        Product details RS Speakers W 220.50 Fibonacci 8

        RS Speakers W 220.50 Fibonacci 8Ω 8” Woofer

         

        The W 220.50 Fibonacci is a true flagship among woofers, featuring an innovative paper cone meticulously crafted with a para-elliptical shape and laser-etched Fibonacci sequence pattern. This unique design not only enhances cone rigidity but also minimizes unwanted resonance, resulting in exceptionally pure and natural sound. The “sandwich” cone structure is treated with both an acrylic coating on the front and a damping layer on the back, ensuring a perfect balance between stiffness and internal damping for detailed and dynamic audio reproduction.

         

        Special attention has been paid to the suspension system. The rubber surround utilizes Double Asymmetric Rolls technology, providing symmetrical excursion and superior control over cone movement. The progressive Conex spider further optimizes linearity and minimizes mechanical offsets, allowing for clean bass response even at high output levels. The 2-inch voice coil, wound on a fiberglass former, guarantees mechanical stability and reliability under intense operating conditions, making this woofer ideal for high-fidelity speakers and advanced DIY projects.

         

        The magnetic circuit employs a robust ferrite magnet with a ventilated design, reducing power compression and ensuring consistent performance over long listening sessions. An aluminum demodulating ring has been integrated to lower the overall inductance and reduce harmonic distortion, enhancing clarity across the frequency range. The free compression basket design, featuring thin spokes, eliminates rear reflections and further improves the accuracy of the soundstage.

         

        With a rated AES power handling of 200 W and a sensitivity of 91.3 dB at 1W/1m, the RS Speakers W 220.50 Fibonacci is perfectly suited for both high-end home audio and professional loudspeaker systems. Its precise engineering and premium components also make it an excellent choice for DIY speaker kits and custom installations. All necessary mounting hardware is included, ensuring straightforward integration into your next project. Experience the pinnacle of Italian loudspeaker innovation with this remarkable bass-mid woofer.
