Edifier T5 Editier T5 is an active subwoofer that allows you to expand your current 2.0 set by a powerful dose of low tones. Some of our sets have a special output marked "sub out". That's where we hook up Edifier T5 with RCA-mini jack. Subwoofer requires connection to the power source. Control is done by electronics built into the speakers. The port bass reflex is placed on the right side of the housing. Care should be taken to ensure that no furniture is covered Characteristics 70W RMS 8 inch woofer Transmission band from 38HZ MDF housing 21mm thick Phase correction RCA input and output Automatic "stand-by" function Universal power supply
