Can you post the circuit diagram of jbl creature ii?

I looked and the only thing I could come up with is to e-mail JBL and order a new one. Radio shack, Best Buy, or Futurehsop might be able to help but you have to call them with the model number or go to the store and check it out. Here's the link to JBL if you want to order a new one.

Sorry, wish I had a better answer but there isn't much out there for this.

Yes it can be replaced and your system will be as good as new afterwards.

To get an idea of the work involved: http://www.audiofriends.nl/pdf/refoaming.pdf

There are several companies selling these so called surrounds. There are foam and rubber surrounds. Stick to the same material as you may otherwise significantly alter your system's sound. Just google "speaker repair" or "speaker surrounds" and you will find several. You can ask them to repair your speakers (which may be fairly expensive) or you can order the surrounds and glue (you can not just use any glue) and do it yourself.

I have done such repairs a few times myself and it is absolutely not difficult.

Good luck.
