Default Mission 770 Driver Replacement

It seems I have blown the woofers on my pair of Mission 770's. Both of them measure open circuit. Does anyone have any information on suitable replacements? They are 8" drivers manufactured by Seas. The marking on the back of the driver reads (I think) 21 F-P/DD. The outer flange diameter is 21.5 cm. Seas doesn't seem to make anything similar anymore.

Any help would be appreciated, these were great speakers and I'd like to get them going again.

Mission might hold spares...
I got some 700 foam surrounds from them. You may be able to get replacement coils or cones and refoam to fix.

From their FAQ -

Can I still purchase replacement parts for my Mission speakers even though they are out of warranty?

Yes. Mission endeavours to carry a comprehensive range of replacement parts for many years covering both current and discontinued models. Typically, these will include spares items such as tweeters, woofers, grilles, plinths and foot spike sets. Please contact our service desk on +44 (0)1480 452561 or e-mail to spares@mission.co.uk for prices and availability.
