Get a electric car with some decent range like a Tesla and put some solar panels on your roof. Don’t contaminate the earth for your electricity and don't fund the energy wars for some stoopidass car's gas.
A speaker? Well. Whatever you speaker you've got at the moment can't be all that bad, eh dude? Treat your room instead. Don’t be afraid of construction. Construction and treatment is like kryptonite for many audiophiles, which is why they have sht sound.
