Skybone Posted June 28, 2015 Share Posted June 28, 2015 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.

[/quote] 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..?

mikebass84 Posted June 29, 2015 Share Posted June 29, 2015 Buy another 4x10 at 8ohm. Stack them. 4ohm Quote Link to comment Share on other sites More sharing options...
