        • Ferrite magnet, steel basket, paper cone, and NBR rubber surround
        • 20 W AES, 40 W continuous, and 80 W peak power handling
        • 89.44 dB sensitivity with compact sealed enclosure options

         

        Product details REDCATT 41FR

        REDCATT 41FR 4.0" Full-range Woofer 8 Ohm

         

        The REDCATT 41FR is built for projects where a small-format full-range woofer is required without giving up usable high-frequency extension. Its 8 ohm voice coil, ferrite motor, and 89.44 dB sensitivity make it a practical choice for compact loudspeaker designs where efficiency, size, and cost need to stay well balanced.

         

        A lightweight paper cone with NBR rubber surround gives the 41FR a controlled moving system, while the optimized cone shape improves piston strength and helps reduce harmonic distortion artifacts. The driver uses a 25.4 mm CCAW voice coil on a Kapton former, supported by a Nomex spider and a steel basket for dependable mechanical construction.

         

        With 20 W AES power handling, 40 W continuous power, and 80 W peak power handling, this driver suits array applications, small two-way monitors, PA column midrange use, and compact speakers. In some designs, its extended HF response allows it to be used without a separate high-frequency unit.

         

        The 41FR is especially suited to very compact sealed enclosures and near-field desktop applications. Practical sealed volumes include 0.10 liters for ultra-compact panel-mounted systems, 0.25 liters for compact desktop enclosures, and 0.55 liters for small sealed designs where the driver can work as a standalone near-field solution. For DIY builders comparing compact woofers, the 41FR offers a useful combination of small size, extended response, and straightforward enclosure options.
