The system of High fidelity speakers generally includes digital audio signal sources like CD players; digital audio broadcasting, digital audiotape and HD radio tuners and amplifier. Infact, they also include components such as television, projector, DVD player and multi channel loud speakers. These together are often known as home theaters that are quite common in every home now a day.



These high fidelity speakers are not the new ones. The story began in 1920 with the introduction of electronic amplification and other sound reproducing systems like microphones. All the acoustically recorded disc records were getting replaced by the electrically recorded records, which proved to have better frequency response as compared to the disc records.

Meanwhile with the rise of radio, increased the popularity of loudspeakers and amplifiers. And thus radio receivers started using loudspeakers and electronic amplifiers to produce sound but phonographs remain mechanical and acoustic. But later, electronic phonographs were introduced which were played through listener's radio.

Specifically speaking, there was an audio revolution going on which resulted in the development and popularity of the sound producing equipments. However, came 1930s and with it sound films developed. The movie industry felt that better fidelity, i.e., optical sound, better amplifiers and exclusive speakers can bring exciting effect to the sound track. The motion picture companies began developing amplification and loudspeakers to fill the theaters with high quality sound system.

This experimentation gave birth to woofers and tweeters, the different sections of loudspeakers for low and high frequencies. This development finally resulted into better fidelity sound equipment that can be used in homes too as homes equipment. But the cost of the whole equipment was high and not possible to own for people with average income.

After World War II ample technological experimentations and innovations took place that developed the condition of the audio system, especially the home audio system. Before there were only AM radio, but then came FM radio with wide audio bandwidth and better signal upgradation. Lower speakers were amplified and distortion free amplifier with wide dynamic range were used in the theater systems, sound reinforcement and then developed radio sets. Not only this, these speakers were attentive to higher frequency response and had higher power output capability.

The development story of the high fidelity speakers also includes innovations for musical artists. The reel-to-reel audio tape recording helped the artists make and distribute recordings with better fidelity.

Next period that is from 1950 to 1960 was the golden period for high fidelity speakers as they became popular with the audio manufacturers who used them as a marketing term to sell the equipments, which provide good quality sound reproduction. The system was later improved with the development of the Westrex single groove stereophonic record. Since then gradually the system of high fidelity speakers never looked back and are even now considered to be a highly accurate sound reproduction system.
