Meyer Sound MS1401A

[Emmanuel Von Deus]

Hi guys, 

I am looking for a while for a replacement diaphragm for my Meyer Sound MS-1401A without success. I have no specs on, nobody seems to give details, especially Meyer service!!!

Please let me know if you know anything that can help. I consider buying a pair of Yamaha  6681B. 

Any help is welcome!!!

Thank you in advance
