It was fun! At times frustrating but well worth it. I was concerned with same issues, Steved is mentioning, and used extensive bracing (check North Creek Music) and a lot of lead sheet inside the "Watt" cabinet to mimik density and weight of the original cabinet materials. X-over is easy but parts can be expensive. If you have any more questions you can e-mail me.
