Thread: 4313B questions

Hello,
I磛e found a pair of 4313B for sale.
The general shape is acceptable, except one tweeter dented and the woofers refoamed on the front of the cones.
Is it possible to remove the foam without damage the cones?
Are compatible the white woofers of the L96?
I also have a pair of 4301B. What sound differences should I expect?

Thanks.

Hello,

- Buy them if the price is right .

Is it possible to remove the foam without damage the cones? Are compatible the white woofers of the L96?

- Truly talented reconers such as LHF member "edgewound", can do this surgery ( though it's not cheap due to the labour involved ).
- I wouldn't try it yourself until you have gained lots of hands-on experience at refoaming various woofers.

- The white coned le10h-1 sounds the same as the black coned le10h .

I also have a pair of 4301B. What sound differences should I expect?

- Don't know since I have neither .

Hi, some pictures of the speakers. I will pay 150 euros.
I will need blue cloth, one 066 and probably I will swap the woofers for the LE10H-1 white ones (it磗 a caprice). Can anyone help me to search them?
Thanks.

Hello BMWCCA and Ralph856, thanks for your comments.
The cabs are ok, only a sanding and refinish of the veneer is needed.
Appart, the grill cloth is damaged, so I need to replace them.

Why white? Get the woofers properly refoamed (at a really trusted speaker repairer). The correct roll is ~ 3/8" (9-1/2 mm) wide. Or get them reconed, as kits are still available. You should have the option of white (LE10) or black (LE11) cones, I think, but someone who knows more can confirm..

Is that 066 non-functioning or does it just need its dome carefully pulled out with tape?

Yes, I found them in Spain (what a lucky), as I found a pair of 4301B, that after restoration they looks as new and the sound is marvelous.
I think the woofers works ok, but I don磘 like the foam in the front of the cones. If I decide to search a pair of LE10H, I prefer to purchase the white ones.
I think the 066 works but If I cannot repair the dome I will need to go for another unit (hard search).
More pictures of the tweeter:

Take a piece if wire or even a tooth pick, have it at the ready. Make sure it's not sharp. Take a dab of hot glue and place it right in the center of the collapsed dome. Put the stub end of the tooth pick in the dab and let it cool while you hold it. Let it cool enough that it will stand up while you walk away. When it's very cool grab the tooth pick and slowly pull it back till the dome comes out. Once thats done grab that gob of goob like a you would a bugar with your finger nails and remove it from the cone. You may have to do it a couple of times but it works. Worse case scenario is that some of the paint on the dome comes off. If that happens just mask off around the dome and paint it with silver spray to match.

Don't worry about parts, they're still around but a lot of the time people who have the LEh-10H and the 066 tweeters reconed are waiting for the economy to get better to sell for at least what they have in it. I don't believe there are any black face woofer cone kits from JBL left.

I磛e got the speakers at home.
The first approach has been to remove the woofers.
Altough they are both LE10H, the terminals layout is different. Why?
By moving manually the cones, seems too rigid and one of them rubbing.
I don磘 know if the foam is the correct or perhaps the wrong layout in the front.
The tweeter dome has been repaired with the aid of a electrical tape.
Sticking the tape softly and pulling out quickly, easy and effective.
I磛e applied the same technique to a mid with the same issue.

The foams are from Simply Speakers.
I don磘 know the nature of the glue, so I磎 not sure about the removing....

You sure? I think I would just use as is if they are working or refoam but your never going to get that cone back to original.

Recone is the only true fix.
