The key to making a subwoofer small and stealthy is in the drivers. With traditional 12" and 15" drivers, the physical diameter and depth of the frame limits the options for how small the enclosure can be. Luckily, we live in an age where there is a large selection of small, high-performance subwoofer drivers.

Tang Band has been leading the charge in this fi eld by creating a number of high-performance small subwoofers based on impressive neodymium motors. The W6-1139SG was one of their fi rst such drivers, and has been a DIY favorite since it was released. With a great combination of a small diameter, shallow mounting depth, high power handling, and long excursion; it provided me the flexibility to create an unobtrusive and powerful subwoofer.
