Default EV Interface 1 series II restoration

Hi everyone,

I old have pair of EV interface 1 series II's that my father has given me. These had been in my fatherís system for since before I was born (84) and have had a lot of use.

The tweeters have both lost their foam, the cabinets vinyl covering is peeling and one of the woofers is sounding scratchy.

The woofers have both been refoamed at some point already.

I am looking at covering the speakers in new veneer, adding new ferro fluid to the tweeters and replacing the foam lenses. I may also add some additional bracing to the cabinets.

My biggest concern is the scratchy woofer, I have removed it from the cabinet and the cones and spider seem to be intact. I gently pressed on the cone and there is some uneven resistance, I suspect the coil damaged and rubbing in the gap. Is there any way to repair this or will I have to replace the woofer?

I have attached a few pictures of the speakers.

Woud it be worth while replacing the tweeter diaphrams?

I have been looking into grabbing these foam lens parts:

Speaker Exchange | Electro Voice Tweeter Foam Lens
Speaker Exchange | Electro Voice Tweeter Foam

Will these be an appropriate woofer replacement?

Speaker Exchange | Electro Voice 8″ MS802 Speaker

The EVs are quite nice speakers! I restored a pair around two years ago and they sounded very nice.

Regarding the tweeter foam lenses, definitely replace them if you like the overall sound of the speakers. I'd be inclined to get the speakers in 100% working order first, and if you like the sound, then spend the money on crossover upgrades and replacing the woofer foams
