Ok, Here i am again contemplating too many things as usual. I have decided i need more power from my WT-550. I currently have an 8 ohm Eden 410xlt. I have decided that a switch to at least a 4 ohm cab is needed. Option 1. Trade the 410xlt in on an Epifani 410ul therefore getting the 4 ohm load i want and basically halving the weight i have to lug. Option 2. Trade the 410xlt in on 2 4 ohm Epifani 210ul's therefore getting the 4 ohm load i want and having the option of running the head at 2 ohms and getting 750 watts into 410's. Just a question as well. How would the 410xlt at 8 ohms compare to a 210ul at 4 ohms???? I know the Eden is more efficient and is generally gonna move more air but is there gonna be a big volume difference???? Thanks.
