    708G-1 Correct Foam?

    I've got three to play with, all have torn rubber surrounds with a very narrow outer lip, all of the ebay foams are 8" "one size fits all" except one from The Netherlands that looks like a winner...but it's in The Netherlands. Is there a stateside source for the correct surrounds?


    Thinking of how I'd do the refoam gives me a headache, inside/under first would have to be spot-on or the little lip wouldn't marry up squarely. Outer lip first and then try to flip the foam under the cone without damage sounds fun as well.

    Any wisdom?

    Thanks,

    They're going into Decade 16 boxes with 035tia tweeters and an undetermined crossover. I hate to throw out good furniture.

    I looked at the auctions, $30.00 with shipping seems very reasonable for the right parts, so just get them. And let us know how they fit.

    Edit:
    Ordered, I'll report back in a couple of weeks.

    Vested interest since I have two pairs of L7s, two pairs of L5s, and one pair of L3s. That's ten 708G-1s, none of which have failed yet!

    I could only find foam, no rubber.

    M L1's have been with me almost forever, and there they'll stay. Last speaker standing.

    RBH Sound has 40+ years experience with JBL Woofers

    I’ve had six 708g woofers done by a guy that RBH has doing repairs. It took him a fair bit of research and futzing, but he can get a foam on cleanly that allows for the proper cone travel. It’s tougher to do with the trimming of existing JBL replacements and glueing both the cone and frame at the same time while maintaining perfect alignment. They charge a bit more but the work is the best in the business. I’ve had 14 jbl woofers done by them. First rate. Name:  D3632D92-E65D-452A-A2E9-EAB8846644DE.jpg
