This is the problem:

I have dug out a set of Ozaki 4.1 speakers (carefully all kept
together in a plastic bag).. but not with their power adapter.

I have a collection of power adapters, and they are never marked up
with the device they came from.... I also have a multi-settings power
adapter that I can use to test these speakers.

There is nothing on the speakers to indicate what the power adapter
should provide. Though I have another set of older twin speakers
(Creative) and they require 9v.

I was wondering what settings I could try to see if I can get the
Ozaki set tested.

The Ozaki pdf manual that I have managed to locate does not go into
these details.

Thanks
Thy 'em on 6V. If they work, fine. If they sound crap try 9V. And so on.
The correct voltage will be two steps below the one where they start
to smoke.
