    Heresy?

    Here is the thing matching the output tap impedance with the loudspeaker impedance will maximize current transfer from the amplifier to the loudspeaker. That said impedance shifts up won't make a huge difference remember your speakers impedance shifts all over the place with frequency and to a much greater degree than the tap values offered on your output transformer. Multi tap transformers as a consumer compromise. One of the problems is that if you use let say the four ohm tap of a 4 - 8 - 16 ohm output transformer then most of the winding of your transformer secondary is not loaded it is simply flapping in the breeze. I have found that loading the full secondary almost always sounds better (this is why multi taps are a compromise). as I said the difference in current delivery under normal listening make very little to no difference so far as the amount of power delivered but loading the full secondary can in some cases make a very big difference to the sound quality. You can run on any tap you like give a try ad go with the tap that sounds best to you. If you cant tell then simply match the tap which is closet to the stated impedance of your loudspeakers but your ears should tell you which is best.



    Thanks

    I have a old fisher 2 channel on the back I have 16 ohm 8ohm and 4ohm what is the best for a pair of heresy it sounds the best on 16ohm but I don't want to mess up the speakers

    2 channel amplifier ?

    No


    Bridging means having both left and right outputs combine to increase the wattage output therefore making a more powerful single, mono amp. This would be selected on the amp.



    So you can't hook it up + on the left and -on the right like a car amp ?
