   In my experience the manufacturers are simply trying to reduce the number of   
   warranty repairs to some extent by specifying the higher resistance. In   
   truth, with a bit of common sense applied at the volume control side of the   
   equation, a four-ohm speaker will work just fine with any solid state amp or   
   surround receiver of even minimal quality, such as Pioneer, Sony, Marantz,   
   Denon, Kenwood, etc PROVIDED as I say, some common sense is used and the   
   user isn't trying to use the thing as a sort of mini-PA system.   
      
   Problem is, people connect all sorts of speakers, even for example car   
   stereo speakers wired in unusual, often incompetent ways, then expect to be   
   able to blast away for hours on end.   
      
   Yamaha, for example, knows full well that one of their power transformers   
   will not have a failed thermal fuse in the power transformer in the absence   
   of customer abuse - playing the thing at a very high level, probably with   
   low impedance speakers (or combinations of speakers) for an hour or two more   
   or less continuous.   
      
   Therefore, they will only cover ONE power transformer under warranty. The   
   warranty servicer is expected to educate the customer that a second   
   transformer won't be covered.   
      
   In fact, the newest Yamaha's will "rat out" the user by recording how high   
   the volume was for more than one minute and how many times. This info is   
   accessible in the service menu.
