    T-S Parameters for 116H-2...?

    Anybody got 'em?

    This transducer is not on the June 2001 JBL T-S Parameters compilation.

    Help?

    Thanks.

    116H-2
    May '86

    Fs = 34.6 Hz
    Re = 4.58 ohms
    Qts = 0.352
    Qms = 8.66
    Qes = 0.367
    Vas = 52.9 liters
    Sd = 0.0198 sq meters
    Bl = 7.8 T*m
    Mms = 22 grams
    Le = .62 mH
    no = 0.57 %
    Pe = 100 W
    Flux = 0.92 T
    Motional Impedance = 113 ohms @ 35 Hz
    Minimum Impedance = 5.4 ohms @ 250 Hz

    Response is "good" up to about 2 kHz

    Nope, that line is blank. I doubt it is greater than the original 116A at 4.826 mm though.

    I'll go with the 116A spec for that, until we know better.

    116A looks very slightly better - i.e, slower roll-off - hitting-3dB at 36.2Hz (vs 116H-2 at 39Hz) in same 39.415 L enclosure (WinISD). May not be signiticant/real audible.

    Have your ears experienced either in any application?

    As always, thanks.
    Good weekend...

    Well I was always a fan of the little L19/4301. I never much cared for the L40t3. I think my opinion had more to do with the networks and HF drivers than the 116 variants.

    I concur, but would venture one step further - that the L series networks are less robust than the 4xxx series, and so for any otherwise comparable pair, the later are preferable to my hearing.
