    Reconing subs, got spyder glued down. Now surround has a 1/2" gap. how to fix??

    I bought a recone from member on here. Got the spider glued down now the sub needs to be pushed down and held down to glue the surround. I thought it was supposed to fit

    Pics?

    Sounds like the depth of the cone is wrong and you're going to compress the spider to get the surround to sit on the lip of the frame? The suspension will not operate correctly if that's the case.

    I had to push it down 1/4" the guy who I bought em from said it would be nbd. It looks normal I guess.. What will happen if the suspension isn't right?

    so now that the surround is glued down is the spider sitting flat or pushed in 1/4"?

    it is perfectly ok how that sits, it will NOT compress the spiders,lol.

    i dont normally stock 4 spoke baskets in 15" so had to do the measurment and thats fine.

    look in the pix where spiders are clamped the surrond is only up bout .200" tops.

    like everything i do your totally covered.

    havent i answered all the texts questions you have had?

    post a pix of when glued up

    Re: Reconing subs, got spyder glued down. Now surround has a 1/2" gap. how to fix??

    Spiders and surrounds exhibit restoring force in both directions as long as they are moved out of rest position. You're saying it's okay to bias one or both of them and there won't be any penalty? Fact is, since the cone is biased upwards and the spider is biased downward (even if it's 'only' a 1/2"), once that's glued you've given up exactly that amount of travel from both the surround and the spider. Next we can talk about the Klippel curves that would reveal the god-awful behavior that situation causes.

    Guess it doesn't matter if it's going to get thrown in a vented box with too much port area and hammered on at 50Hz.

    BTW, I'm not trying to beat you up, sorry to come at you like that. I know you do good work. Just wanted to touch on this point of biasing a suspension.

    Re: Reconing subs, got spyder glued down. Now surround has a 1/2" gap. how to fix??

    there is only 3/16" dif once the spider is glued down not a 1/2".
    it wont push the spiders down at all and the surrond and spiders will allow more travel than the basket will allow.
    look in pix with spiders glued down.
    it dosent take any roll out of the surrond gluing like this.

    i enjoying talking subwoofers, for people that are up on reconing with kits i recomend them sending in. i ONLY charge $25-30 to build a woofer up and use all my glue and give a 90 day warrenty.

    Re: Reconing subs, got spyder glued down. Now surround has a 1/2" gap. how to fix??

    i gotta agree with SPL, if the foam has more travel then the basket and or spider will allow then a little offset won't hurt at all, and might help stability by adding a little preload to the suspension. (like in a car, kinda) i don't build speakers but i do work on them locally. (mostly JL's because all the kids here hear JL and promptly wet themselves) SPL has even helped me out with advice and he tried getting me parts for an oddball ancient speaker with a stamped steel frame that i was working on, he is definitely a good guy to work with.
