quoting
"Commercial loudspeakers generally have a force function containing both square and cubic terms,the second harmonic being predominant at medium levels,and the third harmonic increasing with increasing amplitude.."
-Loudspeaker and headphone handbook - John Borwick.

I think the push pull arrangement will sound pretty good

Question-when the loudspeaker is used ABOVE resonance,what are the distortion factors - is it only BL nonlinearity? definately below Fs the stiffness is providing linearity.

Book Also shows flux distribution with flush/extended pole piece(above top plate) showing reduced 2nd harmoncis by ~10db with extended pole piece

The book also goes into
-Cone modes,w
-what the concentric corrugations on cones are for,
-nodal circle overtones(non harmonic!)
-also some boring derivation of point source/flat piston at the beginning :P
-HUGE! section on electrostatics
-Sizable section on room acoustics,
-enclosures and baffle resonance measurement,
-measurements and evaluation,
-hardly anything on horns though!

I would buy this if it was cheap enough. Also 'high performance loudspeakers by martin colloms' is pretty good. SOme derivations,its abit more balanced, ie : normal amount of info on electrostatics :P

Problem is that online descriptions of books tend to hardly even tell you chapter titles! ridiculous!Im thinking of Aes anthology on CD or something...
