A guitar speaker is a loudspeaker, usually 12" in diameter, which produces less than full frequency response. A guitar speaker produces some distortion when driven hard. Early guitar speakers such as by Celestion handled 15-25 watts.
The magnets of a guitar speaker are usually made from alnico, ceramic, or neodymium. Alnico magnets are expensive, so top-of-the-line alnico guitar speakers such as the Fane AXA Series, Eminence Red Fang, Jensen Jets Blackbird, Celestion Blue or the Brown Soun Tone Tubby are several times the cost of a typical ceramic-magnet guitar speaker.
A speaker cabinet for guitar can be open-back or closed-back, along with variations such as a semi-open back 4x12 cabinet, which may have a baffle deflecting two of the four speakers. A 4x12 speaker cabinet has four 12" speakers; a 2x10 speaker cabinet has two 10" speakers. Bass cabinets often have multiple different-sized speakers.
Bass guitar speakers are often 8" or 10" in diameter. The standard sizes are 6 1/2", 8", 10", 12", and 15".
A guitar speaker driven hard produces complex dynamics. A guitar speaker cabinet simulator circuit attempts to emulate the complex frequency response of a guitar speaker. A common microphone to capture and shape the dynamics of a guitar speaker is the Shure SM57 or the Sennheiser 421.
Well-known guitar speaker manufacturers include Fane, Jensen, Celestion, Eminence, Electro Voice, JBL, Weber, and A Brown Soun.
