Focal 1028BE - protecting speakers for a move

Hi all,

Sorry if this has been asked/answered before, but I couldn't find a thread on this.  I'm moving to a new house, which is about a 10 minute drive away and need to pack up my Focal 1028BEs.  I don't have the original boxes or styrofoam.  Does anyone have advice on protecting the speakers for transport, especially the beryllium tweeters?  I'm planning on using a small UHaul truck.

Thanks!
