Weltersys,

I appreciate your response. But the arguments you present really do not counter those I've posited, at all.

For instance, we all agree to what you said, here: 'No surprise there, a pair of speakers driven with the same voltage as a single provide 6 dB more output...' (i.e. if you mean; 3 + 3db, relating to power and surface-area).

But that argument does not address the point you dispute since the increase you point out is across the board, albeit centered at 1khz but, inclusive of all frequencies. It does not address my point that increasing cone-surface area results in more 'body' at lower-mids because of the fact that the increased surface-area more efficiently pushes more air thus presenting more substantial lower-mid tones (and the same applies to bass). Other frequencies are un-affected in this regard. Therefore, your argument doesn't apply.

"Using two speakers the excursion is only 1/4 a single needs to achieve the same SPL". This is another admirable argument, with which I agree but, again, it fails to counter those I've presented - for the same reasons outlined above.

"Most commercial offerings use small cones because most consumers want a small cabinet, and are not very interested in huge dynamics". Again, I agree - with the exception of the part about dynamics since, for those seeking realism, dynamics (not necessarily 'huge') is an indispensable part of the package (missing in most small-coned speakers, along with the equally indispensable lower-mids).

However, I respectfully disagree with your final point: "A recent thread in DIY audio (http://www.diyaudio.com/forums/multi-way/204857-test-how-much-voltage-power-do-your-speakers-need.html) found most of the respondents listen at average levels of 80 dB or less, even low efficiency small drivers sound just fine at those levels, which only require a few watts to achieve."

Specifically: "..even low efficiency small drivers sound just fine at those levels, which only require a few watts to achieve.". My argument was/is not about overall decibel-levels, or wattage. My argument is really about TONE. This does not address that. Indeed, non of the arguments you present addresses the points you seek to dispute, unfortunately.

Nevertheless, I sincerely thank you for your response.

Cheers.
