Tang Band's line of patented speaker modules are designed for modern audio applications such as sound bars, desktop multimedia speakers, flat panel tv speakers, and portable audio systems. Don't let Tang Band's diminutive driver modules fool you; each is built with a passive radiator that extends midbass frequency response, allowing these to mate to a subwoofer system quite easily.

The T1-1931S speaker module from Tang Band is built around a passive radiator assisted, polypropylene composite 31 mm inverted dome driver. This allows for a very full frequency response from a single, small driver. Advantages of this type of speaker design include the elimination of crossover components in the critical midrange, superb off-axis response due to the use of a small driver (without hot spots), and perfect time-alignment.
