Yo ! I've made myself a pair of speakers, that I salvaged from a big samsung TV that we threw off of the 2nd floor. The speakers were pretty much intact so I decided to fit them into home made cabinets and to build a dual rail power supply and an amp to drive them. The supply is a linear dual rail regulated power supply : Input 230VAC 50Hz Output : -18V, 0V, +18V - 1A/channel @36W The amp is based on a TDA7265 chip : 20W/channel @ THD 10% 16W/channel @ THD 1% The speakers are 8ohm 15W full range drivers. The cabinet has a bass reflex to compensate for the drop in gain from the amp and the lower efficiency of the drivers at low frequencies (20Hz-60Hz). The system produces a very clean, powerful and balanced sound and is working perfectly since December 2015. It's a keeper !
