Sub output: Is it the woofer size or the rated RMS


In any subwoofer output, how important is the Watt output versus the woofer size? I have been reading reviews on some subs such as Earthquake, Sunfire and JL audio. The Earthquakes (15" woofers; ~650W) have reportedly more "slam" than the Sunfire (1000W-1500W, 12" woofer), or the 650W-750W SVS, or even the fathoms.
And each of these are box subs.
Or is it really about the proprietary technology unique to every sub?
In other words, what really influences a sub's output for all the wonderful things we want in a great sub?

There are many things I could say to socalled sogood but will stop with saying that I have been in audio 46 years, some of it as a Krell dealer, have 4 pairs of subs, none of which I would trade for any of his, and will end with what my wife told me to tell him, " its not the size of what you have but what you do with it."
I just thought Stanwal's " cone linearity " statement was complete hogwash, and implying some advantage, towards smaller drivers.

Truth is, from 20-80hz (normal subwoofer range)...small drivers have no advantage over larger drivers.... at reproducing these very low freq's

Just trying to stop the spread of internet B.S. from taking over.

Sorry for being "insulting" in my approach....my bad...over and out.

Its not your insults I mind ; its your stupidity. You obviously have no idea what you are talking about. I suppose you never heard of "speed" in a sub woofer. If all you are interested in is making noise then the HT set up you seem to favor is fine. For those interested in serious music reproduction other considerations come into play. Oddly enough, my motivation is exactly what you profess yours to be, the prevent the clueless from misleading the unwary. My two REL Stadium subs use one 10" Volt driver each and cost $3000 each. I suppose that is your idea of cheap. You appear to be one of those who thinks that because they have spent a considerable amount of money on their system they have some how acquired knowledge and authority. Making wild and unsupported statements is hardly the mark of knowledge.
I for one believe that a fast sub is not reproducing deep bass. The very thing that makes deep bass deep is the long wavelength. I am not saying a small sub can't make deep bass. It just takes much more power and further cone movement than a large sub. The further cone movement negates the quickness of the small sub because a small sub must move in and out so much further than a large woofer, it is just as slow.
