Of course it IS easier to reproduce 20Hz. in a small room than in a large room (because there could be +9 to +12dB of cabin gain at 20 Hz. in a small room) ... but my example of driving two 87dB efficiency 4 ohm subwoofer drivers with a $150 Sony Receiver (4 ohm speakers not recommended for that receiver) in an 800 square foot room with the ceiling peaking at 12 feet was a "worst case example" of buying a cheap amplifier and ignoring the owner's manual ... yet the receiver never got hot enough to become "untouchable" or shut down, even with bass-heavy rap music.If many speakers were "difficult loads", then we would hear hundreds of anecdotes about overheated amplifiers, amplifiers shutting down and damaged amplifiers ... but we rarely hear these anecdotes unless someone connects two pairs of speakers to their amp and plays both at the same time.
I doubt if even 1% of all speakers available would cause problems for a cheap Sony receiver, much less a much better amplifier typically used by audiophiles. I wrote 1% to be conservative.
