Abstract
The term “monitor loudspeaker” is loosely applied to almost any loudspeaker used for monitoring recorded product at any stage in sound production or postproduction. In a more restrictive sense the term applies to products that are widely accepted in monitoring operations and have, to some extent, been modified or designed to meet a list of performance attributes determined by recording and broadcast engineers. Broadly speaking, those attributes are:
-
1.
Extended bandwidth. The range from 40 Hz to 16 kHz (± 3 dB) represents the minimum acceptable for a full-size monitor. Smaller monitors should be just as flat across their passband, but the allowable LF limit may be raised somewhat.
-
2.
Flat frontal angle response. The bandwidth stated in item 1 should be uniform over a horizontal beamwidth of ± 15° and a vertical beamwidth of ± 5°, both with respect to the forward axis.
-
3.
Controlled power response. The DI of the system should be free of any deviations exceeding ±3 dB over the range from 250 Hz to 10 kHz.
-
4.
Accurate time domain response. The group delay of the system should fall within the Blauert and Laws criteria (see Section 5.7).
-
5.
Accurate stereophonic imaging. If the loudspeaker is not inherently of horizontal mirror image symmetry, it should be offered in separate left and right models so that symmetrical listening geometry can be achieved.
