JBL L 90

Hi,

Does anyone know where can i find some information regarding the JBL L 90 loudspeakers.
I couldn't find any information on the internet. I was told these speakers were produced in Denmark.

There's a whole series of speakers JBL made in Denmark, but as far as I know no one has ever been able to find any real info on them. I've got a set of TLX-60's new in the box that were made in Denmark - 'plan on selling them one of these days. They seem fine, I just don't have any use for them right now... They seem to be a cut above the consumer level speakers JBL was making in the U.S. at that time, though still nowhere near pro level.

Those speakers where extremely popular here in Germany. Paragon posted some information and is the expert concerning this speakers.

I owned them but the low end was simply not existing.

I got a pair of L 90, great speaker.
I have also tried to get some more info on these speakers, especially why JBL decided to have this series of speakers (L80, L90, L100) designed and made in Denmark.
More info about this would be very wellcome.

Thanks

WOW! Thanks for the excellent info!

As I said, good speakers but low end was lacking.

Where can we get technical manuals?

Believe me, it is working down to 40 Hz, measured in a 6.5 X 4.5m Room with HiFish-AC. And that`s enough for me. A big (bandpass sub with two 2205A)
may put more low`s , but i doen`t need.

You're right Eckhard!

I'm just addicted to bass. I have 2 250ti at the moment or my new years eve party setup with 2 4425 plus my double 2203 woofer.

And I still need more... 4435's

The L90 was just too small for me

Eckhard ; Thank-you very much for posting these beautiful scans .

It is always, most appreciated .

( Guido; here's the tech sheet for the L90 )

- Remember , this ( L90 ) is designed as a "smallish box" , book-shelf type speaker .
- To find what this le120h-1 is fully capable of in the VLF department , one would need to explore other box/tuning options.
- Giskard has previously mentioned for tuning purposes , to treat this woofer like an evolved 128H.

Earl, thanks for the ts.

I wonder why they do not have a cone kit for this 120H. Is this core interchangeable with other cores?

The last ones,

I wonder why they do not have a cone kit for this 120H

- That "NLA" policy was changed after the posted "ts sheet" was released. I've even seen these cone kits sold on eBay. One of our active posters bought one. In the future; I don't know how long JBL will support this driver by making recone kits available. ( A while back, I had actually thought this woofer was destined for use in the Project Array series. Since an Array1200 model didn't appear / I no longer have speculations on that subject ).

Is this core interchangeable with other cores?

- As long as original JBL recone kits are made available, that's all I would use.
