Any idea how much smoothing they put on that graph? It doesn't look like raw data!
How about "±1.25dB limits all the way from 80Hz to 16kHz" in room, as measured by John Atkinson. I would take the extra range with slightly greater tolerance.
The smoothing used here is 1/3rd octave.
A bit of background on the measurements. You guys probably all know that an octave is composed of 12 notes. Take the frequency of 64 hertz. That is approximately a bass C note. Pop up to 128 hertz and you have an octave, or a doubling of frequency. Drop down an octave and you again have a C note. This one is at 32 hertz.
Smoothing is used for a few reasons. There are spikes in the frequency response of anything you are listening to. If they are short in frequency width and not more than 3 to 4 db they are not that unpleasant. But the graph doesn't look good.
A frequency response graph coupled with a high resolution impedance graph presented along the same linear scale will be very revealing of what is happening. You will notice that there are correlations between impedance spikes or drops and the frequency spikes and drops. These are points where there are mechanical problems showing there ugly little heads. No amount of EQ or shaping will eliminate these.
Much practice in the art of loudspeakers has taught me that when something is 24 db down, it is not really an issue at any sane volume.
That is a benchmark point to keep any unwanted sonic trash.
The measurements that are not normally shown is the intermodulation distortion figures. This is something we do not like listening to. And is something that good design practice can mitigate.
Yes we will be showing this figure as well.
At Funk Audio we use 1/6th octave. That's the threshold in the midrange that really matters, and it is much more revealing of the true nature of the beast.
Someone posted a few blurbs about the amplifiers.
Short but sweet.
I went to 8 different manufacturers, and surveyed their products. I investigated their means and methods of how they put together their products and found the one we are using. It is world class. The best methods are used from power input to sound output. The finest power supply engineering and from there they just get better. They are engineered to the tops of their heads so to speak. Bullet proof. In engineering speak they are designed for a 90% duty cycle. Almost full power output full time. Our heatsink size used is 300% greater than worst case scenario. You will never be stressing these amplifiers.
Try that with your favorite megabuck power amp. They let out their smoke. And they stop working. I learned that while working as a electronics repair tech back when I had hair. All electronics run on smoke. When the smoke gets out they stop running.
As a reality check you listen to loud music in the low 90db at listening position. If you are about 6 to 8 feet from your speaker you need a one meter volume of 96 to 99 db. If you keep 1% harmonic distortion as your threshold of audibility on pure tones not that many loudspeakers are perfectly capable of meeting this benchmark. Our offering is among the few that is.
So no a loudspeaker does not have to be the weak link in the audio chain.
We will be posting all relevant specs when this product becomes fully implemented. It is still a pre-release.
It is Funk Audios policy not to publicly release performance specs on pre-release full range loudspeakers as they are subject to revision and improvement.
