Thanks Saint - That’s the same motivation I had for wanting to put mine up in the first place - just a little bit closer to the ear, and have decided (following the comment from Jeff) not to at this time. I’m happy to hear that you have not heard a discernible difference getting yours off the stage. I also thought I might wait until another cabinet is in my budget and then add an SLT to the configuration to get something a little bit more at ear level. My other (budget) challenge is that I am using a Shuttle 9.0 and Jeff relayed that it does not want to operate at the lower ohms that the third cabinet would provide (I think this makes it a 2.67 ohms system). Our band travels and there is no room for additional milk crates/similar solution so I looked into a lot of amplifier stands, and did not find any that were very well-suited for the dimensions of my 12-3 cabs.You know, the coupling thing has always been a bit of a mystery to me. I certainly have had issues in the past with big boomy stages when I had amps that sat directly on the floor, and with my two 12-3's I keep them raised up, mostly for the sake of having them closer to to my head, using a pair of large black milk crates. I haven't noticed that they lack anything as a result, but I do hear them better.
When I inevitably get around to buying a third 12-3 I will get rid of the milk crates, and I suppose that will tell me something.
