Sounds like you have line level output jacks for Zone 2 on your AVR, which is very common. That means you need to supply an external amplifier.
I've posted that information on AVS a goodly number of times. Where were you?I've posted that information on AVS a goodly number of times. Where were you?There were no actual transducers, just electrical networks that had similar impedance and nonlinear load properties.There are at least two problems with using transducers for tests like the one above, that involved operating at high powers for extended periods of time:(1) Loud to the point of being painful(2) Speakers...
+1.I daresay that the good doctor is on his way to claiming that there is no such thing as the threshold of hearing, and that we can hear anything. ;-)I will now challenge him to tell me the words of the book that I am reading aloud, no matter how far he is away from me...

the above is false. I have provided experimental evidence that contradicts it, but to no avail:As i just explained in another post, the above is exactly wrong. Reactive (inductance and capacitance) loads dissipate less of the power delivered to them than resistive loads with the same impedance. Part of the energy delivered to them though part of the output cycle is returned later on.
"Muffin" and "Whisper" are trademarks of the Rotron company that is still in business as Ametek Rotron..Here is their full catalog of those fans:http://www.rotron.com/download.asbx?AttributeFileId=d541ecb8-05aa-4d90-b6d8-ac7f5f6eededif you download that catalog you will find that the quietest of them is speced to have noise of and I quote: "Acoustic levels as low as 36 dBA"Modern 120 mm fans have noise levels below 10 dBA.
Any reasonably good teacher or authority in the area of experimental design or statistics would say that due to all of the serious uncontrolled parameters no audiophile amplifier listening test is valid.Try me - call up the head of the statistics department at any nearby university and explain how you test amplifiers!As was said above, obviously an invalid test can not prove or disprove ANYTHING.Why then are audiophile amplifier listening tests given any credibility by...
The usual convention is to rate a speaker's impedance at a bit higher than its actual lowest impedance, which is usually reached over only a small portion of its impedance curve. Therefore the speakers average impedance usually runs about 20-50% higher than its rated impedance.Speakers present a reactive load over much of their frequency range. A reactive load does not dissipate all of the energy thst is delivered to it like a resistor, part of the energy is returned to...
