Mismatched Speaker Impedance

DummannArt · 10th May 2008, 01:05 PM

I am new at audio and would appreciate some advice.

I am building a battery powered speaker. The amp will work with 4 and 8 ohm speakers.

Can I use a 4 ohm on one channel and an 8 ohm on the other?

Thanks,

Carl

For the same volume setting, the 4 ohm side will be taking 2 watts from the amp for each watt the 8 ohm side takes.

The 4 ohm will also be slightly, (3 dB) louder.

If that doesn't bother you, I see no reason you can't do it.
