Polk Audio was founded by Matthew Polk, George Klopfer and Sandy Gross in 1972. The three first met one another while attending classes at Johns Hopkins University in Baltimore . After graduating in 1971, the team collaborated on producing a sound system for a local bluegrass music convention.
"We believe that the sound of music, unamplified, occurring in a real space is a philosophic absolute against which we may judge the performance of devices designed to reproduce music." Subjectivists rely on demonstrations and comparisons but believe there are problems in applying double-blind methods to comparisons of audio devices.

The transmitter connects to the audio output of any audio devices such as hi-fi equipment, televisions, computers, MP3 players, etc. An RCA plug is normally used to achieve this. The receiver is positioned where the listener wants the sound to be, providing the freedom to move the wireless speakers around without the need of using cables.
From about 1900 to the 1950s, the "lowest frequency in practical use" in recordings, broadcasting and music playback was 100 Hz. [9] When sound was developed for motion pictures, the basic RCA sound system was a single 8-inch (20 cm) speaker mounted in straight horn, an approach which was deemed unsatisfactory by Hollywood decisionmakers, who hired Western Electric engineers to develop a ...
An audio analyzer is a test and measurement instrument used to objectively quantify the audio performance of electronic and electro-acoustical devices. Audio quality metrics cover a wide variety of parameters, including level, gain, noise, harmonic and intermodulation distortion, frequency response, relative phase of signals, interchannel crosstalk, and more.
A soundbar, sound bar or media bar is a type of loudspeaker that projects audio from a wide enclosure. It is much wider than it is tall, partly for acoustic reasons, and partly so it can be mounted above or below a display device (e.g. above a computer monitor or under a home theater or television screen).
For example, mounting a tactile sound transducer in a chair or couch in a home cinema or video game setup can give more of a sense of "being there". For such use, the transducer is often connected to the LFE channel of an A/V receiver. Tactile sound is often used in combination with a subwoofer so that low frequencies can be both felt and heard ...
