Ideally you would have your Authorized Wilson Audio Dealer help you with this process. They are equipped with all the tools and know how to do this safely and efficiently. You will need at least 2 strong people to do this safely. If you have the original crates your loudspeakers were shipped to you in, using these is ideal. If your loudspeakers were shipped with casters reinstall them and store the spikes for future use. Wrap your loudspeakers in soft blankets before putting the loudspeakers back in their crates to protect the paint. Use plenty of moving blankets to aid in protecting the loudspeakers and space around the crates, carefully move the crates to and into the vehicle you are using to transport your loudspeakers in. Take each step in this process slow and methodically and you will be successful in moving your loudspeakers to their new home.
You can find crates, tool kits, casters, and many other items that will help in our on-line store: http://parts.wilsonaudio.com/setup-care/crates/
Suggested tools: Gloves, blankets to wrap the loudspeaker and protect the area around the crates in the vehicle, casters (if available for your loudspeaker), original crates, loudspeaker tool kit, dolly, carpet or blankets to protect any flooring between listening room and vehicle, large vehicle to accommodate all crates safely.
