    Speaker Cabinet Design and Construction

    Cabinets control the movement of air and vibrations. Key designs include:

    • Sealed (acoustic suspension): tight bass but less efficient.
    • Ported (bass reflex): uses tuned vents for extended low end.

    • Transmission line and horn-loaded: advanced designs offering higher efficiency.
      Construction materials (wood composites, plastics, metals) influence resonance, coloration, and durability.

    Most speaker cabinets will house multiple drivers, each handling different parts of the frequency spectrum. A 3-way speaker means there are three separate drivers in the cabinet (typically a woofer, midrange, and tweeter). A 2-way speaker contains two drivers (usually a woofer and tweeter). The number of drivers corresponds directly to the speaker’s ability to divide and reproduce the frequency spectrum more accurately.
