Default Mission 737r restoration... need help

Hi, I bought a pair of Mission 737r without original transducer. I am (almost) sure that mine is second version cause grey baffle (serial is 317747). I would know if somebody could tell me brand/model of tweeter and woofer that originally fitted this speakers. In attachments some picture. Please help.

Thank you

Elio

Hi,

Click the image to open in full size.

Bespoke unobtainium 8" polypropylene bass/mid (probably made
by Seas) and a badged Seas or Vifa 3/4" soft dome tweeter.

rgds, sreten.

Thank you for your reply. Do you know which other Mission speakers used that tweeter/woofer? This could help me to find something used on web.

Regards

Elio

Hi, since I have not original woofer, I can just measure the place where transducer is housed. This is about 21,2 cm. I spent this sunday afternoon searching on the web for further information. I am pretty sure that Mission770 uses same mid/bass unit and, probably, the same tweeter. Somewhere I read that a good replacement for Mission 770 woofer is Vifa P21W0-20. Concerning hf unit, you're right because tweeter was produced by Vifa. There are some offered on the web, similar by shape but I don't know by specifications. However, all of these tweeters seem derive from the line of Vifa D19 (a Mission replacement sould be R 761-HFU-D19). I am still working to understand more. I will contact Mission Electronics for information but I can't now because Mission website work well just in Windows & I.E.! I am a Linux user...

Thank for you kind help

Elio

Hi, thank you for your information. I think that H225 Seas fitted first version of Mission 737r. Are you so kind to tell me something about brand / model of 8'' polypropylene woofer (...probably the same of Mission 770)? It's really strange, but contact form on Mission Electronics website doesn't work with any O.S.!!! Really crazy!
