The 2012H is the more advanced design and is an improvement over previous designs.

The 2122H is better in a 4344 or 4345. It is not difficult to build 2122H's. In fact I just built eight of them in the past two weeks.

If you locate clean E110, 2122, or 2123 cores you can have an authorized JBL recone shop put new 2122 kits in them and be good to go.

Alright Giskard,

But did you compare them by listening ?

Thanks,

Hi
I've used both the 2122 and 2012 in my 4344 clones. Giskard is absolutley right about the 2012 being an advancement. Using the 2012 with equalization it sounded quite good in the 4344, but following the original design the 2122 does a better job gelling the system together. GT has hinted that the 2123 might voice even better, but I am sure it would take a modification on the original crossover design.

If you guys want 2123H's figured into the scheme too then I need a pair sent to me. I'm not going to build a pair on my dime. ;)
2012H's too if there is an interest in them.

Here is my take on the system as a whole. The LF and the UHF shouldn't be messed with. The 2123 and 2012 can possibly be nice alternatives to the 2122 with network tweaks. The fog horn/c.d. combo has a few options as well again with network tweaks. Let me know what you guys want to do.

Ok guys,

I would like to use 2012H for home theater front loudspeakers.
I seek THE JBL cinema medium sound... ;)
The sensivity is good 100db.

So, where can we found 2122 ? On ebay for exemple ??

Thanks,
