Yes, the Stiletto 4x12 is great, out of all the Mesa cabs I have tried, the Stiletto 4x12 is the best. It seems to maintain constant tone no matter where you stand and is tight, punchy and balanced.
I just bought a Stiletto 2x12 as I just don't want to move a 4x12 and the 2x12 seems to be the next best thing.
I am the oposite though in regards to having it on the floor. So far, I am just not happy with it on the floor and find that raising it 500mm or a bit more makes all the difference for me. I really hate the muffled muddy bass heavy tone with the cab on the floor, especsially if you have to stand close to it with it behind. At home, sticking a block under the front, angling it up and then standing in front is not so bad.
