If a home hi-fi amplifier specifies 8 ohm or greater loads, care should be taken that loudspeakers with a lower impedance are not used, lest the amplifier be required to produce more current than it was designed to handle. Using a 4 ohm loudspeaker system on an amplifier specifying 8 ohms or greater could lead to amplifier failure.
Another popular format is four 10" or four 12" speakers. Some performers use two 4x10" or 4x12" cabinets. The largest guitar speaker cabinets have eight 10" or 12" speakers. A 4x12" ("four by twelve") is a guitar speaker cabinet containing four 12" speakers. Less commonly, some bass amp cabinets have multiple 8" speakers (e.g., the 8x8" cabinet).
American EIA standard RS-299A specifies that (or DCR) should be at least 80% of the rated driver impedance, so an 8-ohm rated driver should have a DC resistance of at least 6.4 ohms, and a 4-ohm unit should measure 3.2 ohms minimum. This standard is voluntary, and many 8-ohm drivers have resistances of ≈5.5 ohms, and proportionally lower for ...
The loudspeaker's nominal load impedance (input impedance) of is usually around 4 to 8 Ω, although other impedance speakers are available, sometimes dropping as low as 1 Ω or 2 Ω. However, the impedance rating of a loudspeaker is simply a number that indicates the nominal minimum impedance of that loudspeaker over a representative portion of ...
The first version of the Marshall stack was an amp head on an 8×12 cabinet, meaning a single speaker cabinet containing eight 12" guitar speakers. After six of these cabinets were made, the cabinet arrangement was changed to an amp head on two 4×12 (four 12" speakers) cabinets to make the cabinets more transportable. Some touring metal and ...
An external speaker jack is located next to the output tubes in the back and allows the signal to be heard out of both the amplifier itself and the speakers to which it is connected (which must have a 4- or 8-Ohm impedance). The DeVille features a 60-watt valve amplifier with three 12AX7 preamp valves and two 6L6 output valves. Its circuitry ...
Connecting a low-impedance load such as a loudspeaker (usually 4 to 8 Ω) to a line out will essentially short circuit the output circuit. Such loads are around 1/1000 the impedance a line out is designed to drive, so the line out is usually not designed to source the current that would be drawn by a 4 to 8 ohm load at normal line out signal ...
The most common nominal impedance for loudspeakers is 8 Ω. Also used are 4 Ω and 16 Ω. [20] The once common 16 Ω is now mostly reserved for high frequency compression drivers since the high frequency end of the audio spectrum does not usually require so much power to reproduce. [21]
