Members slej Posted October 21, 2006 Members Share Posted October 21, 2006 Can a 16 ohm resistor be paralleled with a 16 ohm speaker to result in an 8 ohm load "seen" by the amp? Will there be any harmful effects? What other values need to be known about the resistor?IS this a valid manipulation? Link to comment Share on other sites More sharing options...

Members tommythelurker Posted October 21, 2006 Members Share Posted October 21, 2006 Yes, in theory you can do that. You'd need a pretty honking big resistor as it needs to dissipate half of the power from the amp. In practice I don't think it would sound very good.

Members SteinbergerHack Posted October 21, 2006 Members Share Posted October 21, 2006 This is sort of how an attenuator works, although they use a series/parallel system. I've built some pass-through units similar to what you describe, and they DO work, but there are some issues..... Here's the rub: if you're running a 100W amp, you'll need that resistor to be at least 50W, and you'll need a pretty decent-sized heat sink on it. You see, a resistor absorbing 50W is, by definition, a 50W heater. If you can't find a resistor rated for 50W (heh, heh, heh), you'd need to series/parallel a group of resistors to get your total load handling up to 50W. This can be done, but you're probably better off just buying an attenuator, or buying the right impedance speaker or cabinet. Link to comment Share on other sites More sharing options...

I didn't believe 100% of what EVH Sound said. Link to comment Share on other sites More sharing options...
