Dear Talkbass, Is there any tonal difference between a 4 or 8 ohm cabinet if you had enough power to play both at the same volume? I understand that a 4 ohm would be louder but i've seen people mentioning that they've percieved it as 'punchier' than a 8 ohm cabinet, and the 8ohm is percieved to be 'fuller'. But how would that make a difference? I've spotted a lot of mixed responses on sites but is there any science behind it? I had a discussion with a shopowner, and he said that if you have the power, an 8 ohm is always better. It would sound fuller and you have the potential to upgrade it with a second cab. I don't think i'd ever get a second cabinet though..
