Offer voice coil material three options,  Aluminum, Copper or Copper lite.  

 

Aluminium coil - better reproduces high frequencies.  

Copper coil - weighs more than an aluminum coil, so it works better at lower frequencies, but high frequencies are cut a little, and the sound by ear is more calm, stable.  

 

Copper lite coil - weighs like aluminum coil, frequency range is similar to an aluminum coil, but the sensitivity is 3-4 dB lower, and sound is a little better by ear (aluminum coil, have unpleasant, aluminum overtone).  

 

Any resistance up to 2500 ohms! (After surchase tell me what you need impedance and what winding).      

 

 

The paper pulp is based on long-fiber Siberian larch cellulose, which is very durable.    

Approximately 30% lighter than original metal ones.   

The frequency response and impedance characteristics are practically no different from the original ones, with the exception of a slight, smooth decline at higher frequencies.    

 

The sound is without metallic coloring, more natural and stable.  

 

If you need graphs, please write a message for which diaphragms.    

 

Price for one diaphragm, unless otherwise specified.

 

Thanks.
