Impedance 4Ω: The ZK218 has an impedance of 4Ω, so the amplifier needs to be able to operate stably at this load level. This is a particularly important parameter to consider when matching power amplifiers, especially when using multiple speakers.
• Peak sound intensity: 138dB The 138dB peak level indicates that the ZK218 is designed for generating very high sound pressure. This specification is suitable for systems requiring bass with significant dispersion and energy.
• Plywood speaker cabinet: The speaker cabinet is made from plywood, providing a sturdy structure suitable for the vibration resistance required of a high-powered subwoofer. This material is also suitable for systems that require frequent transportation and installation.
• High-quality polyurethane resin paint: The polyurethane paint finish enhances the protection of the speaker cabinet surface while creating a professional appearance suitable for professional audio environments.
• Size: According to the information you provided, the dimensions (H × W × D) are 590 × 1800 × 720mm. However, a width of 11800mm is unusual for a speaker weighing 90kg; it's highly likely this specification was entered incorrectly. When posting on the website, you should double-check the actual dimensions to avoid inaccurate product information.
• Weight: 90 kg/piece Weighing in at 90kg, the ZK218 belongs to the group of subwoofers with a large and robust construction. This weight also indicates that the product is more suitable for fixed installation systems or requires a support team for transportation and setup.
• Black color: Black exudes a professional style and is easy to match with stage speakers, line array speakers, and other audio equipment in the same system.
• Made in China: According to the product information, the CAVS ZK218 is manufactured in China.
• 1 year warranty: The product comes with a 1-year warranty, giving users added peace of mind when investing in and using the speakers in professional sound systems.
