A few days ago I have tested my FP14000 with my friend Mauro that is the real engineer of the experiment.
We used an oscilloscope, a frequency generator, an ammeter and a voltmeter connected to the mains and to the amplifier.
Unfortunately, I do not have a resistance to 6 kw or something like that, so I decided to use my hornsubs that are equipped by a RCF LF18N401 (1200 watt rms , 2400 watt program 8 ohm).
Honestly I could not believe that FP14000 was so strong like Johnson says…. then I decided to set my amplifier at 195v (VPL) for the experiment. I tell you now that the result is amazing!! The thing that isn’t amazing?! One of my transducers is burned… the coil is gone.
Based on the parameters collected we can say that the ampli can easily supply 1418 watt rms for channel (8 ohm) without exceed the vpl light. Getting the clipping light may be it can go up to 2kw for channel at 8 ohm but We could not push to the maximum to preserve the woofer…Nevertheless, as I said, I have burned one..
The first few seconds the ammeter has shown 20 Ampere which means that we arrived about at 4kw, considering that the efficient is about 90%, like our data shows. After the ammeter shows about 16 ampere.
Some parameters of our test:
VPL 195v; VPL mode Hard; gain 41db; 2 channels 8 omh;
Frequency 50 hz; electric system 220v, 16 A;
I made a short video of the test, for obvious reasons I deleted the audio: http://www.youtube.com/watch?v=5-Bm_JFmjXU&feature=youtu.be
In the coming days I will post all the results data. A special thanks to Mauro!!
Finally, sorry for my bad English!!
