Anyone who is a car buzzer or who has passed it by will know what the subwoofer is. Subwoofers are used to create this great and deep feeling of bass, which is usually among most of the average speakers. Subwoofers are not only used in car sounds but also in home movies to give the perfect bass in a small area, such as a room or a car.
Although subwoofers may seem simple enough, they are not really as simple as they seem. Over the years, they have been researched, tested and developed to get the best sound from them. However, like each product, there are different levels of quality subwoofers and types that are suited to different requirements and conditions.
The first company to promote the appropriate subwoofers was Acoustic Research (AR), which in 1954 introduced an AR-1W system that could prolong its bass in 20hz without any help from alignment and the literal woofer was effectively locked in a fence. The AR-1W was unmatched in design for many years, and in fact it is still very impressive on modern subwoofer design using acoustic suspension. AR-1W was a subwoofer deal that could easily be installed in pairs in pairs, unlike those high-end speakers that had previously been on the market.
Dr. Harry Olsen was also a major part of the design of sound systems we have today. In 1930/40 he was the first to conclude that the speakers need to have their back and front, as the sound waves from the back will interfere with the front. He also designed the passive oven, which was designed to replace the Vent system, which had a large number of faults at the time. The ventilation design needed a large channel to prevent wind noise, which often meant that the channel was bigger than the air itself. Olsen, instead, used a diaphragm with a suspension, as the mass was equivalent to the airspace in the air, so it was much smaller and far more efficient than other designs.
James Novak Jensen, a highly talented research engineer and mathematician, had to come up with bass reflex design. With his knowledge as a mathematician and experience as an engineer, he could create and combine ideas about what is today known as a closed, airy and passive speaker system.
Although considered essential part today, bass extensions were still a relative of luxury in the 1950s and 1970s. The film companies were the main authors interested in bass boost, which was first used in business for the massive blow, Star Wars.
In the last century, these master's and mathematicians have probably influenced Outstanding acoustics available in bingo and home events today.
