What is the difference between a two way and three way speaker
🔄 Click to see definition
Definition1/15
A two-way speaker has two speaker cones built into one speaker
assembly: one cone to generate lower-frequency sounds and one cone
to generate higher-frequency sounds. The low-range speaker cone is
larger, the high-range cone is smaller. In car speakers, the
low-range speaker cone usually occupies most of the area of the
speaker, and is made from a light-weight, paper-like material,
sometimes painted black, sometimes gray. A three way speaker has
three speaker cones built into the assembly, an additional cone for
mid-range frequency sounds.

Electric field lines can either form closed loops or they can
start and finish on isolated electric charges. Magnetic field lines
always only form closed loops.
