Yes, the 104 was a big step up from the 100 loudspeaker. The 100 uses an armature connected to the cone, driven by a coil and horseshoe magnet - it's poor on bass AND treble, but worked well enough for many. The 104 is a moving coil speaker (the first one made, I believe), with a powerful electromagnet - much better for music reproduction.
