Speaker surround replacement - any recommended or not-recommended suppliers?

    I've got a few pairs of speakers I need to replace the foam
    surround on. I have found a bunch of places with widely
    different prices for the foam surrounds. Does anyone here have
    experience with these or others. I am curious about the
    quality/durability of their products. Are the expensive
    ones worth the price difference?

    Some places sell the surrounds only with angled or only with flat inside edges.
    Does the angle make any real difference?

    Last question first: the angle makes a difference. If your driver has a
    an angle, you need to match it. If it has a flat rim, you need to match

    As far as the different products go, if you need a kit, with glue,
    shims, instructions and dust cap; go with one of the brand-specific full
    kits offered. I doubt you'll get better components than if you buy from
    the company which sells bulk surround rings, but I can't say for sure.

    I went that way myself the first time I did a refoam; but I've still got
    plenty of glue left from that job. Shims are merely pieces of paper or
    cardboard; and the dustcap can often be reused. So, if I were doing it
    again, I'd probably just buy a pair of surrounds and go at it.

    Also, beware of woofers you acquire in deteriorated condition. If you
    know the history of the driver, and you are sure they have not been
    played since the surrounds rotted; you have a pretty good chance of
    resurrecting them. If not, your chances are less than 100%. There are
    many bad things that can happen to a driver if it has been used with a
    bad surround...all of which are fatal (another reason to do it as
    cheaply as possible).

    Also be aware that the driver may not sound 'exactly' as new. It's
    almost a sure bet that the compliance of the replacement (unless--or
    even 'if'--sourced from the OEM) will not match the original. It's left
    to you to determine if that's an issue or not. Given the wide variance
    in driver compliance--and the small contribution of that parameter to
    the overall sound--I tend to discount it. However, the process should
    always be done in pairs...never fix only one of two. Even if the other
    'looks' okay it will need to be done, sooner than later (especially
    keeping in mind that bad things happen to otherwise good woofers, when
    the surround deteriorates in use).

  3. Orange County Speaker Repair (speakerrepair.com) does good work with
    fast turnaround time. I've had at least half a dozen speakers of
    varying brands and sizes rebuilt by them in the past 2-3 years (I
    handle the maintenance for a club where the PA takes a hell of a
    beating, 7 nights a week). I've been very happy with their service.

    What kind of speakers are they and how is the surround attached?

    If it is at all possible to use a refoam kit from the manufacturer, do so.
    Otherwise the Waldom kits are pretty good for most speakers althout not for

    Some of the Parts Express kits seem to be good and others seem to be crap and
    you don't know until they arrive which they are.
    It depends on the drivers you're working on. Your goal is to have the same
    stiffness and same X-max as before, and to have the resistance linear across
    the whole travel. The good news is that the surround really affects the
    suspension stiffness less than you'd expect, but you can move the Fs around
    a little if you don't use the right replacement.

    First to try AR18B's
    Second Speakerlab 7's
    Third Dahlquist DQ12's

    They are all glued. Foam to paper.
    The only Waldom I find is a "distributer's distributer" - I can't find a catalog
    on their site.
    What is the difference? What do I need to look for or watch out for?

    AR should have kits available. I'd ask Dahlquest also if they have
    The catalogue costs money to get. Image Communication can sell you most
    Waldom items, or they can set you up with a recone shop that might be
    willing to sell you parts.
    The differences is that some fit well and some don't fit well, some are
    very poorly made with a lot of flash around the edges, and some of them
    match the compliance of the original and some do not. You order them
    and then you see what shows up. Sometimes some cut and paste work is in

    Dahlquist is long gone, as far as I can tell.
    I can't find "Image Communication" either
    Thanks for that info.
