Where can I get electrical schematics, circuit diagrams for audio devices (JBL and others)?

[Edgar]

I think about buying a pair of JBL 708p aktive speakers. And I plan to use them in a country were they are not officially sold. If there are any issues then it would be good if an electrical engineer could look at those things. And then it's obviously good to have a circuit diagram (or is electrical schematic a better term?).

Are circuit diagrams for JBL and other brands available? Where? I expect they are not free and that is no problem.

Thanks

I too would be interested in this.
