i thought I saw both 4 and 8 ohm speakers on the internet. It was an online stereo/speaker warehouse. I can't find it now, however, so I am probably wrong in that statement. I can only find 2 and 4 ohm variants.
Let me ask this: Couldn't I just add a 4 ohm resistor before the sub to simulate a total resistance of 8 ohms?
If I could find a direct replacement 8 ohm sub would I even notice a difference in the sound?
Thanks again for your help!
