I am attempting to build a small distributed sound system form parts I have on hand. I have a mono utility amp that has both 70v output, a 4Ω output, and an 8Ω output.I have 6 ceiling speakers that are 8Ω. I know it would be best to have a transformer at each speaker but but that is not an option for this el-cheapo build. Help me under stand the best way to wire this system with the equipment that I have. The runs from the amp are not very long.
I know connecting a load lower than what the amp is rated for is very bad for the amp. So wiring these six speakers in parallel is out of the question that would see about 1.3Ω
As I understand it if I wire the speakers in a series the amp will see a load of 48Ω
and if I use a series/parallel wiring configuration the amp will see a load of 8Ω
I know the parallel configuration is out of the question. It appears that both the series and the series/parallel configuration are safe but which one is a better choice? I understand the end result of the series wiring vs the parallel wiring is that with the series the volume per speaker will be lower compared to the parallel configuration What would be the effective result of the series/parallel configuration.
I also understand that with the series configuration that attenuation at any speaker isn't possible. I'm OK with that but what would the effect be if I attempted to attenuate a single speaker in the series/parallel config?
Any help would be greatly appreciated.
Thanks,
Josh
