        RS Speakers MW 174.38 Fibonacci 6.5” Mid woofer 8Ω

         

        The MW 174.38 Fibonacci stands out with its innovative diaphragm, crafted using a custom para-elliptical profile and laser-etched surface inspired by the Fibonacci sequence. This architectural approach, paired with a dual-surface damping treatment, achieves a "sandwich" structure that expertly balances rigidity and damping. The result is a reduction of unwanted resonance modes and an incredibly natural, detailed sound signature that excels in both bass and midrange frequencies.

         

        Designed for demanding audio applications, this woofer incorporates a 1.5-inch voice coil on a fiberglass former, ensuring stability even at elevated temperatures and high dynamic loads. The advanced magnetic circuit, featuring a ferrite magnet with an aluminum demodulating ring, guarantees a highly symmetrical magnetic field and reduced inductance for lower harmonic distortion. These enhancements make the MW 174.38 an outstanding choice for woofers in audiophile-grade systems and custom installations.

         

        Installation flexibility is another key asset, with a free compression basket that uses thin spokes to minimize rear reflections and maximize airflow. The robust die-cast aluminum frame, progressive Conex spider, and NBR butyl rubber surround with a dual-wave profile all contribute to precision cone movement and longevity. With a sensitivity of 90.2 dB and a rated AES power of 130 W, this driver is ready to excel in both 2-way and 3-way loudspeaker configurations.

         

        Whether you are designing high-performance home audio systems or custom DIY speaker kits, the RS Speakers MW 174.38 Fibonacci ensures uncompromising sound quality and reliability. Its extended frequency response and refined phase plug facilitate seamless integration with tweeters, while the supplied mounting hardware and gasket make assembly straightforward. For those seeking top-tier components for their next audio project, this driver represents the fusion of Italian design and acoustic innovation.
