Home High Efficiency Speaker Asylum

Need speakers that can rock with just one watt? You found da place.

RE: Large Cones = More Realistic Lower-Mids Tone?

"To prove this 'surface-area' theory, double-stack two pairs of mini-monitors, and see if the double-stacked pair doesn't reproduce music with slightly more realistic 'body', apparent detail, and 'substance', in the lower-mids, than the identical single-pair, as one magazine's writer recently discovered. (Refer to The Audio Critique)."

No surprise there, a pair of speakers driven with the same voltage as a single provide 6 dB more output, 10 dB sounds twice as loud to our ears at 1000 Hz. Using two speakers the excursion is only 1/4 a single needs to achieve the same SPL.
A given low distortion SPL may be reached with multiple small cones or a single cone equaling the same cone area if both speaker types have the same Xmax.

Most commercial offerings use small cones because most consumers want a small cabinet, and are not very interested in huge dynamics.

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.

If one desires low distortion front row orchestral, big band, or rock concert levels, a 4" front loaded cone at two or three meters distant will obviously not be up to the task.

For average listening levels, the same cone may be more than adequate.
