2023年9月28日 · A high damping factor (which requires low output impedance at the amplifier output) very rapidly damps unwanted cone movements induced by the mechanical resonance of the speaker, acting as the equivalent of a "brake" on the voice coil motion (just as a short circuit across the terminals of a rotary electrical generator will make it very hard to ...

2017年1月17日 · Damping factor = load impedance / source impedance Obviously, this will vary by frequency as the speaker load changes with frequency. But generally what's needed is a small denominator, a low output impedance, which most negative feedback based amps have.

2016年3月15日 · A damping factor of 100 or more results in well under 1 dB variation for most speaker. Note low output impedance (or not), and thus high damping factor is often at least partly the result of other design choices. Higher feedback to provide lower distortion will also lower output impedance (and raise DF).

2020年6月5日 · Amplifiers with low damping factor values, say in the range 10 to 20, will have a large effect on the frequency response of typical loudspeaker systems. The frequency response of the amplifier is modified by the variation in the impedance …

2020年4月10日 · A high damping factor means the amplifier's output impedance is very low compared to the load (speaker) impedance. And it makes the amplifier act as a "voltage source" where the voltage is independent of the load.

2024年3月1日 · "Damping factor" is a marketing spec and is, frankly, ill-defined, so of course he uses a worst-case definition. A better spec would be "source impedance," and if we follow the rule that the source impedance should be <1/10 the speaker impedance, a speaker like that should be paired with an amp having a source impedance of 0.26 ohm (which is a ...

2018年7月21日 · Damping factor is only an argument with old or old style speakers and amps, where it's an important factor that is often overlooked. But with modern tech speakers and amps, it became a non-issue as all are expected to be tuned for high damping factors and frequency independent behaviour due to that.

2007年10月1日 · Damping Factor Defined. Scientifically speaking, Damping Factor is the ratio of the resistance component of the loudspeaker’s impedence to the resistance component of the amplifier’s output impedence. This number is used to determine how well the amplifier is able to control the motion of the loudspeaker.

2021年6月5日 · The damping of a speaker driver is determined by the sum of all resistances in the path, which comprises of the voice-coil resistance (dominant factor), any XO components in series, and the amp output impedance (negligible). Thus, for the damping it does not matter if the woofer sees its own DC...

2011年1月13日 · Re: Damping Factor - Actual listening tests? The damping factor spec is mainly a measure of output impedance, mostly reduced by large amounts of negative feedback but that doesn't tell the whole story about how much current the amp can deliver, when, and how the amp will behave dynamically.
