The part of the woofers metal Basket or frame on which the Magnet structure is mounted.

In receivers, a display may be lit from the rear to create better visibility under a wide range of ambient light conditions.

A flat panel that divides the front and rear sound waves produced by a woofer. Sometimes baffle is used to mean an enclosure or the front panel on which the speaker is mounted .

Audio line signals require two conductors. In an unbalanced line, the shield is one of those. In a balanced line, there are two internal wires plus the shield. For the system to be balanced requires o [..]

An enclosure that is specifically tuned to give maximum energy to a very limited range of frequencies, usually the lowest. In this arrangement, the woofers are fully enclosed in the box with the sound [..]

A low-pass and a high-pass filter in series, acting together to restrict (limit) the overall bandwidth of a system. Many audio amplifiers and processors, having switches labeled as "Rumble&am [..]

A filter that has a finite passband, neither of the cutoff frequencies being zero or infinite. The bandpass frequencies are normally associated with frequencies that define the half power points, i.e. [..]

Abbr. BW The numerical difference between the upper and lower -3 dB points of a band of audio frequencies. Used to figure the Q, or quality factor, for a filter.

A speaker magnet material made from an alloy with iron and barium for improved magnetic strength.

The metal frame structure of a standard dynamic loudspeaker. In larger, heavier speakers, this may be made of cast metal for extra strength and rigidity. All the other elements of the speaker are moun [..]
