I have been messing around changing speakers for the last 2 weeks. I put a 8 ohm deltalite in my workingman 10. Since this amp has an extension jack and will handle 2-8 ohms speakers, would there be any advantage to getting all 100 watts to one 4 ohm speaker. (present config is 80 watts to an 8 ohm speaker) I am trying to get a better handle on multiple speakers pushing more air compared to more wattage to a single speaker. I would also like to hear from anyone on a link that might deal with the math to calculate these types of situations.
