There was a thread here on decoupling speakers from the floor by setting them on plinths with an inert material between the speakers and plinths. I tried this and am amazed at the improvement in image and soundstage. My speakers are only 36 inches tall so I'm thinking some of the improvement comes from the extra two inches in height.
As the hawks are a fairly short speaker, this may work for you also. Before building the plinths and setting spikes in them I tried setting the speakers on thick phone books. Try this experiment and see if the results are positive. I'll bet they are.
