Default Mission 700 Woofer Replacements

Trying to source replacement woofers, as the pic shows the orig was made by Siare model number SPCG3D.

My old man has already tried years ago of taping splits up etc with predictably bad results but say no more.

Tried to contact Mission but the webform doesn't send so Ill try again later. Also contacted ampaholics to see what they have.

I don't necessarily want an exact replacement if something cheaper/readily available will do the trick.

Many thanks for any assistance here, Happy New Year.

I have that exact same model and my foam rotted out about 5 or 10 years ago. my spkr system was bought new in 1982 or around that time. got lots of years from it and it was my favorite spkr for its size/price.

I also need a refoam or new woofer.

(or, if anyone wants my cabinets and tweeters, I'm open to let them go cheap)

Thanks but it's the driver that's broken not just the surround unfortunately.

I'm tempted to try and salvage the cabinets and ditch the crossover and see if a full range driver will work, but bow to the forums better judgement first.

If not I'll have a look for a replacement woofer.

Cabinet dims are:

Internal Vol = 11.9 litre (19.5 litre without foam)
External Size = 460 x 260 x 243 (38.5" x 21.7" x 20.25")
Port = 56mm dia wide and 95mm deep, placed 109mm from base edge to its centre point, and 51mm from left hand outer edge to its left hand edge.

I can fill in the woofer and tweeter holes to suit.

Or I can scrap the lot.

Thanks for any advice
Nathan

That link is perfect thanks!

I was also looking at adapting the cabinet for some Fostex FF165K as they are higher sensitivity and not too much dearer that the Monacor SPH 210.

thanks again, Im new to speaker building and hate to see old items left ruined really but at over 80 to repair i could prob buy some from ebay and re foam theirs.

converting to full range drives would work perhaps?

Surely the "Fostex box" wooden cabinets from Moldova (on Ebay) are worth the money?

fostex box | eBay

The shipping is a pain mind.

Default Replacement woofers for Mission 700s

A few years ago I replaced the woofers on my Mission 700s with Peerless, catalogue number 832737 woofers. A good fit and to my ears sound very good, though, as a bit of a purist I now regret throwing away the originals (the foam surrounds had completely disintegrated) - didn't know that the foam surrounds could be replaced. Good luck.
