[sdiy] SOT: speakers & theory...

[Nils Pipenbrinck]

Well, once again a guitar amp related question. Tried to get some help 
elsewhere, but I'd like to have a technical answer instead of a flamewar :)


Say you have two 8 ohm speakers connected to an output transformer.

How does the frequency response and efficiency factor changes if you:

 * connect them in series, and feed them from the 16 ohm transformer tap.
 * connect theem in parallel and feed them from the 4 ohm transformer tap.

I've noticed a *huge* difference in tone and perceived volume when I 
change the configuration. But to be honest I don't understand why it 
makes any difference.
