        • Includes sealing gasket, mounting screws, and griff nuts for practical installation.

         

        Product details RS Speakers W 174.38 Fibonacci 8

        RS Speakers W 174.38 Fibonacci 8Ω 6.5" Woofer

         

        At the heart of the W 174.38 Fibonacci 8Ω is its unique para-elliptical paper pulp cone, precisely shaped and laser-etched to follow the Fibonacci sequence. This innovative design, inspired by the mathematical golden ratio, significantly reduces unwanted resonance modes in the cone, resulting in a smooth and balanced frequency response. The cone is further treated with an acrylic coating on the front and a damping layer on the back, creating a sandwich structure that expertly balances rigidity and internal damping. Such fine engineering ensures that the woofer delivers pure, uncolored sound with exceptional clarity.

         

        The mechanical design of this woofer is equally impressive. A rubber surround featuring Double Asymmetric Rolls technology and a meticulously crafted Conex spider with progressive waves provide both symmetrical excursion and excellent control at high output levels. The 1.5-inch voice coil is wound on a fiberglass former, maintaining mechanical stability and performance even during demanding, high-temperature operation. These features guarantee the woofer’s durability and reliability, making it suitable for intensive use in speakers and high-performance woofer applications.

         

        The RS Speakers W 174.38 Fibonacci 8Ω is designed with a robust ferrite magnet circuit, which includes an integrated aluminum demodulating ring to reduce coil inductance and minimize harmonic distortion. Strategic ventilation holes in both the magnet and voice coil further reduce power compression and turbulence, while the free compression basket with thin spokes eliminates rear reflections that can degrade sonic performance. These thoughtful details contribute to a highly efficient and responsive driver, ideal for use in both vented and sealed enclosures.

         

        With its combination of advanced engineering and premium materials, the RS Speakers W 174.38 Fibonacci 8Ω is an excellent choice for audiophile-grade DIY speaker kit projects, professional loudspeaker systems, and high-end home audio installations. Its precise manufacturing and focus on acoustic purity make it a standout component for anyone seeking to elevate their listening experience with top-tier transducer technology.
