View Full Version : Model variations 43xx/L100

Hello people

I have a great pair of L100s and I'm about to buy a pair of 4312s ... well , I'm suddenly in doubt, because today i was offered a pair of very well kept 4311s.
But but but ... I find it increasingly difficult since I see variatens in the front layout within the same model.

Should this tell me something about production series, age, place of assembly or ...?

I found this image: http://www.audioheritage.org/images/jbl/extracts/l100-431x.jpg

It's a 4311 to the left. Did they come in mirrored pairs? The pair I've been offered are identical, not mirrored.

Number two from left is a L100 - I have pair of those, they look like that. But I've been offered to buy a pair of L100s with this "alternative" layout:


Any comments?

I'd also like to know the difference between 4312, 4312A and 4312 MkII

And I'd like to know a bit about powerhandling, impedance, sensitivity for L100, 4311, and the 4312 models. Do you know where i can find these specifications?

I hope someone in this group can help.

Kind regards,
