With the release of the first successful model in 1974, the Monitor 7, Polk Audio was gaining recognition in audiophile circles. Polk Audio used a two-way configuration on almost all its speakers, such as the popular Monitor 10 and Monitor 12, typically with 6.5-inch mid/bass drivers with rubber surrounds and passive radiators.
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.
"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.
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 ...
The first and simplest method is using a surround sound recording technique—capturing two distinct stereo images, one for the front and one for the back or by using a dedicated setup, e.g., an augmented Decca tree [20] —or mixing-in surround sound for playback on an audio system using speakers encircling the listener to play audio from ...
The effects of this can vary. If one digital device is used to monitor another digital device, this will cause dropouts or distortion in the audio, as one device will be producing more or less data than the other per unit time. If two independent devices record at the same time, one will lag the other more and more over time.
Smaller speakers are found in devices such as radios, televisions, portable audio players, personal computers (computer speakers), headphones, and earphones. Larger, louder speaker systems are used for home hi-fi systems (stereos), electronic musical instruments, sound reinforcement in theaters and concert halls, and in public address systems.
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 ...
