impedence (1 Viewer)

[David Giesbrecht]

I was wondering if you could change the impedence load of a speaker by simply putting a resistor in the line between it and the amp.

The simple answer is yes you could. But don't. Unless you're using the resistor to increase the load and attenuate the speaker. Because if you put it in parallel with the speaker (to decrease the load) the current will divide and you won't really see much if any more power from your amp and you'll be driving it harder (and making lots of heat from the resistor). If you use one to attenuate a speaker make sure it has a high enough wattage rating or you'll fry it.

Thanks this really helps alot, I am actually trying to make a 2 ohm speaker an 8 ohm.
