At the very least, such a loudspeaker may be 2-way employing a woofer (or mid-range/mid-woofer) and a tweeter. Higher end loudspeakers may be 3-way or even 4-way. For the sake of this article and simplicity, a 2-way speaker system will be assumed - consisting of a woofer and a tweeter.
This same plane-wave assumption makes it possible to vary the distance of speakers within reasonable limits without upsetting the correct function of the decoder, provided that the difference is compensated with delay, the power is adjusted for uniform loudness at the center, and that per-speaker near-field compensation is used.
With ordinary loudspeakers, a single amplifier can power the woofer, mid-range and tweeter through an audio crossover, which filters the signal into high- medium- and low-frequencies (or high- and low-frequencies in 2-way speakers) – a mechanism that protects each driver from signals outside its frequency range. However, the passive crossover ...
Portable magnetic-loop cave radios have been used by cavers for two-way communication and cave surveying since the 1960s. [1] In a typical setup the transmitting loop, consisting of many turns of copper wire, is oriented horizontally within the cave using a spirit level, and driven at a few kHz. Though such a small antenna is a very poor ...
XI (2-way) - 23x12x11" - $80; XII (3-way) - 25x14x11" - $139; Some of these early 3-way models featured 10" and 12" woofers manufactured by Jensen ("Flex-Air") and CTS (Chicago Telephone Supply), 5" whizzer cone squawkers manufactured by Philips Electronics of the Netherlands, and 2" and 2.5" cone tweeters by Peerless of Denmark. [22] The ...
A typical top-end speaker, driven by a typical 100watt power amplifier, cannot produce peak levels much above 105 dB SPL at 1 m (which translates roughly to 105 dB at the listening position from a pair of speakers in a typical listening room). Achieving truly realistic reproduction requires speakers capable of much higher levels than this ...
A speaker at former President Trump’s Madison Square Garden rally on Sunday spent a portion of his time attacking Puerto Rico, drawing backlash from Democrats and the Harris campaign. Comedian ...
Acoustic lobing refers to the radiation pattern of a combination of two or more loudspeaker drivers at a certain frequency, as seen looking at the speaker from its side.In most multi-way speakers, it is at the crossover frequency that the effects of lobing are of greatest concern, since this determines how well the speaker preserves the tonality of the original recorded content.
