        FAQ about the Peerless SLS-85S25CP04-04 Bass-midwoofer

        What is the primary application of the SLS-85S25CP04-04 Bass-midwoofer?

        The SLS-85S25CP04-04 is versatile, suitable for:

        • Compact speaker designs.
        • Multimedia speaker systems.
        • Portable audio projects.
        • Small bookshelf or satellite speakers.
        • 2-way or 3-way systems as a bass-midrange driver.

         

        How does the Peerless SLS-85S25CP04-04 Bass-midwoofer perform in terms of bass reproduction?

        The SLS-85S25CP04-04 provides solid bass performance for its size, with a lower frequency limit of 75 Hz. While it won't deliver deep sub-bass, it offers clean and punchy bass in small enclosures. For full-range systems, pairing it with a subwoofer is recommended for extended low-frequency output.

         

        What type of enclosure works best with the SLS-85S25CP04-04?

        This driver performs well in:

        • Sealed Enclosures: For tighter bass response.
        • Vented (Ported) Enclosures: For extended low-frequency output, tuned to its resonant frequency (Fs). The compact size allows it to be used in very small enclosures, making it ideal for portable or space-constrained designs.

        Nach der Bestellung gab es viele Infos zum Versand usw. Ich habe den 10 cm Subwoofer bestellt um meine alten Pioneer TS-X8 zu Reparieren, der Klang ist um einiges besser als davor. Reparatur gelungen. danke an Sound Imports
