Extensive prototyping drove up the development costs of new designs, pushing them out of popular price ranges. Some loss of accuracy ("smearing" or "vooming" of low frequencies) was inevitable and the results were not entirely predictable. The existing state-of-the-art at the time of AR's invention was the bass reflex speaker, which boosted bass response for a given amount of cone travel by directing sound energy from the rear of the speaker cone through a port in the cabinet "tuned" for reinforcement of the direct signal from the front of the cone by the signal from the rear of the cone.Īmong the drawbacks of bass reflex design are the stringent design parameters required for accurate bass reinforcement, requiring high precision and at the time, large cabinets. The acoustic suspension woofer provided an elegant solution to the age-old problem of bass distortion in loudspeakers caused by non-linear, mechanical suspensions in conventional loudspeakers. Acoustic Research as an employer claimed equal opportunity and offered liberal employee benefits, insurance, and profit sharing to its employees. Patent 2,775,309, granted to Edgar Villchur and assigned to Acoustic Research in 1956.Įdgar Villchur's technical innovation was based on objective testing and research, most of which was made publicly available as documents, specifications, and measurements-all of which were then new in the loudspeaker industry. AR was established to produce the $185 (equivalent to $1,840 in 2021) model AR-1, a loudspeaker design incorporating the acoustic suspension principle based on U.S. (“AR”) was founded in 1954 by audio pioneer, writer, inventor, researcher and audio-electronics teacher Edgar Villchur and his student, Henry Kloss.
