Acoustic Research was a Cambridge, Massachusetts-based company that manufactured high-end audio equipment. The brand is now owned by VOXX.Acoustic Research was known for the AR-3 series of speaker systems, which used the 12 in (300 mm) acoustic suspension woofer of the AR-1 with newly designed dome mid-range speaker and high-frequency drivers.
Villchur's speaker systems provided improved bass response while reducing the speaker's cabinet size. Acoustic Research, Inc. (AR), of which he was president from 1954 to 1967, manufactured high-fidelity loudspeakers, turntables, and other stereo components of his design, and demonstrated their quality through "live vs. recorded" concerts. The ...
Developed by Edgar Villchur in 1954, this technique was used in the very successful Acoustic Research line of bookshelf speakers in the 1960s–70s. The acoustic suspension principle takes advantage of this relatively linear spring. The enhanced suspension linearity of this type of system is an advantage. For a specific driver, an optimal ...
The two most common types of speaker enclosure are acoustic suspension (sometimes called pneumatic suspension) and bass reflex.In both cases, the tuning affects the lower end of the driver's response, but above a certain frequency, the driver itself becomes the dominant factor and the size of the enclosure and ports (if any) become irrelevant.
Henry Kloss (February 21, 1929 – January 31, 2002) was a prominent American audio engineer and entrepreneur who helped advance high fidelity loudspeaker and radio receiver technology beginning in the 1950s. [1]
A loudspeaker (commonly referred to as a speaker or, more fully, a speaker system) is a combination of one or more speaker drivers, an enclosure, and electrical connections (possibly including a crossover network). The speaker driver is an electroacoustic transducer [1]: 597 that converts an electrical audio signal into a corresponding sound. [2]
The company was founded as SWR Engineering, Inc. by its namesake, Steve W. Rabe. Rabe was known for his engineering work at Acoustic Control Corporation.After extensive research with top Los Angeles studio bassists, SWR released its first commercial product in 1984, the PB-200 hybrid tube/solid-state bass guitar amplifier.
Sources in front of the speakers can be rendered by concave wavefronts that focus in the virtual source inside playback area and diverge again as convex wave. Hence the reproduction inside the volume is incomplete - it breaks down if the listener is situated between the speakers and the virtual source.
