Glossary K-O
Le
The voice coil inductance of the speaker (transducer) or subwoofer measuredl in mH.
Linkwitz-Riley Network
Type of crossover filter with a special shape and roll off. The more common Butterworth has its cut off frequency at the -3db point. This point is 0.707 the amplitude of the pass band. The Linkwitz-Riley has its cut off frequency at the -6db point.
Magnet
A ferrite material charged to maintain a constant magnetic field. Used as the motor for speakers (transducers) and subwoofers.
Magnetic Gap
The space between the inside diameter of the top plate and the outside diameter of the pole piece of a speaker (transducer). The tighter the gap (less distance), the greater the efficiency of the motor structure.
Midbass (Speaker)
A speaker (transducer) that is optimized to reproduce the audible bandwidth between the midrange and subwoofer.
Midrange (Speaker)
The speaker (transducer) that plays the middle range of frequencies of the audio bandwidth. This is the most important frequency range for speech intelligibility.
Mmd
The mass of the speaker cone (Diaphram) typically measured in grams.
Mms
The effective mechanical mass of a speaker (transducer) or subwwofer including air load measured in grams
MP3
Originally developed in Germany in 1991 by the Fraunhofer Institute, MP3 (MPEG Audio Layer 3) is an audio compression technology that is part of the MPEG-1 and MPEG-2 specifications. MP3 compresses CD quality sound into significantly smaller file size with near the same music fidelity.
MP4
MPEG-4 is a file format for compressed video.
No
The efficiency of the speaker (transducer) or woofer measured in percent.
Octave
The frequency bandwidth ranges defined by the interval of half or double of the starting frequency.
Ohms
The measurement unit that defines electrical resistance.
