A Few(!) Questions About JBL L100

[Koosha9876]

Hi everyone!,
I'm a new member at this site and I hope I'll learn useful things from the members' knowledge and experiences...Now let me jump to my question, shall I ? :
From what I've learned, there are 4 versions of JBL L100 :

1)L100 Century with grey JBL logo(and vertically aligned units)
2)L100A Century with grey JBL logo
3)L100A Century(Late Model) with orange JBL logo and network control settings from -5 to +5
4)L100A Century((Very!)Late Model) with orange JBL logo and network control settings from 0 to 10

Am I right on what I've written?If so, what are the latest drivers JBL used on the 4th version in the last production run?from what I've heard :

Low Freq Driver : 123A-3
Mid Range Driver : LE5-2
High Freq Driver : LE26

I'm pretty sure they gradually updated the tweeters from LE25 to LE26.., but didn't they change 123A-3 or LE5-2(ex. LE5-2 to LE5-10 or...)?

sorry for my long questions!, any help of yours is truly appreciated

Regards,
Koosha9876

L100 always used le25. Also I think the later ones were not labeled "century"??

Hi Koosha,

Welcome aboard ! Maybe you forgot two versions ? L 100 T and L 100 T3 with 2214H woofer. Regards,

Maybe forgot, but in my mind and probably many others those are not "L100s". I would suggest the JBL LSR32 and current LSR 6332 monitors are more closely related to the L100s if you want to expand beyond the original 4310, 4311, and corresponding L100 versions.

I'm reasonably certain all later L100s used the LE25 and LE5-2. Not sure about the woofers.

Hi Script56 from TN(King ELVIS' state!),
Yes, the later ones weren't labeled "century" anywhere except on their owners' manuals but I still consider them "Centuries"!
Are you sure they never changed LE25s?cause I've seen some later L100As with LE25-2s,LE25-4 and LE26?!

Thanks!, Richard and nice to meet you
I think the suggested versions aren't considered L100 Centuries but the woofer you mentioned is an upgrade from 2213H woofers used as an alternative for 123A-1 and 123A-3 woofers...
Am I right on the other 4 versions???

I completely agree, Mr.widget but did I mention all "L100s" in my first post? weren't any other versions produced?
I also thinks they didn't change LE5-2s,but weren't LE25s later changed into LE25-2s,-4s,and even LE26s? and maybe someone can help us with the woofers?!

Thanks again

Hi Widget

Here is a review of the L100T
http://www.hifi-classic.net/review/jbl-l100t-167.html

There is a link to the L100
http://www.vintage-speaker-review.co...l-100.html?m=1

Some might associate the L100T due to model number designation with the L100 but is a totally different loudspeaker

Reference to the JBL product profile in the Library and elsewhere confirms this.

We have been through all this a while back when Bo bought up his college years with the L100

Don wrote an excellent account of the whole reason behind the L100

It was JBL move to push into Altecs 604 long held dominance in the studio business

It was voiced to mimic a 604 midrange peak

As a loudspeaker the L100T is nothing like that

Far from being critical but Richard your post was in accurate.

Hi Ian, Thanks for these useful info
so, putting aside L100Ts...Did JBL produce 4 versions of L100s?Can you help us with the latest drivers used in the 4th version in its last production run?
Were the crossovers anyhow modified from 3rd to 4th version?

Unfortunately l don't have the time for a detailed account of the differences but if you read the above link it will give an insight

Most if not all your questions can be answered by looking in the Library product profiles and the reference area of the public forum

Didnt first L100's actually use LE20-1's ?

Can you advise the intention behind your questions?for example are you trying to buy a used L100?

Yes the original L-100 with vertically aligned drivers did in fact use the LE-20 tweeter.
I had a pair. It's cone was slightly larger in diameter than the LE-25 tweeter.

The LE-26 never made it in to an L-100 that I saw, and I sold hundreds of them back in the day.

The L-100T was similar in model number only, as mentioned by others.

Yes, I am
The vintage stereo store I'm intending to buy from has got 2 versions of L100A(Later Model-orange logo)...1st one has -5 to +5 and the 2nd one has 0 to 10 scale...I just wanted to know with one is the latest?(I couldn't find any technical info anywhere about the second pair)and Is it normal that the 2nd one has LE26 tweeters,LE5-10 midranges and 2213H woofers?(Cause I want to buy an "UNCHANGED" pair...)
I'd be happy if anyone shares some clear info
THANKS

Thanks for the info, my friend
but weren't any of the later LE25s, like LE25-2,-4,-6 used in later L100A(Late Model)s ?
