Loudspeaker Impedance?. Archived from groups: rec.audio.tech () I have a question regarding loudspeaker impedance. It is normally rated as 8 Ohms. What does this mean? Is this the impedance magnitude at some frequency? I know that a dynamic speaker...

the phase angle, usually expressed in degrees. It should be noted that in the grand scheme of things, both the resistance R and the reactance X can take on any value, positive, negative or zero. However, in the case of loudspeaker impedance,...

can be readily observed in the deviation from the ideal model. In the ideal model, the impedance rise should approach and, eventually, reach a rate where the impedance doubles with each octave. Further, you'll find that the phase angle of the impedance...

gain. There is no standard relationship between knob > position and gain. More to the point, since the actual power delivered to the speaker is a comples function of amplifier gain, input signal level, loudspeaker impedance vs frequency and the frequency...

of course. The second: They are quite right Loudspeakers have an impedance that is anything but straight. Depending on the frequency of the signal they may have an impedance that is significantly lower than rated. The amplifier needs to be able to...

Separation of variables is essential to an experiment >>attempting to measure the consequences of one effect. >>> The reason is quite clear. The question at hand is about loudspeaker> Doppler distortion. All known loudspeakers have copious amounts...

for the claim that 'properly designed amplifiers tend to sound the same'. Just be careful with idiosincratics pairs - e.g. SET amplifiers (is it a right example of properly designed amplifier??) with low impedance loudspeaker systems I personally am not...

What's all this gum-beating about "tests"?. Archived from groups: rec.audio.tech,rec.audio.misc,rec.audio.opinion,aus.hi-fi () Is somebody trying to peddle some "test" equipment on the audio newsgroups? I can't figure out the point of this discussion. Who...

guitar rig? >> Its a matter of level, and more importantly, impedance matching. Level for sure, impedance matching isn't so critical. The console will drive anytihng - the instrument amplifier directly, the mic side of a DI, a small loudspeaker (you...
