    2216nd-1 available

    Interesting for in style of 4367 But I guess the 4367-Wg never will be possible to buy.

    No loss there.
    I do find it very interesting that JBL is allowing these parts to be sold. They have certainly oscillated on their policy recently.

    For us this is great, it breathes new life into the forum.

    I would be curious to see the T/S parameters of this -1 version, or better still a full-blown EDS !

    Bummer that part number does not show up on the pro side of JBL parts.

    Barry.
    If we knew what the hell we were doing, we wouldn't call it research would we.

    Free air impedance

    I visited my friend and we did measure 2216nd-1. I am posting results.

    Hi zeljkor,

    Nice to be seen, but please, send us full recalculated T/S data, so can be used for the projects....

    T/S data measured from the first driver:
    Re = 5.556Ohm
    Fs = 28.26Hz
    Qts = 0.376
    Qes = 0.397
    Qms = 7.12
    Le = 0.461mH
    Mms=134.1gr
    Vas = 332.8liters

    T/S data measured from the second driver:
    Re = 5.52Ohm
    Fs = 27.59Hz
    Qts = 0.3572
    Qes = 0.3776
    Qms = 6.589
    Le = 0.4703mH
    Mms=123.8gr
    Vas = 378.4liters

    I am not sure how much my data is different from factory specs since they are not available.

    Nice to see some T/S data for this woofer
    but why is so much different in Mms between both woofers, thatīs strange?

    Driver with lower fs was working around 2 hours in free air (20Hz , 3V applied). I suppose this influenced measured data. The second one was "cold".

    because MMS is calculated from the impedance sweep, deviations in measurement could influence the calculation. Big difference but may not reflect a real difference of ~10g.

    Thank you zeljkor!
    Interesting, this thing seems to behave similar to a 2245H
