Vonyx WK20 - 8-inch (20cm) 250W RMS Hi-Fi Woofer with Woven Cone

Vonyx WK20 - 8-inch (20cm) 250W RMS Hi-Fi Woofer with Woven Cone

The Vonyx WK20 is a high-performance woofer designed for Hi-Fi enthusiasts seeking accurate, powerful, and reliable low-frequency reproduction. Part of Vonyx's acclaimed WK series, this 8-inch (20 cm) component is built with premium materials to ensure exceptional durability and superior sound performance. Its design makes it the perfect choice for replacing a damaged woofer in an existing speaker system or for starting a new DIY audio project.

The core of its performance lies in its distinctive yellow cone, crafted from a reinforced woven material. This construction not only gives it a professional appearance but also provides exceptional rigidity with minimal weight. The result is a fast and accurate transient response, capable of reproducing the deepest bass and the fastest transients without distortion or warping. Complementing the cone, a flexible yet durable rubber surround allows for linear and controlled excursion, enhancing sound quality and ensuring a long lifespan.

Main Features

• Robust Power: With a handling capacity of 250W RMS and peaks of up to 500W, the WK20 delivers powerful and sustained performance effortlessly.
• Woven Fiber Cone: The rigid and lightweight cone ensures crisp and detailed bass reproduction, minimizing unwanted resonance.
• High Strength Voice Coil: Equipped with a 1.5-inch, 4-layer voice coil, ventilated for efficient heat dissipation, ensuring reliability even during extended listening sessions at high volume.
• Powerful Magnetic Motor: A large 29-ounce ferrite magnet provides the magnetic field needed for precise cone control and high efficiency.
• Durable Rubber Suspension: The high-quality rubber rim or suspension offers excellent flexibility and fatigue resistance, allowing for smooth and controlled cone movement.
• Standard Impedance: Its 8 ohm impedance ensures wide compatibility with most home audio amplifiers and receivers and professional sound systems.

Benefits and Advantages

Integrating the Vonyx WK20 into your audio system translates directly into a tangible improvement in sound quality. You'll enjoy deeper, more defined, and punchier bass that adds a new dimension to your music and movies. Its robust construction not only ensures reliable long-term performance but also protects your investment, withstanding power spikes without compromising the speaker's integrity. The combination of its woven cone and powerful magnetic motor results in superior efficiency, meaning you'll get a higher sound pressure level with less amplification power.

Use Cases

The versatility of the Vonyx WK20 makes it ideal for a variety of applications:

• Speaker Restoration and Improvement: It is the perfect component to replace old, damaged or lower quality woofers in bookshelf or floorstanding speakers, giving them a new life and superior performance.
• DIY Audio Projects: For hobbyists and professionals building their own speaker systems, the WK20 is an excellent base for creating 2 or 3 way hi-fi systems or compact and powerful subwoofers.
• Customized Sound Systems: Can be used in audio setups for small venues, bars or home studios that require reliable, high-quality low-frequency reinforcement.

Frequently Asked Questions

What type of speaker enclosure is recommended for this woofer?

The Vonyx WK20 is versatile and can work well in both sealed enclosures, for more controlled and precise bass, and ported/bass-reflex enclosures for greater low-frequency extension. The choice will depend on the desired sound.

Is it suitable for use as a subwoofer in a car?

No. This woofer has an impedance of 8 ohms, which is standard for home and professional audio applications. Car audio systems typically use 4- or 2-ohm speakers. Using an 8-ohm speaker would significantly limit the power delivered by a car amplifier.

Can I use it to replace a 6 ohm or 4 ohm woofer?

Technically possible, but not recommended without adjusting the crossover (frequency filter). Changing the impedance will affect how the filter divides the frequencies between the speakers (woofer, tweeter, etc.), which can negatively alter the speaker's sound balance. Furthermore, the amplifier will deliver less power to an 8-ohm speaker than to a 4-ohm speaker.

What advantages does the woven material cone offer?

The woven material, often composed of fibers such as aramid or fiberglass, offers an excellent stiffness-to-weight ratio. This allows the cone to move like a perfect piston, reproducing bass frequencies with great accuracy and minimizing the distortion that can occur with cones made of softer materials.

Project description

This 8-inch (203 mm) woofer is rated at 250W RMS and 500W peak. Designed with an 8-ohm impedance, it features a reinforced woven cone and a rubber surround.
