Parts Express Diaphragm for Old Version 4"x10" Midrange Horn or Similar Heppner/Foster-type Drivers
I have a pair of older Sonic d12 12" monitors and need to replace the horn diaphragms. These look the same. Do you know if they will work?
There is no way to know whether these will work for that specific application or not. We have a 45 day hassle free return policy, so if you tried them and they didn't work you could send them back for a refund assuming they are undamaged and are in the original packaging.

What is the difference between this diaphragm and the Selenium RPDT150?
While these look similar, the tolerances and overall dimensions will be slightly different since they are designed for two different drivers.

Is the "voice coil flange" measurement overall diameter or voice coil diameter?
I am looking to replace diaphragms with 1" voice coil diameter, and I have seen other replacements differentiate between "voice coil" and "diameter" measurements, e.g. 1" voice coil, 1 3/4" diameter. Just need a little clarification. Thanks!
The voice coil diameter on this diaphragm is 1", overall flange diameter is roughly 1-3/4".

Is this a replacement for the Foster/Fostex type diaphragm?
I have heard of customers using this diaphragm with Foster/Fostex drivers, but I have not verified this to be true.
