KTreasure WF218 Subwoofer

The KTreasure WF218 is a dual subwoofer designed for professional sound systems, stages, and large-scale events. It delivers powerful, deep, and energetic bass, significantly enhancing the overall impact of the sound system.

Introducing the KTreasure WF218 Subwoofer

The KTreasure WF218 subwoofer is a dual subwoofer model with a frequency response of 30Hz – 200Hz (±3dB), reproducing deep and powerful bass while effectively handling the low-frequency range of the system. When combined with full-range speakers or line array speakers, it helps create an overall sound with a solid, full bass foundation and a more powerful feel.

In terms of performance, the KTreasure WF218 boasts a rated power of 2400W, a peak power of 3600W, a sensitivity of 99dB, and a maximum SPL of 132dB @ 1m. This configuration allows the speaker to effectively handle events requiring high volume levels and powerful bass, especially stage performances, DJ sets, events, and professional sound rental systems.

Technical parameters of the product to consider:

• Configuration: 2 x 18-inch subwoofer speakers The KTreasure WF218 uses two 18-inch subwoofers in a single enclosure. This dual-sub configuration significantly increases airflow, creating a powerful bass foundation and is suitable for sound systems requiring high bass pressure.
• Frequency response range: 30Hz – 200Hz (±3dB) The frequency range starting at 30Hz allows the WF218 to reproduce very low bass frequencies, providing a deep and resonant bass feel. The 200Hz limit helps the speaker focus primarily on the bass range, making it convenient for pairing with full-range or line array speakers via a crossover system.
• Sensitivity: 99dB (SPL 1W/1M) With a sensitivity of 99dB, the WF218 boasts relatively high acoustic performance, capable of generating significant sound pressure levels without requiring excessive input power. This is a beneficial feature for use in large-scale stage and event systems.
• Nominal impedance: 4Ω: The WF218 has an impedance of 4Ω, so a power amplifier capable of stable operation at this load level needs to be selected. With a suitable power system, the speakers can effectively utilize the high power required by the dual subwoofer configuration.
• Power: 2400W Rated / 3600W Peak The 2400W rated power indicates that the WF218 belongs to the high-power subwoofer category, aimed at professional systems. The 3600W peak power provides extra reserve for music or programs with strong transient bass, helping the system maintain its power even at high levels.
• Max SPL: 132dB @ 1m With a maximum sound pressure level of 132dB, the WF218 produces a significant amount of bass, making it suitable for stages, auditoriums, events, and outdoor sound systems. When operating at high power levels, setting the limiter and selecting a suitable amplifier remains crucial.
• Connectors: 2 × Speakon NL4 (+1/-1) Two Speakon NL4 connectors provide a secure connection suitable for professional audio systems. This configuration makes connecting the WF218 to a power amplifier more convenient in both fixed and mobile systems.
• Speaker cabinet material: Thick, highly durable plywood. The speaker cabinet uses thick plywood, which increases structural rigidity while minimizing unwanted vibrations when the two 18-inch drivers operate at high power. This is also a suitable choice for systems that are frequently transported.
• Finish: German Libao Black Hard Water-Based Paint The hard black paint finish protects the cabinet surface and creates a professional look. This finish is also well-suited to the specific needs of stage, event, and sound rental systems.
• Dimensions: 1160 × 920 × 580mm: The WF218 is quite large due to its dual 18-inch subwoofer configuration. Proper space is necessary for installation to ensure optimal bass performance, while also facilitating transportation and setup.
• Packaged weight: 93 kg Weighing in at 93kg, the WF218 is a professional subwoofer with a large and sturdy construction. Given this weight, transportation and installation should be carried out by multiple people or with the use of support equipment to ensure safety.
