Ohmage? (1 Viewer)

Hey All,
Can I get away with mixing ohm ratings in my system. For example, if I have 8 ohm fronts and center can I use 4 ohm rears? I am trying to decide what to look at for the rears.
Thanks,
Casey H

Yes, you can get away with this just fine.
The one issue with 4 ohm speakers is that they can draw more current. But since the rear speakers get a lot-less signal than the fronts, this should not be a problem.
But if you want to be safe, remember that it's the low-frequency sounds that take the most power. You can tell your receiver to NOT send the low-frequency sounds to the rears by defining them as SMALL.
And then you will need to use a SPL meter to calibrate/level-adjust that mix of speakers.
Good Luck.
