- ACcording to the person at Sun with whom I spoke, it is not clear that
- the Rev 4 speaker box really solves the problem. They are currently
- in the process of doing a serious engineering evaluation of the
- situation. My advice is top call Sun and have them add you to the
- list of customers to be notified of the results of the aforementioned
- evaluation. It seems like a lot of trouble and expense (for Sun) to
- start shipping a bunch of customers the Rev 4 speakerbox if it doesn't
- completely solve the problem.
