Ok here it goes.....
Let's say I have an amp in the which output is 25 Ohms that I would like to use to power a self built cabinet.
How could I do this?
Wire 3 8 Ohm Speakers in Series and add a 1 Ohm Resistor? Is that completely nuts? Is there any better way (Besides telling me just to get a different amp lol) to do this? Thanks in advance!
3 x 8 ohm speakers in series will do fine. I wonder why your amp has such an oddball impedance.
Indeed.
SOlid state amps have no inherent load impedance, they are rated to a minimum impedance. I have never seen an amp with a minimum impedance load remotely as high as 25 ohms. I also cannot imagine a tube amp with a 25 ohm output winding.
What I CAN imagine is a PA amp with 70v and 25v outputs along with the 8 ohms and whatever. In those cases - like old Bogen amps - that 25v is intended for a constant voltage wiring scheme. It is not 25 ohms though.
Just what on earth do you have there?
