    Charles, I don't think many folk who have old speakers expect them to sound as original factory spec!!!

    True Oli, everything changes in the audio chain, some for good and some bad. Most equipment needs to run in and will change slightly over the course of its life. Caps deteriorate as do stylus. So what, you live with those changes if they still sound good or you replace.

    Not sure why Charles has got his knickers in a twist about "original factory spec". I expect many folk have speakers or equipped that has drifted from factory spec, especially if it's old.

    Speakers are made with tolerance, the same as everything else mate. If a Capacitor or resistor is out of tolerance, we change it bur thats Not easy when you're using speakers from 1971!!! (mine) also, where are the specs for tolerance of rubber surrounds movement and vibration resistance and how is it measured!!! What a load of bollocks. Obviously, if there is sag or a bulge under the weight of a driver then sure, that'd need changing but come on!!!! I've NEVER seen that in a quality speaker of this calibre.

    It's incredible that such a statement has been made that "ignorance" is playing a part in your pleasure and your speakers are inferior due to their age!!!

    Ridiculous.

    Enjoy your speakers mate. I really did.

    I don't believe that the type of rubber used will harden over time.
    In my experience when rubber hardens it takes on a matt looking surface and eventually starts to show fine surface cracks.

    I also was under the impression that a woofers resonant frequency drops as it gets older due to lower stiffness, though this may be in the spider primarily.

    I cannot remember the surrounds from seeing them in about '93, but I think they are similar to my own on LS 5/8 mid/woofers which are a PVC based plastic, though I have seen it described as neoprene. It is not particularly springy, less so than rubber, and has more damping.

    This material was chosen for its longevity and stability, foam being the worst these respects.

    Alan is right about rubber.

    Just a bit annoying when someone makes statements in such a condescending manner. A good proportion of us folk here on AOS use old speakers and a aware of the possible changes in their structure due to their age but unless they sound terrible or even affect the sound audibly to a negative degree, we live with them.

    One of the reasons I still use the original SP2 is because on later models they changed the cone material and specification and they did not sound as good. Maybe it was down to cheaper production techniques or cost cutting but to my ears the SP2/2 and SP2/3 don't sound as good.

    So what does that say, buy new in spec speakers that sound inferior or live with old out of spec speakers that sound great!

    Old speakers Don't need to have gone backwards at all. Mine are about as old as me and sound terrific. Wish I had fared as well

    I wonder why so many of us have "old, out of spec" speakers? Must be because we're deaf

    Speakers are generally regarded as having a 'break-in' period.

    Surely once break-in has occured, the speakers are no longer at their 'as new' manufacturer's spec? The cones having established break-up patterns within their material structure and the suspension gaining greater compliance. So would the post 'break-in' spec be the aimed for and correct spec?

    A comparison would be interesting. New speakers measured straight out of the box, then similar speakers tested after say six months of hard use.
