Greetings, Friends,
Both in the book, "The JBL Story", which I am very much enjoying, and also in the 1975 JBL Home Speaker Catalog, to be found here at LH, there is mention of an "L400". Does anyone know what that was supposed have been? I'm very curious about this "L400", and would appreciate any information that can be shared with us. Thanks, very much, and God Bless!
Every Good Wish,

according to this page:
Above is an excerpt from JBL's 1975 catalog illustrating a "mystery speaker" referred to as the L400. The only description says, "Coming soon. The L400, with the promise that it will be the most exciting fusion of art and technology yet presented by JBL." It never came.
Originally, the speaker was planned to be a domestic conversion of the 4340 monitor, similar to the L300 conversion of the 4333 monitor. It would be a four-way speaker using a 15" low frequency driver, 10" midbass, 1" throat compression driver midrange and slot tweeter. The main development work in converting this speaker for domestic use centered on network design changes, a revised midrange horn and aesthetics suitable for a home environment
There were three separate attempts to bring this speaker to market. All failed before a final decision was made to cancel the project. The primary difficulty was developing a system that could be sold at a reasonable cost. However, there were also technical issues and no one was satisfied with the ultimate sound of the prototypes.
Yep, my book says the same thing ...Originally Posted by pos
But I think Doc was asking if anyone had anything EXTRA to add to that -
maybe some firsthand info, or perhaps an interesting tale to tell ...
2ch: WiiM Pro; Topping E30 II DAC; Oppo, Acurus RL-11, Acurus A200, JBL Dynamics Project - Offline: L212-TwinStack, VonSchweikert VR-4
7: TIVO, Oppo BDP103D, B&K, 2pr UREI 809A, TF600, JBL B460
I never really looked before, but I am pretty certain that the photo is of a 4340 or 4343.
I think that statement about horn changes, crossover mods, and no one being happy with the ultimate sound of the system is extremely telling. It relates to this thread and many others that have come before it: http://www.audioheritage.org/vbullet...ad.php?t=22207
As 4313B has said many times, these professional monitors simply were never meant to be plug and play. They were typically soffit mounted, set up by experts, and EQ'ed using then state of the art gear. To take a 43XX monitor and throw it into someone's living room is not at all an easy proposition... with great care and effort many of us have made them work out well, but had JBL offered them as a product to the general public, there would have been many problems. I think they made the right decision to shelve the design.

When I look at it, I almost see a 4350 on it's side???
"Vertical 4350"
John, saeman already made your dream come true:

Hello, POS, and Heather,
Thank you for that information. I, very likely, would not have found it anytime soon. Is there another JBL book, besides the 60 Years book? That's the only one I have, but I'd certainly like to obtain any others that detail the JBL years, "back in the day". It's very interesting to read about the "L400", and I appreciate your having pointed me in the right direction to see that info. Heather is right, too. If anyone out there was a part of the original plans for the L400, I'd love to hear of your recollections of that never-realized project! Thanks, again, Friends, and God Bless!
Every Good Wish,

Plus I believe it was around the time the public was turning there back on refridgerater sized speakers.
