...which I think most would agree, then peaks of 20dB's would refer to ranges beyond 300 RMS, in which the amps protective circuitry would be introduced.

By protective ciruitry, I am assuming you mean a shut-down circuit. Since EMO is using a waveform limiter, a shut-down circuit should not be necessary. The limiter should attenuate the gain of the amp...not shut it down. Otherwise, what exactly is the point of the limiter?


Other people with 4ohm speakers from Onix, NHT, and Axiom are having the same issues when pushed to similar levels.

I am starting to wonder if the resistors EMO used to simulate speakers during power testing changed value as they were being heated. The devil's in the details.

I find statements such as these on the EMO site worthy of further inquiry. I very much doubt EMO is achieving 0.015% THD into 4 and 2 Ohms:

• THD less than .015%, 20Hz-20kHz with 80kHz measurement bandwidth
• 200 watts/8 ohms – 300 watts/4 ohms – 400 watts/2 ohms - seven channels driven, mains limited
• Frequency response 20Hz-20kHz +/- 0.1 dB, or 10Hz-125Khz +/- 3dB

A spec written like this would certainly be less confusing (some of my numbers are made up): Frequency response 20 Hz to 20 KHz +/- 0.1 dB with 0.15% THD for 200W into 8 Ohms, 1% THD for 300W into 4 Ohms, 5% THD for 400W into 2 Ohms.

Having said all of this, for the price, I would certainly be happy with one of these amps .
