Piece of cake, the Watt is about 60lbs, first disconnect the cable and pull it to the other side of the handle, the silver metal bar is actually a handle as wilsons watts were designed for portable recording monitors that acutally sat on the ground. pull it back slightly from behind (1/2") and then lift the back up with your fingers on lip of the midrange driver and lift it off, there are three spikes under the watt and metal slides on the puppy for it to rest on. this makes it easier to move the wilson speaker around.. another trick if you are going to mess with the spikes is to bring out your wilson plastic bags and lay the puppy down on them otherwise if you set either speaker on carpet the velcro will grab it and it will take 3 people to pull the speaker off and break the velco seal with a plastic knife. also there is a lip on the top of the puppy that you SHOULD NOT GRAB when moving the PUPPY's around as this can break, use the port and the lip around the drivers.
Since your have pulled the speaker check out the bottom with the black panel, and that is the location for the replaceable resisters should you over power the speakers and one doesn't sound as loud as the other (I'm doing this weekend) Also if you want to attentuate the tweeter or mid, you wilson dealer can change these values.. These are amazing speakers the more I listen to them and learn about them.
Stop by your dealer and have him show you how to remove the watt from the puppy there.. you will feel alot better doing it once on his.. but it really is no big deal other than realizing how heavy they are!
