    Average cone/fram life - SR systems???

    There has been speculation here that JBL may decide in the future to discontinue selling replacement parts necessary to service older professional components.

    In thinking about this, I began to wonder if this would significantly disadvantage folks in sound reinforcement businesses.

    I assume the varaibles that come into play when deciding to buy a new driver or re-cone/re-fram on older dead unit, include:
    • Cost of a new driver compared with re-coning/re-framing
    • Time necessary to perform rebuilds
    • Finding competant service folks
    • Frequency of blow-outs
    • Underlying cause of failures (physical damage Vs. excessive excurtion)
    • Feasibility of using knock-off repair parts
    Before I became a bean-counter about 30 years ago, I was in the automatic transmission rebuilding business. Apparently, rebuilding transmissions is not very common today since the technology has become more complex and swapping in new factory units is now the preferred method of repair.

    So anyway, if the JBL drivers made today are very ruggid and can take lots of power, is it a disadvantage if occasionally you would need to replace a driver rather than have it repaired?

    I assume your "average component life" would be a major consideration but I assume this has increased a ton in recent years.

    Everything you do costs you something.

    Even though the of repairing JBL is high the cost new JBL is = to or higher.
    This is why the big used market for JBL products.
    There are some very good independent speaker repair shops, some are members of the forum.
    Some Pro sound companies have their divers reconed on a regular basis, usually in house.

    The 2412H-1 is throw away JBL driver, no parts from JBL only the whole unit.
    There are after market parts by other vendors, so there is a market.
    Don't take this personally but maybe the BCs at JBL figured there is no money in parts.
    But here you go.

    BCs or MBAs?

    BC's for providing the financial data...
    MBA's for having 'the vision' and forsight to remove all
    operations that do not "add to the bottom line"

    hard to say which is worse....

    a beancounter too...
