TangBand

In 1996 Tang Band Limited was founded in Taipei, Taiwan. The main purpose of Tang Band is to produce innovative, top quality loudspeaker drivers. To achieve this goal engineers were hired with extensive experience in acoustic design, material science and quality assurance. Tang Band's efforts resulted in very popular full range drivers, often used in small speaker cabinets, like e.g. Lancetta, CT 209

The cabinet volume calculations are executed considering an external resistance of 0.3 Ohm. We are using, if no other data is known or available, the information supplied by the manufacturer.

Please note: the frequency response doesn't say much about the cut-off frequency inside the cabinet! Therefore, we mostly give you 2 examples with dimensioning considerations and an indication, how low the loudspeaker will reproduce.
