The Ultimate Fusion of Full-Range Clarity and Deep Bass

Jimmy G. has often remarked:
"When subwoofers and full-range speakers are placed separately, numerous sound issues arise. The most immediate effect is a muddy, unrefined low frequency that lacks depth and definition."

In the modern entertainment industry, we have grown accustomed to speakers that seamlessly integrate full-range clarity with powerful subwoofers. Enter the PKOP® W4—a revolutionary super full-range speaker designed by Jimmy G. Though minimalist in appearance, its frequency response is anything but simple. While classified as a full-range speaker, the W4 extends effortlessly down to 20Hz, not just in frequency but in delivering a profound transfer of energy.

Step into a nightclub pulsing with music, and you’ll instantly feel the electrifying impact of deep, resonant bass paired with high-energy mids and highs—an intense contrast to the silence outside. However, if the audio system is improperly configured, prolonged exposure may lead to dizziness or even nausea. Why does this happen? The culprit is phase differential between misplaced subwoofers and full-range speakers. This discrepancy isn’t merely an artifact of electronic signal processing within a crossover—it persists even when independent subwoofers and full-range speakers are physically separated. Such phase misalignment introduces distortion, disrupting the musical balance and diminishing the listening experience.

For music to truly captivate, it requires a harmonious fusion of full-range clarity and deep, cohesive bass.

The W4 full-range speaker features an 18-inch low-frequency driver and a 1-inch compression driver. With its innovative design, it flawlessly reproduces a full-frequency signal, extending from a deep, resonant 20Hz to a crisp 20kHz. The low frequencies are particularly rich and dynamic, adding a sense of elasticity and depth to the music. Meanwhile, the meticulously engineered design enhances vocal clarity, delivering a commanding presence with exceptional penetration. Remarkably, no other speaker achieves such a powerful 20Hz–20kHz frequency range with just two drivers—making the W4 a groundbreaking innovation.

Beyond its exceptional tonal balance and power, the W4 effectively overcomes two major sources of phase distortion: one caused by electronic frequency division and the other by the physical separation of subwoofers and full-range speakers.

The W4 offers more than just outstanding sound—it also delivers practical advantages. Designed to be suspended, it saves valuable floor space, a significant benefit for bar and club owners seeking to maximize their venue layout.

Additionally, its hanging design ensures a more uniform sound field. In particular, the low frequencies benefit from the absence of acoustic absorption by furniture or crowds, significantly enhancing overall efficiency. As a result, achieving the same low-frequency impact requires only half the number of speakers compared to conventional setups. This not only optimizes performance but also instills confidence in investors—delivering superior results while reducing costs.
