or perhaps both.

yes, if it's loud enough for most of the world to hear i would expect some media coverage.

I intend to use an amplifier.

still might not be loud enough

Possibly.

how powerful an amplifier do you intend to use?

I intend to have the speakers in the united states while I speak, and I expect to hear them, so quite powerful

you'll probably need quite a powerful amplifier too.

Indeed.

i don't think it'll work, it'll be too distorted, and drowned out by echoes.

Oh. Maybe I'll have to just set up a worldwide network of speakers.

that would stand more of a chance

Maybe I'll just do it next time I see Pliny.

that would be simpler

Indeed it would.
