Enough with the kneecaps. I have heard all about phase cancellation with non-identical cabinets. I have stacked the speakers in different configurations and found that there is in fact some cancellation factor either running the 212 on its side or running the 2 110 cabs next to each other rather than vertically stacked. The Eden with the 3 cabs stacked vertically in the configuration I described driven at 4 ohms a side IS LOUDER than either side driven alone with the respective speaker(s), so I think that rules out potential frequency cancellation.
The 350 watt Hartke is louder through either a 4 ohm 212 cabinet OR the pair of CX110 cabs,( also a 4 ohm load) than the one side of the 400 watt Eden. I know 50 watts is not much power difference in terms of producing SPL or DB, but the apparent difference to my humble ears is quite noticeable.
It seems like I have gotten responses varyng from I don't know how to set the Eden to mixing apples and oranges with regard to speaker setups; a frustrating quandry for a simple question which was intended.
I shall simplify further:
The question is : identical speakers, 2 amp heads (set flat with identical gain and volume settings), and the less powerful amp is clearly louder. WHY?
