Over here, our watts are metric. You guys are still using imperial watts.

Yeah. Watts up with that?

 

Use RMS spec for both amp and speaker spec. If the manufacture can’t provide that, then that is suspicious.
Choose a different manufacturer.

If you try to do a root mean square average on power, you get the wrong answer. Root mean square averages only work on parameters that need to be squared to give power.

In text books, one usually find the explanation of the root mean square average alongside a sinewave, with a derivation of the DC voltage that will result in the same dissipation in a resistor. The association between rms and a sinewave, has somewhere been misconstrued that rms is a property of sinewaves. So "rms power" has be a misnomer for sinewave power i.e the power dissipated in a certain load resistors by the largest amplitude the amplifier can produce at a given level of distortion. In order to make the figures better, use a higher level of distortion.

Yes! This is why I hate the term "RMS Power". It is meaningless.

I don't think it's meaningless when used in the correct context. I've used power amps to simulate equipment conditions for operational bench testing.

What would be the correct context for a meaningless term?

So, then, define "RMS Power". Show me an equation.

Power requirements for wireless transport robots where the power drive signals are sine waves being convert to DC power.

Do you mean that the drive signals are voltages?

If the power were a sinewave, then there would be as much power being transferred to the robot in the positive going half cycle as was being transferred from the robot back to the power supply in the negative going half cycle, and the average power transferred would be zero.

 

I chose the Sony. Excellent sound for the price, especially through the Beringer XR-18 mixer.

 

Sony's amps are a little overpriced IMHO ... but their speakers are among the best commercially available

$250 is pricy for 100x100?

The first component system I owned (a Fisher "Studio Standard") cost me $1,862 in 2026 dollars.

 

Fisher was one of the most popular brands back then ... along with Marantz, Pioneer and Alpine ... although the last two were mainly for automotive sound systems

Yup. I installed a number of them for friends.

So did I! ... it was hard work and I only accepted payment in cases of beer

 

I built my first stereo amp (actually it was a 4-channel quadraphonic sound system) based on the Sinclair Z.30 amplifier modules. I too went on to building stereo systems for friends.
