QUANN LIUH CO., LTD., founded in 1996 with TENSONIC as a registered trademark, manufactured home stereo systems at the very early stage. With the advance of digital technology, we integrated digital controls and digital audio systems into our products earlier than other local makers. We expanded our production line to manufacture PA amplifier systems with modulized components such as CD ROM and USB Recorder/Player modules as optional parts. 

Except for our brand-name products - TenSonic, we manufacture on ODM and OEM orders. A team of engineers with analog electronics, digital electronics engineering and foreign language background is our greatest strength to work closely with major foreign suppliers such as TI, ROHM... to produce products to meet customer demanding requirements. Our R&D team is capable of designing products from ground zero.  All products are well made in Taiwan.
