        FAQ about the Peerless SDS-P830878 Passive Radiator

        What are some ideal applications for this passive radiator?

        The SDS-P830878 is perfect for:

        • Compact subwoofer systems.
        • Portable Bluetooth speakers.
        • Bookshelf speakers needing deeper bass in a small enclosure.
        • High-end custom DIY audio projects.

         

        How do I calculate the optimal tuning frequency for my system?

        To calculate the tuning frequency, consider:

        1. Active Driver Parameters: Check the Thiele/Small parameters of your active driver (Fs, Vas, Qts).
        2. Enclosure Volume: Determine the internal volume of your enclosure.
        3. Radiator Mass: Adjust the SDS-P830878’s mass to achieve a resonant frequency slightly below the active driver’s Fs for smoother low-frequency roll-off.

        Speaker design software (e.g., WinISD) is highly recommended for precise calculations.
