Hello everyone,
I would like your opinion on the sound of a membrane of the midrange
eg polypropylene against the paper treated ...
Polypropylene: HDS-P830870 http://www.tymphany.com/files/HDS-P830870 Rev 2_0_0.pdf
Treated paper: SB12MNRX25-4 SB Acoustics :: 4" SB12MNRX25-4
SB12MNRX25-4 the treated paper is tough
the HDS-P830870 is made of polypropylene
all with a cone stiff enough, what are your opinions on the sound of these two speakers?
What do you think of the sound of the midrange sbacoustic treated paper?
and polypropylene peerless?
someone says that the paper sounds better and colored polypropylene
should be intresting a comparison between both

The geometry and material that the cone is made of will affect the frequency response, particularly the shape of breakup nodes. It will also shape the harmonic distortion produced by the motor accordingly - i.e. if the cone rings like a bell at 10KHz, expect bad 3rd order harmonic distortion at 3.33KHz.
For someone to say that all poly cones sound like plastic, all metal cones sound like a bell or someone hitting and tin can and all paper cones sound like... whatever paper cones sound like... would be naive. There is much more to the sound of a speaker than just the cone material.
In the case of the two above drivers, they both have reasonably controlled breakup, and power response is similar. Therefore the breakup nodes probably aren't going to shape the harmonic distortion drastically. If you use them within their optimal bandwidth (say, up to 3-4KHz) the difference in sound is going to come from very minor differences in frequency response and the distortion produced by their motors.
