Test Bench: The SW26DBAC76-4 Shallow-Mounting Subwoofer from SB Acoustics

This Test Bench article analyzes the popular SW26DBAC76-4 10" low-profile subwoofer from SB Acoustics, specifically designed (and patented) for applications that require a subwoofer that will fit into very shallow-depth enclosures. The SW26DBAC76-4 has a unique and interesting feature set that starts with an extremely shallow 79.5mm (3.13") cast-aluminum frame. The outside rim of the inverted cone is attached to the outside perimeter of the spider, and moves with the cone assembly. The inside diameter of the spider that would normally be glued to the voice coil assembly is then connected to the motor structure. This is a clever design.
