Down4Sound Down4Sound D4S-AX5S | 5-Way Digital Powered Crossover

Description Warranty Information 1 Review Description The Down4Sound D4S AX5S 5 Way Digital Crossover is designed for car audio enthusiasts and professional installers who want precise system control without the complexity of software based DSP processors. Instead of relying on apps, laptops, or layered menus, the AX5S delivers direct digital crossover control through hands on, real time adjustment knobs. This approach allows you to tune your system instantly while listening, making it easier to dial in crossover points, balance output levels, and refine bass response without interrupting the listening experience. Complete System Frequency Control The AX5S provides dedicated subwoofer, front, and rear outputs , giving you full frequency management across your entire audio system. Each output section features independent level controls and adjustable filtering so every speaker receives only the frequencies it is designed to play. High pass, low pass, and band pass filters allow accurate crossover tuning for multi amplifier systems. A built in subsonic filter protects subwoofers from damaging ultra low frequencies, while bass boost and phase control help fine tune low end impact and integration. A wired remote bass level control is included, allowing convenient subwoofer adjustment directly from the driver’s seat. Designed for Clean Signal and Long Term Reliability The AX5S is built with sound quality and durability in mind. High quality Tiffany style RCA inputs ensure a secure, low noise connection, while gold plated terminals maintain strong signal transfer over time. Internal fuse protection and a compact, rugged chassis make the AX5S suitable for daily driven vehicles, competition builds, and professional installations. With a strong 9 volt RMS output and low total harmonic distortion, the AX5S delivers clean, consistent signal to your amplifiers. Ideal Use Cases The D4S AX5S is ideal for active car audio systems, multi amplifier setups, bass focused builds, and SQL systems that require precise crossover control without digital complexity.
