You can check with a 1.5v battery if you can see the cones of the
speakers, connect the battery to the speaker wires one way and the
cone will move in, the other way and the cone will push out but don't
keep the batt on for too long though.

Just to add convention has it if the cone moves out the battery is
connected correctly - ie positive to positive.
