KTreasure WF118 Subwoofer

The KTreasure WF118 subwoofer is an 18-inch subwoofer designed for professional karaoke systems, stages, auditoriums, and event sound. Possessing the ability to reproduce deep, powerful, and energetic bass, the WF118 enhances the bass effect, providing a more vibrant music and karaoke experience.

Introducing the KTreasure WF118 Subwoofer

The KTreasure WF118 single subwoofer is a professional subwoofer model using a single 18-inch subwoofer driver. With a frequency range of 33Hz – 250Hz (±3dB), the WF118 delivers deep, solid, and energetic bass, making the overall sound system fuller and more vibrant.

The KTreasure WF118 boasts a rated power of 1200W and a peak power of 1800W, combined with a sensitivity of 99dB and a maximum SPL of 134dB @ 1m. These specifications indicate that the speaker is geared towards systems requiring high sound performance, particularly suitable for spaces with high demands on bass pressure and energy.

Technical parameters of the product to consider:

• Configuration: 1 × 18-inch Subwoofer: The WF118 uses an 18-inch subwoofer, ideal for reproducing deep and powerful bass. The large size of the driver allows the product to effectively handle systems requiring strong bass, especially professional karaoke, stage performances, and events.
• Frequency response range: 33Hz – 250Hz (±3dB) The frequency range down to 33Hz allows the WF118 to reproduce low bass frequencies distinctly, while the upper limit of 250Hz helps the speaker focus on handling the bass range. When combined with full-range speakers and a suitable crossover setup, the frequency range between the subwoofer and the main speakers will be more evenly distributed.
• Sensitivity: 99dB (SPL 1W/1M) With a sensitivity of 99dB, the WF118 is capable of producing high volume levels with relatively efficient input power. This is an advantage when used in systems requiring high sound pressure while still optimizing amplifier performance.
• Nominal impedance: 4Ω: A 4Ω impedance requires the power amplifier to be able to handle the corresponding load. When a suitable main amplifier is selected, the WF118 can effectively utilize its power and maintain stability during operation.
• Power: 1200W Rated / 1800W Peak The 1200W rated power indicates that the WF118 is geared towards systems with high bass power requirements. The 1800W peak provides additional headroom for music with strong bass or programs requiring high volume.
• Max SPL: 134dB @ 1m With a maximum sound pressure level of 134dB, the WF118 is capable of generating significant bass pressure, making it suitable for commercial karaoke rooms, stages, auditoriums, and event sound systems. When operating at high volume levels, selecting the right amplifier and setting the appropriate limiter remains crucial to protect the speaker.
• Connectors: 2 × Speakon NL4 (+1/-1) Two Speakon NL4 connectors provide convenient and secure connection to the power amplifier. This configuration also supports flexible wiring in professional audio systems.
• Box material: Thick, high-durability plywood. The speaker cabinet uses thick plywood, which increases structural rigidity and reduces vibrations when the speaker driver operates at high power levels. This is also a suitable choice for systems that are frequently transported or used in professional environments.
• Finish: German Libao Black Hard Water-Based Paint The black finish protects the speaker cabinet surface while creating a professional look. The hard coating is also suitable for frequent use in portable sound systems.
• Dimensions: 700 × 690 × 561mm: Larger than typical 15-inch subwoofers, the WF118 is suitable for configurations requiring high bass output. Users should position the WF118 in a stable location with sufficient space for operation and convenient transportation and installation.
• Packaged weight: 51,9 kg Weighing nearly 52kg, the WF118 boasts a robust construction and is geared towards professional audio systems. When installing or moving it, at least two people are recommended for safety and convenience.
