Next stage of my curbside acquisition thread.
Would you order new foam for this and give it a go? Tweeter and mid range sound OK. The woofer had dry rotted foam. Think it's worth $30 bucks or so to refoam? Kinda rattles when I send music it's way. I removed all the foam I could.

Called Parts Express this am to inquire about a foam kit, which costs about $27. They wanted $10 FedEx shipping for a kit that can't weigh a pound including a box! Wow.....I'm looking for alternatives.Husband, Father, Son, Brother, Friend.

wooferrepair.com is much more reasonable...a $22.50 kit + $5 shipping.
Should this have been in the DIY section?Husband, Father, Son, Brother, Friend. -
I have always used Parts Express re-foam kits, except for one time when I re-foamed some Advent woofers. To me, the PE kits are a decent value. For 10" speakers or less, you get two different kinds of foam (different profiles for the flange that glues to the cone), two different kinds of dust covers, all the voice coil shims you need, the correct glue, glue swab applicators, and detailed instructions with photographs. I think 12" and 15" kits only come with one set of foam, but I've never re-foamed speakers in that size. The shipping has never seemed onerous, maybe because I have never ordered just the foam kit when I placed the order, and always use the cheapest shipping option. I'm not shilling for PE, other vendors offer similar kits I'm sure.
Furthermore, you're going to need to get ALL of the foam and old glue off that cone. Based on the photo, you have a ways to go. You're going to need to scrape the foam and glue off the cone with an X-acto knife or a razor blade or something. Also, the gasket around the top of the basket (looks like it may be plastic on your speakers) will need to come off, and you'll have to clean the gasket and the basket of all the foam and old glue. If the gasket really is plastic, you ought to be able to use Goo-Gone on it and the basket to clean off all the old glue, but I wouldn't try it on that paper cone. You want to replicate as much as possible the original condition of the parts when they were originally assembled.
Finally, it's no surprise that the woofer rattles when you try to play it in this condition. There's nothing keeping the voice coil aligned. If the rest of the speaker is in great condition and you like them, I'd go for it. Once you've resurrected a pair of speakers, you'll be off to the races. -
I've never refoamed before, but it looks to me that there's still a bunch left on the woofer that will need to come off to get the new foam to adhere properly.

Re the remaining foam - noted gentlemen. I never intended to continue as-is. My pics were only informational at this stage.Husband, Father, Son, Brother, Friend.
