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

Thank you so VERY much.

No "Xmax"...?

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.
