Mission 700 Speaker rebuild - phase I

My brother has had these for a few years and the foam around the woofers is gone. So we're taking the opportunity to do a rebuild of the woofers and crossovers.

These boxes are a bit unique in that the woofer sits on top and the port is below the tweeter. The speakers are also fixed in the back of the front panel with brackets and the grill is not removeable.

Woofers went off to MillerSound for Bill to do his magic on them. They came back perfect as was expected.

Tweets are probably Seas?

The crossover components were removed completely.

and replaced with some better components.

Phase two will involve some inner bracing and a new back panel but for this round I'm reusing existing parts as needed. Since the port is in the middle of the bottom I split the crossover components. Woofer on left and tweeter on right.

Placed the damping back in again and off we go.

They sound very nice!

    Sweet!

    Are those 700s or 70s? I've never heard of 700s, and they look like 70s, but I'm not an expert on Missions. edit: After a brief Google, 700s are very much a thing. :)

    All the Mission speakers I've seen (Relatively few) used Vifa drivers. They could have also used Seas, but I've only seen Vifa. And the mid over tweeter started to become a trend for Mission during this era. They still do that to this day.

    You got yourself a great set of speakers, as you already know! Happy listening! :)

    I've always thought the goal of high-end audio was not to have your neighbors bang on the wall and say, 'Turn that darn music down' but to have your neighbors bang on the wall and say, 'Tell your friends to go home and you can practice later this week'.

    Nice rebuild. What is the 2way with the Scan Speak drivers? DIY?

    The badge was still attached and said 700's. I still can't find a picture of these things. Might be an odd short run or possibly mis-badged?

    Those...those are my babies!! They are Odyssey Audio Lorelei's but soon to be replaced by their big brothers, the Liquids. If all goes well I'll be heading to Indy to pick them up in a couple of weeks.

    Ah Ok. A Scan tweeter and woofer are usually a recipe for a very musical 2way.

    No, I think that is correct. Like I said in the previous post edit, I googled it and it came up with pictures of what I would have labeled 70s. AFAIK, all Their speakers had to be bought in Britain and shipped across the pond (as far as I know that was the case for all their speakers at the time, but I'm not sure. None of their new stuff can be bought from America) but maybe the 700s are a US equivalent to the 70s? Who knows. Maybe the Mission production line was akin to the early Polk line... ;)

    Maybe I'll do a bit of research on that issue tomorrow. :)

    Some early Missions were built in Toronto Canada. Not sure which model(s).

    Nice Work! Don't you just love restoring something back into original or better condition?

    Phase II

    Vertical is offset so it clears the port.

    Damping back in place.
