Shahriar Posted October 25, 2006 Report Share Posted October 25, 2006 HiI want to build this Active 3-way cross-over circuit.But I do Not kow how to choose Power amplifiers. Here the problems:1- If I choose a 15W subwoofer and a 15W STK power Amplier (STK4121) for it then what kind of Midrange and tweeter will be needed?Does it mean I have to choose a 15w Midrange and a 15W tweeter?2- Should the gain of all PA be the same? i.e. if the Midranges are 8Ohm and Subwoofers are 4Ohm, how to choose the gain of PA?ThanX in advanceShahriar Quote Link to comment Share on other sites More sharing options...
