LE5 Theile/Small

[hector.murray]

Does anyone have Theile/Small parameters for LE5-5,6 & 9 ? I want to plug the info into BB6P.

Maybe Zilch will run some numbers for you with his WT2...Heh. Giskard is closer, and he's probably got a standard test box for 'em, too! :D

LE5-5 should be the same as 2105H... got some specs from one of my old databases here:

JBL 2105H:
Fs=200 Hz
Qes=.65
Qms= 3
Re=6.1 ohms
Pdia=3.98"
Vas = .03 ft^3
Xmax=.06"

Likewise, the LE5-6 should be the same as the LE5-10...

LE5-10:
fs=250 Hz
Vas=.028 ft^3
Qes=1.6
Qms=3
Xmax= 1.5mm
Re=6
Pdia= 3.98"

Mind you, this is OLD data... so I'd recommend double-checking before using it as gospel. But, it seems to "mirror reality" pretty well, as to the behaviour I've seen from those drivers...

Regards,
Gordon.

The 2105H and LE5-10 are listed in the reference chart below, probably the same as Gordon listed, though- David F

Thanks Gordon & Dave. I had seen the 2105 in the list and knew it would be the same as the LE5-2, but wondered if the differances in the 2105 and LE5-5,9 and 11 would be much of an issue to the software, since I knew there is an spl differance in the drivers.
