Default Mark Audio 7p vs. 10p

There has been a lot of discussion about these drivers. When comparing them
I can't understand why the efficiency rating is different for the two..... the curves look very much the same.

Because the 10p is bigger?

You have two different sizes here (among other things), hence why the different efficiency/sensitivity numbers.
I don't own them both, but I guess they are somewhat similar in the context of MA type of sound and performance, but very different on the other hand as they are different sizes and purpose/designed for. Bass would come to mind, slam/presence and maybe dispersion?
The curves won't tell you much, there have been euphoric threads about that and the way the data is published/measured. Take it more as another data about the driver, but not too serious.
Just my thoughts...

Because the sensitivity is usually given as an average of the SPL within a certain frequency range.

FWIW, I do happen to have both currently operating in my 5.1 system, and thanks to the Audyssey automated calibration procedure, the sensitivity difference is irrelevant.

I wonder if there is a more substantive question lurking - as in "sensitivity aside, what are your impressions when comparing the two?"

That the published graphs bear for the most part a general family resemblance probably speaks to Mark's acumen and experience. If there was only the approx 2dB difference at play, they could be expected to sound very similar - but in my experience, the over 20Hz difference in Fo, as well as other T/S parameter that I still don't understand, makes the 10P a much more versatile driver. In a full sized enclosure, such as FHXL, or a Pensil, etc, I could live with them quite happily. Well that's a bit disingenuous , as I recently upgraded to them from 7.2 &3s in the front row of modest HT system, and find the results overall more dynamic . And let's face it, the substantial audio signal processing present in surround program material might well render the smaller driver's advantage in areas of "finesse" , low level detail, DDR - whatever audiophile tweaked buzzwords you like, somewhat moot?

Or maybe that's just me
now on sabbatical
