So, by flatter you don't mean pitch?  You mean duller?

Yes. I also found that true of a few Gilberts and Konos I've played.

Interesting, when did Ramirez start making double tops.  Also, I'm
curious, are they the same string length?

Same string length. Mine is an '84. By double top I mean a second
"top" half way between the back. You can't see it unless you look
inside and it goes all around the inside about 4 inches from the
sides.

"In his De Camera guitar José dealt with the problem of the
elimination of the so-called "wolf notes", characteristic of all
wooden stringed instruments. These notes, which are almost always on
frequently-used pitches, have a weaker and more smothered response
than the others. The better the instrument is, so much more are these
tones evident. Their cause is found in the irregular pattern of the
wood, where we can find knots and other zones that resist vibration.
Attempts to minimize their existence have usually resulted in the
frustrating "revenge of the wolf notes," wherein after a certain
period of time they reappear even more evident than before, due to the
vibratory stress on the "corrected" wood. A possible solution occurred
to José after his study of the behavior of spherical sound waves and
their development. Using a little calculus and a lot more imagination,
his intuition brought him to envision a chamber placed inside the body
of the guitar that follows the internal contour of the body and is
able to minimize the problem."

I have a hard time understanding how calculus fits into Ramirez's
thinking here. He probably at one point saw a Lacote with a second
soundboard inside and his imagination went from there.

I've seen and played a De Camera. They have a rosewood
reinforcement attached to the sides that trace or follow the plantilla
about 4 inches out. The reinforcement is as though you added a second
back in the same way Lacote did but then trim the second back 4 inches
from the sides creating an opening the same shape as the guitar,
starting 4 inches in from the sides.

Smallman did the same thing with the rim he glues to the sides
inside the guitar.

I fail to see other than making the sides more rigid, which on cedar
can be quite beneficial in increasing sustain and balance, how this
has any effect on wolfe notes, which are caused by plate, and air
resonance coupling. More Spanish romantic mystical sales hype to me.
Sorry to pop your cherry Larry.
