Testing of dynamic loudspeakers


The nature of speaker design is considered both an art and science. Adjusting a design is done with instruments and with the ear. Speaker designers will use an anechoic chamber (essentially a room with soundproofing that inhibits any reverberation or echo) to ensure the speaker will perform the way it is intended to. Some of the issues in speaker design are lobing, phase effects, off axis response and time coherence.
