Ah! Well, as long as the driver frame is in the exact same position as on the original baffle there should be no issues there. This should be the case with my part but I will double check tomorrow.
Had a bit of listening time with it today and I was enjoying it but I am definitely getting a high frequency peak there (which seems to be characteristic of the stock T50RP too) that I would love to get rid of.
I am trying to see how much I can change the sound of the T50RP using fully consistent and reversible 3D printed parts.
Aside from trying various materials, internally and ear side, I wonder if the cup and baffle design can be changed to reduce the 10 kHz peak? For example, what effects may result from altering the cup shape, cup depth (and increasing the height of the shock absorber posts to compensate for greater cup depth), changing the cup floor topography, adding cup floor and baffle diffusers, etc.?
