In our previous bot we just used two ordinary rather heavy 100 watt
RMS car speakers attached directly to the inside of the armour (with
holes drilled in the armour to let the sound through). We didn't do
anything physically to improve the sound... the speakers were just
about loud enough, especially for midrange sounds.

But the design of the new robot is a bit ambitious and heavy car
speakers like those are a serious strain on the weight budget so
they'll have to go...
