Mike - if you have a strong friend who can help, and you read the manual very carefully. The step by step instructions are in there. I couldn't wait. My dealer will be checking my work in a week or two, but we couldn't coordinate schedules for a few weeks and I wasn't waiting!
In fact, I highly recommend you do it yourself so you know all the ins and outs of your new speakers. Learn about the Zone of Neutrality. Get some blue painters tape, a laser tape measurer and a regular old fashion tape measurer and with the help of strong friend, you are good to go.
Just make sure you peal the protective wrapping off the speakers and midrange and tweeter units VERY VERY SLOWLY and from the top down. This will be the most time consuming.
Personally, I would hate not to know how to do everything myself. What if I move homes or something?
Anyway - up to you. I'm also here to help. If you don't have my number, PM me.
