Looking for foam surrounds for SD 300ti

Sound Dynamics 300ti. Midrange foam has disintegrated. Can't seem to find right size:

Frame od: 5"
frame id 4"
OD of speaker cone.....3 1/4"
flat edge for gluing surround to speaker 1/8:

Why do people refer to these as 4.5" speakers???

Hi,
I also need foam surrounds for my 300Ti mids. I measured the surrounds while still attached to to the basket and cone, with a dial caliper, and the O.D is 4.5" and I.D is 2.875". That will allow a 3/16 overlap on the cone if the cone O.D. is 3 1/4" Does that seem right?

Thanks,
henrylr
