AMM-1 Doesn't seem accurate, anyone else?


Recommended Posts

Okay I have not had much time to play with the meter but like any other shop we wanted to run it and see some amps. While only getting to test 2 amplifiers 1 is a Kenwood KAC-5206 60 RMS x 2 130 RMS Bridged. Testing on a Focal subwoofer we are only achieving 27 watts.

Okay so no big deal maybe its sensitive to smaller power readings. Next amplifier up is a MMatts M600.1 USA made amplifier 1 Ohm version. Tested out at 217 Watts? This was the highest we obtained and that was at 43 Hertz. Something has to give or any advice. The Kenwood was tested on a display the MMatts was tested in a vehicle. Any help or responses would be great. Thanks.

did you do a sweep.... and what was the power factor at on these tests... you want to find the reading that has the highest power factor... if the power factor is at 20% it does not matter if its a dc 5K its not going to tell you anything close to 5K... ect... cabin gain and impediance rise play a huge factor

Are you sure you didn't fuck up your wiring?

Krakin, are you some sort of mad scientist?

I would have replied earlier, but I was measuring the output of my amp with a yardstick . . .

What you hear is not the air pressure variation in itself

but what has drawn your attention

in the two streams of superimposed air pressure variations at your eardrums

An acoustic event has dimensions of Time, Tone, Loudness and Space

Everyone learns to render the 3-dimensional localization of sound based on the individual shape of their ears,

thus no formula can achieve a definite effect for every listener.

The numbers don't lie.

Even I don't want to believe those amps are that over rated! Lol

Who says that's what it is, he could be rising to 10ohms for all we know.

That being said a lot of people's definition of "music" is a clipped 30 hz sine wave with some 80 IQ knuckle head grunting about committing crimes and his genitals.

It's acoustics. If it is a thing it affects any other thing.
