    2003 thread

    I need not worry about dates here, these are VINTAGE speakers and its OK !!!

    My JBL 4311WB speakers have sat in the attic for the last 25 years with a busted
    mid and tweet. I bought a soldering iron and guess what the internet allowed me
    to do after all these years.........FIX my speakers and now they started working
    and Im playing Jethro Tull Benefit and loving it !!!!!!!! Scorpions are alive again!

    I thought they were 4311B's for years and years and when I just looked at em,
    I couldnt believe they were WB (11644 and 11645 serial numbers).

    I have no idea what magnets or any info, but I would like some advice as
    to what amp I need to make this work at an ok sound????

    I was going to buy a new PYLE 240 watt amp but the freq response is
    not good and its rated in peak watts, not rms so its really not 120 per
    channel watts. DO I need 100 per channel or would 40 be ok ????

    I see a Onkyo 60 watt per ch for 40 bucks on craigslist........what is best for
    the speakers????? Thanks for info (im so happy to have them working again)!!!

    In the JBL pro catalog the 4311s were rated at 40 watts continuous... ratings and specs are only useful to a point. I certainly wouldn't buy the Pyle... the Onkyo might be a great deal or it might also be a pile.

    Amps like speakers do degrade with time. I use a refurbished Marantz 2275 with my L100s and I doubt more power would really make much of a difference. Do realize there is essentially no difference between 60 watts and 75 watts, however the difference between a great 60 watt amp and an average 75 watt amp might be huge... I don't think the 4311/L100 will really do a great 60 watt amp justice though so sticking with something like an Onkyo, a Marantz, a Denon, or a vintage Yamaha or Pioneer should all give you very satisfactory results.
