Construction and testing

Speaker design is considered both an art and science. Adjusting a design is done with instruments and with the ear. Speaker designers 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 developers (such as Bose) eschew the sole use of anechoic chambers in favor of specific standardized room set-ups designed to replicate likely real-life listening conditions. Some of the issues in speaker design are lobing, phase effects, off axis response and time coherence.
