The LS450AS<\/strong> is the amplified version of the LS450P<\/strong>, maintaining Lombardi\u2019s design philosophy: delivering real performance, high efficiency and superior sound quality<\/strong> compared to traditional reflex systems.<\/p>\n

Unlike the LS450AHS<\/strong>, the LS450AS is a simpler and more direct system, equipped with a single amplifier dedicated to the subwoofer, designed for applications where ease of use and fast setup<\/strong> are essential.<\/p>\n

\n
Horn-loaded technology and real performance<\/h5>\n

The horn-loaded design<\/strong> allows the LS450AS to achieve:<\/p>\n

    \n
  • high efficiency<\/li>\n
  • strong sound pressure<\/li>\n
  • excellent low-frequency control<\/li>\n
  • fast and precise response<\/li>\n<\/ul>\n

    Despite the 8″ woofer<\/strong>, the system delivers performance comparable to larger subwoofers.<\/p>\n

    The system maintains a linear frequency response across the full range<\/strong>, making it extremely versatile for any musical genre and suitable for both indoor and outdoor applications.<\/p>\n

    \n
    Integrated amplification<\/h5>\n

    The LS450AS is equipped with an internal amplifier delivering:<\/p>\n

    \u2022 450 W RMS at 8 ohms<\/strong><\/p>\n

    The amplification is designed to provide:<\/p>\n

      \n
    • high dynamic response<\/li>\n
    • reliability<\/li>\n
    • real control over the loudspeaker<\/li>\n<\/ul>\n

      The system is optimized to perfectly match the transducer, ensuring a consistent and controlled performance.<\/p>\n

      \n
      Flexible system integration<\/h5>\n

      The LS450AS<\/strong> can be used as the foundation of compact audio systems and is designed to operate in different configurations:<\/p>\n

      \u2022 pairing with active top speakers<\/strong>
      \u2022 use within systems with passive loudspeakers (without integrated amplification)<\/strong><\/p>\n

      This flexibility makes it highly versatile across different system setups.<\/p>\n

      \n
      System expansion capability<\/h5>\n

      The LS450AS allows connection of an additional passive subwoofer LS450P<\/strong>, lowering the system impedance and increasing overall low-frequency performance.<\/p>\n

      This configuration allows:<\/p>\n

        \n
      • increased sound pressure<\/li>\n
      • extended coverage<\/li>\n
      • consistent tonal balance<\/li>\n<\/ul>\n

        making the system suitable for larger applications.<\/p>\n

        \n
        Precision, speed and 8″ design<\/h5>\n

        The 8″ woofer<\/strong> allows:<\/p>\n

          \n
        • faster response<\/li>\n
        • higher precision<\/li>\n
        • improved note definition<\/li>\n
        • tighter low-frequency control<\/li>\n<\/ul>\n

          The result is a fast, clear and musical bass response<\/strong>, while maintaining the warm Lombardi sound character.<\/p>\n

          \n
          Lightweight cabinet and Lombardi construction<\/h5>\n

          The cabinet is built using three types of wood:<\/p>\n

          \u2022 poplar plywood<\/strong> (lightweight and warm sound)
          \u2022 birch plywood<\/strong> (structural strength)
          \u2022 spruce front panel<\/strong> (optimized acoustic response)<\/p>\n

          This combination results in a cabinet that is lightweight yet extremely robust<\/strong>.<\/p>\n

          \n
          Compact size and portability<\/h5>\n

          The LS450AS<\/strong> is designed to be:<\/p>\n

            \n
          • easy to transport<\/li>\n
          • lightweight<\/li>\n
          • compact<\/li>\n<\/ul>\n

            It can be used even in simple logistical conditions, making it ideal for:<\/p>\n

              \n
            • DJ sets<\/li>\n
            • small events<\/li>\n
            • mobile audio services<\/li>\n<\/ul>\n
              \n
              Integration with Lombardi systems<\/h5>\n

              The LS450AS integrates perfectly with:<\/p>\n

              \u2022 LVR400HP<\/strong><\/p>\n

              and is ideal for building compact and efficient sub-satellite systems.<\/p>\n

              \n
              Lombardi philosophy<\/h5>\n

              The LS450AS follows Lombardi\u2019s philosophy:<\/p>\n

              \ud83d\udc49 real performance over commercial compromise<\/strong><\/p>\n

              delivering:<\/p>\n

                \n
