    A classic JBL S7R system in them. The bass will be restored by changing the surrounds or with DOT3.

    Just to be clear on what is generally understood the DOT 3 treatement is applicable to the yellow Lansaloy surround, only. Yes?

    Yes, the old Lans-a-loy material gets stiff and brittle over time. Any of these older woofers from the '60s were already stiff by the '70s and that is when JBL switched to the gray urethane foam that turns to dust instead.

    If you own any older JBL woofer with the yellowish surround material do some searches and you'll find tips about using the DOT3 treatment as well as good arguments against using it. Regardless of whether or not you decide to use the brake fluid treatment, you must do something to get the proper compliance in the surround.

    Didn't see that coming ...hmm -

    The S7R Monitor System consists of the LE15A Woofer, the PR15 Passive Radiator,
    the LE85 Compression Driver + HL91 horn, and the LX5 Crossover.


    Those parts are in old home made cabinets that look dusty -
    can't tell from the few photos if they have been banged up a bit,
    but they are large and awkward to ship cheaply -
    the system is too old to be much of an audiophile's dream.

    The LX5 crossover network is an older 2way design and the capacitors
    will have aged and need replacement ...
    Its got a deprecated woofer with hardened Lansalloy surround ...
    and the tweeter is in unknown condition ...

    couple hundred, maybe, if you can find the right buyer in your market.

    Probably worth more to keep and enjoy than to sell -
    its not an undiscovered pot of gold ...
    but it could be a lot of fun to listen to !

    I dunno - I could be wrong, that has happened before.
    You are free to try to sell them and see what happens in your area.

    I live in the Wash, DC market and I've tried selling a couple pairs of speakers here recently -
    some sold, some didn't. Audiophile sales here have been down for the last couple months ...
    and the economy is kinda tough all over ...

    This is old hifi gear without much high frequency extension,
    (its an old 2 way system - the passive is not a real "driver")
    and its in older home made cabinets, which are not high value to the larger market.

    Like I said - if you find the right person that really WANTS something like this, maybe you can get more
    but I don't know where in Canada you are or what your local audio market is like ...

    The other question is - do you like the way they sound?
    They could be a fun pair of speakers to keep.

    If you're not going to keep them, parting them out would be the way to go. I would think the individual components should bring in some reasonable cash! Check on ebay and see what they are going for.

    As a complete system... not much. If you remove the components, you'll get $500-$1000 for the lot, sold as pairs of LE85s, LX5s etc.

    i tend to agree with the above posters...
    in whole, the parts are worth less than assembled, in all likelyhood...

    (which is a shame, IMHO)

    are you willing to share how much you have in them?
    we'd be interested in knowing what the market bore in your area...

    I don't see a notice stating that we give free appraisals to ebay flippers here. Maybe we should stop doing it.

    What's the harm?

    Some months ago I was asked by someone to sell off his complete Meridian system. I had to go to a Meridian Forum to find out what I had and how best to sell it off... ultimately one of those forum members bout the lot from me and is piecing it out himself. Admittedly, because of my experience here I realized in advance there are those who don't appreciate "flipper's" questions so I stated up front what my intentions were.
