The 37-9 uses an H-30 speaker.

Field coil DC resistance should be 480 ohms; voice coil impedance 1.25 ohms.

You can find complete specifications of this and other 1929-1938 Philco speakers here:

When you go to that link, look for the link to the file speakers.zip. This is an Excel 97-2003 file (*.xls format) which can also be opened by newer versions of Excel as well as by OpenOffice.
