My opinion is that we often don't take in account the listening room. My experience is this: I have two speakers similar to the 4344 equipped with two 2215 woofers, the past year I blown one woofer...
I don't know if it really works, but, looking at the schematics, I never understand why this technique is applied not only at the capacitors in series with signal, but also to those in parallel. Any...
I have an original C8RLE15B kit, I can take some measurement from that, if helps, let me know.

I suggest you to check the dc resistance at voice coil exit before proceeding, the repair is not difficult, it could be easly done if you have little manual skills, sure is much easyier than removing...
Did you get the 9 ohms on both or only the LE15A?
For the open LE15B it could be the lead wires from cone to binding posts, check direct on the cone at coil exit.
If you are lucky is possible to repair, had the same issue years ago on a beyma.

Nice job, they look beautifull!:bouncy:
Just my opinion, to be in Europe 2000€ is a very good price, but it suonds strange to me that the seller accept to receive the second half of the payment after you receive the speakers, be sure that...

Those look very nice! But I don't see any reason to change the woofer and the driver in the actual system, just want to biamp it in the correct way.
By the way this is the xover schematic of my...
Hello all,
I know this is an old thread , but I was serching for info about bi amping a four ways studio monitor, and this seems to be the most recent one.
I built a 4344 “like” based on the...
Yes, I mean 2402/4/5H; thx for the answer!
THX for the info! I also need two "tires" for the 240X, can you tell me where I can check? THX and Bye!
Thanks for your opinion! Did you try different diaphragms? (2450, 2452 SL, or others...).
In case I have two 077 in perfect condition that I can add, but first I want to try two ways only. The...
Yes the middle picture has no original screws and washers, but the diaphragm is the same, it does have the sticker on the top, look better at the picture.
I will investigate about the different...
Ops, right, they are 2445J! Not H, THX for the answer!
Hello, I recently bought three 2445 drivers for a good price, (I hope!), can somebody of you experts tell me if the diaphragms are original?
One more question, of course the internal foam need to be...
THX for the info! Did you try any tube xover?
I built a 4344 "like" clones and I drive them active using two pass aleph 2 mono blocks on the top, can you tell us more about your xover design? Thanks!
They were very common in Italy in the 80s, me and my brother built two units at that time, that we still have, (look at my avatar), we had the drawings from the official JBL distributor and use two...
For anyone interested, received two kits this week, first thing I noticed is the external cloth surround is glued on the front of the cone, took a couple of measurements on the dimension of voice...
077 was the home version of 2405, used for example in jubal and L300, both are alnico, but the 077 have blue diaphragm. 2405H is the ferrite version of 2405. I have both, (077 and 2405H) they measure...
Hello everybody, short question about 4344 and other 43XX monitors since my carpenter is near to complete the job, the correct finishing of the back of the speaker is black paint, right?
THX...
