4313B questions

[tweeter]

Hello,
I´ve 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´s a caprice). Can anyone help me to search them?
Thanks.

Absolutely brilliant for 150 euros! Did you find them in Spain?

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?

Why not just let them play with the surrounds installed as they are? YOu can always re-cone later. Or just wait for a pair that don't need that much work. It would seem you'd be spending less money to get a complete pair rather than "jacking up the gas cap" as car restorers call it.

That's gonna take more than tape! Where's that shot of Scotty our LH hand-model?

Hmm, lovely mirror-imaged 4313B's don't appear very often in Europe to say the least . Worse case scenario is the 066 is unrepairabe and he needs to track down another. But, IIRC, he could stick a pair of (easier to find) 044 in their instead. Not too much work for such a great speaker .

Hmm, these need woofers and one tweeter. I assume you're not referring to these as "lovely" except in their potential. I guess I'm thinking either do it right or keep looking. Which may be exactly what the OP is thinking. More power to him for wanting to bring a classic system back to full-voice!

[Ralph856]

Hmm (again), I'm saying LOVELY as is, especially for 150 euros!

The cabs look fine from the pictures (although difficult to tell for sure), the woofers possibly only a refoam. Even recones would not be OTT considering the purchase price. The only potentially serious issue is the tweeter (IF not working), and even that can be remedied by using 044's. Or looking hard for a 066.

Oh, I forgot. You prefer L112's .

[BMWCCA]

Oh, I forgot. You prefer L112's .

But I also own L96s!

I normally drive my BMW 525i but I also enjoy my '64 700 convertible, or my '87 535is. Life's too short to try everything, but trying makes it much more fun!

I hope you get 'em and a simple finger-poke fixes your 066. You'll never know until you try.
Lord knows not everything I buy is in perfect shape!

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.

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´t 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).

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´ve 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´t 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´ve applied the same technique to a mid with the same issue.

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

That looks to me like contact cement ( the yellow colour ) If you get some Zippo lighter fuel and a cotton bud you can test out on some of the excess to see if it will soften. You will not harm the cone with this.

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.
