Dear all,

One of my students has asked me if it is possible to power a high
quality speaker from a car battery or any other portable sources. And
if so how long would the battery last for? I have no idea about this
but someone here may have a suggestion. It is for an installation in
the middle of a park in Switzerland.

Best,

Peiman

is one. There's a high end "clean" version out there as well. When I
remember where I saw it I'll pass it on.

if you can, don't use an inverter and grid-powered amp - the power
conversion will be lossy and possibly noisy. rather, get as many car
hifi amps as you need, and use whatever passive speakers you have.

best,

Dave Tipper and Richie Warren's cars can drown out a music festival...
powered on 6 batteries according to Wikipedia (most of the sources are dead
links though).
