I'm with Maninder on speaker volume, although DSP chips, as Manuel would have said, I know nothing lol. I had a nice transistor radio with a big speaker many moons ago at uni when battery tech was inferior and rechargeables were pretty poor. I'd play it fairly quiet, but my room mate would wack up the volume when I wasn't there and flatten the battery in no time. I'm sure it would have run for days though on a fully charged car battery.
