there are probably benefits from raising the tweeter as the 1.6 is relatively short. also if you have a wooden suspended floor as in an upstairs room, or any that isn't solid like a concrete floor, you might well benefit from placing the speakers on stone plinths or perhaps paving slabs. i'm having some 3 cm thick black zimbabwe granite plinths made for my 1.6s. i have wooden floors throughout my apartment, and i can feel them resonate (which i'm sure is colouring the sound). i'm going to use spikes under the plinths and at least temporarily, use spike cups under the four spikes. later i am thinking i might try stillpoints between the plinths and the 1.6s. i figure that 3cm thick granite is likely to have enough mass to damp the vibrations whilst also raise the tweeters to a more useful height.
