Could someone indicate, according to his opinion and personal experience, which is the woofer JBL 12" which has the best sounding, best linear response and greater sensitivity, regardless of the date on which it was released?
Thank You,

In my opion the Jbl D123(98db efficient) has great sound and is the best, except for being a little weak in the extreme low end.I'm sure some other members on this forum will disagree with me -RUDY
One question remains though. Best for which purpose?
Right! I liked the ME120-H (I think that was the model number) in the S/2600 2 way speaker......The woofer re-produced a lot of midrange as well so not made for really low energy although it seemed to operate quite well for me at the time.Originally Posted by Lee in Montreal
Careful man, there's a beverage here!
I think at 1200fe is the best 12" woofer JBL have made
As long as we have no idea of context, let me voice my praise for the 128H-1.
In a totally different application, I'm equally fond of the LE120H-1

For the purpose of producing the best bass on my system.

Hmmm... Okay then. And what is your system? What do your use it for? In-car sound system? Studio monitoring system? PA system? Home theater system? Horn loaded? Bass reflex?
2-way? 3-way? 4-way? How high do you want the woofer to reach? You want best hi-fidelity? Best power? Best low end?
You need to help us if you want a specific answer...

If it's low frequency you're craving, then the JBL part no. 336063-001 alloy woofer with rubber surround is the ticket. This shielded 12" wonder is costly if you can find it, approaching $800. It's found in the HTPS400. I've never seen a model number for this driver.
Lacking the money and the luck of finding a 336063-001, I'd go for the LE120H-1, which is found in the L7 and the S3S Synthesis® Three subwoofer.
Out.
Considering the mid is already a 12" driver, I would fill the lower box with a JBL W12GTi sub driver (20-60Hz). Enough sub bass to shake the building.
Looks like you have plenty of room for a 15-inch in that box . . . or maybe even an 18 . . .
Sure, if you don't want to go fast, or expect it to handle well. Sort of like using a D123 and expecting deep bass.A Mercedes-Benz is the best vehicle on the autobahn... but sucks big time for cropping corn...

It is not that I need because sub-bass already have a subwoofer Dahlquist for this purpose. What I'm wanting is an option for the bass and mid-bass provided by my current D-123, which are already very good. You know how it is, we always have curiosity to try other good components in the system.

I'm surprised it took five posts to effectively end this thread. I guess not enough folks have had the exposure to this transducer.
The only complaint Greg seems to have is the lack of a four-inch voice coil, hence the preference for the fifteens. Personally, I think it redefines performance of three-inch coiled twelves. It's pretty stunning with a real nice balance between low frequency extension, efficiency, ultra-low distortion, and superlative midrange. A note on the four-inch coils, rumor has it JBL is moving away from them in favor of the three-inch coils as found in the new 2216Nd. That said, the new 1501AL-2 and 1501AL-3 still sport the legendary JBL four-inch voice coil. They basically redefine state of the art in JBL fifteen inch transducers.
Interestingly, the new ten (100FE-12) is also very good. Jerry loaded it up with all the goodies too. It looks like a ten-inch version of the 1200FE-8/12. While it is made in China, JBL forced the vendor to strictly follow process and procedure.
Of course, all this is pointless, you can't technically buy them. I guess the thread should have been titled "JBL 12" - Best Woofer if one can't obtain a 1200FE-8 or 1200FE-12."
How hard is it to get a pair of these drivers?
Seems the best plan would be to build a pair of cabinets and do the distributed bass thing ...
