Running Benchmark AHB2 in bridged mode and 4 Ohm Speaker

I think Benchmark has done an excellent job of convincing everyone to buy two. Hail to marketing. All those who follow can do is quote the party line. We will never get them to understand.

Got a feeling there’s a couple of latent shills helping out too.

Cheers George

Likely indeed. The marketing guy did step in at one point. We really gave it a good shot.

Check out this thread claiming there is no RMS power.

 Read the banner at the top of the Wicki page and check out the references given below. especially #8. Then read all the compliants on the talk page. Im writing someting up.

to me

From Wikipedia "Audio Power"

As described above, the term average power refers to the average value of the instantaneous power waveform over time. As this is typically derived from the root mean square (RMS) of the sine wave voltage,[6] it is often referred to as "RMS power" or "watts RMS", but this is incorrect: it is not the RMS value of the power waveform (which would be a larger, but meaningless, number).[7][8][9][10] (The erroneous term "watts RMS" is actually used in CE regulations.[11]) This is also referred to as the nominal value, there being a regulatory requirement to use it.

Al, leave it (he is not going to get it). . 

@kijanki  Feedback lowers output impedance. You cannot make exact doubling of the power if DF=10.

Of course feedback lowers output impedance. However that has nothing do to with output power at clipping. Its not like there is some resistor in there.

I assume you are adjusting the input level as you explore these power output levels. 

What is this EXACT doubling of power all about.. Why does it have to be exact? 

I think, we are talking about two different things.  I have never mentioned actual amplifier's power at clipping but rather manufacturer's specifications (that are quite different), that calls for power doubling (or close to it). 

I have also noticed personal comments from you, placing my math ability in question and calling me to learn basic electronics.  I believe that I have some comprehension of basic electronics designing it for 40 years and therefore I view your comments as harmful, therefore refusing to comment on anything you have to say from this point on.  Perhaps one day, when you change your attitude we can start talking again.
