In its original formulation, Ambisonics assumed plane-wave sources for reproduction, which implies speakers that are infinitely far away. This assumption will lead to a pronounced bass boost for speaker rigs of small diameter, which increases with Ambisonic order. The cause is the very same proximity effect that occurs with directional microphones.
www.infintyspeakers.com. Infinity Systems is an American manufacturer of loudspeakers founded in Los Angeles in 1968 and headquartered in Stamford, Connecticut. [1] Since 1983, Infinity has been part of Harman International Industries, which became a subsidiary of Samsung Electronics in 2017. Infinity produces packages for a range of audio ...
L-Acoustics V-DOSC/dV-DOSC line array at a concert. NEXO STM M28 Line array at EXPO Festival. A line array is a loudspeaker system that is made up of a number of usually identical loudspeaker elements mounted in a line and fed in phase, to create a near- line source of sound. The distance between adjacent drivers is close enough that they ...
This system has a characteristic mass and stiffness, and a resonant frequency at which the system will vibrate freely. This frequency is known as the "free-space resonance" of the loudspeaker and is designated by F s. At this frequency, the voice coil is vibrating in the speaker's magnetic field with maximum peak-to-peak amplitude and velocity.
The left and right surround speakers in the bottom line create the surround sound effect. 5.1 surround sound ("five-point one") is the common name for surround sound audio systems. 5.1 is the most commonly used layout in home theatres. [1] It uses five full bandwidth channels and one low-frequency effects channel (the "point one"). [2]
A transmission line loudspeaker is a loudspeaker enclosure design which uses the topology of an acoustic transmission line within the cabinet, compared to the simpler enclosures used by sealed (closed) or ported (bass reflex) designs. Instead of reverberating in a fairly simple damped enclosure, sound from the back of the bass speaker is ...
LS3/5A. The LS3/5A (each element pronounced separately, without the stroke) is a small studio monitor loudspeaker originated by the BBC for use by outside broadcast vans to ensure quality of their broadcasts. The speaker concept set out transparent and natural sound as the goal, and the achievement of the result is widely acknowledged.
Speaking tube. A speaking tube or voicepipe is a device based on two cones connected by an air pipe through which speech can be transmitted over an extended distance. Use of pipes was suggested by Francis Bacon in the New Atlantis (1672). The usage for telecommunications was experimented and proposed for administrative communications in 1782 by ...
