Mission 707 crossover rebuild.

[jason young]

This is my first post, I'm fairly new to the hobby and am wanting to rebuild a set of mission 707 speakers. Picked them up for $10, they need foam on both woofers and I'd like to rebuild the crossovers. Figured this would be a good speaker to start with. Where do I start?

I'd measure the inner and outer diameter of the surrounds, and email the measurements to midwest speakers to get some replacement surrounds. As for crossovers, I usually only replace electrolytic caps. Read the values off them, you can go higher on the voltage. If I can't find exact capacitance, then I run two capacitors in parallel that add up to original value.

I used a model '8-inch JBL Thick foam edge' replacement surround on my mission 707, as most other foam surround fit over the speaker cone rather under it . but need to trim off abit of the outer diameter.

Outer diameter(red line):205mm

Inner bubble(blue line):162mm

Hi Jason. Where did you get your capacitor from and which brand did you use on your 707 and what value?

That's good to know, since I am always on the look out for Mission speakers. I used a JBL 8" surround when I did a pair of AR94S.
