Cab Rewiring?

Does anyone know if it would be possible to rewire a cab to a different Ohm rating?

For example, if a 4 x 10 cab has an 8 ohm rating (ie, 4 x 8 ohm speakers), would it be possible to rewire it so that it would become a 4 ohm cab, without changing the speakers?

Just curious. :)

There are only a certain number of ways to connect speakers in such a cab. Assuming, then, all speakers to be 8 ohm, we can have any of these 6...[list=1]
[*]4 in parallel = 2 ohm
[*]3 in parallel,1 in series = 10.67 ohm
[*]2 in parallel, 2 in series = 20 ohm
[*]2 in parallel, 2 in parallel = 8 ohm
[*]1 in parallel, 3 in series = 6 ohm
[*]4 in series = 32 ohm
[/list]

... and that's it. The only solutions which enable each speaker to receive the same power are 1, 4 and 6. All the others have unbalanced sharing of the power by the speakers.
Does this satisfy your curiosity..? B)

[/quote]As explained above, no. And if the reason is the usual 'to get all the watts out of my amp', it wouldn't matter anyway.
