4435 Cabinets arrived

[Guido]

FINALLY I've got them :bouncy:

The carpener delivered them today. Yes, the pics are crap and the cabinets are still full of dust but I needed to do some quick shots to show them here. I think you understand how I feel ;)

Will post the progress here.
2 2225 cores still need reconing to 2234 but the kits are already waiting.
One crossover isn't finished. the other one needs testing. They are CC of course.

[mech986]

Hey Guido,

The cabinets look nice! Your carpenter looks like he did very nice work although I'm sure the wait was tough. Let us see them again after you've had a chance to clean them up or when you get the fiberglass installed.

Good Luck!

Regards,

Bart

For testing purposes sure!

Tested will be:
Ti Dias
Al Dias
Beryllium Dias
2435 on PT-H

and maybe Aquplased types.

But first the homework, damping, crossovers....... Puh

Some ideas how to manage the installation of the L-Pad and Rheostat to the L-Pad Baffle.

[spkrman57]

Those are great looking and can't wait to see the final product!

Congratulations on a wonderful project you can be proud of!:applaud:

Yesterday I measured the crossovers.
Voltage drives:
Red: 2234
Blue:2426
Green and light green: crossover modification for 2435

[Guido]

Couldn't resist to measure the 2435 :D

Red: 2426 / 2344 with 4435 crossover set to zero. Don't know where these two peaks come from. Brandnew diaphragm installed, this might be the reason.
Blue: 2435 / PH 316 with modificated 4435 crossover. Looks good!

[frank23]

hi guido,

the curves look very nice!

what is the PH 316 you are using with the 2435? Is it the P-Audio horn? I am still waiting for my PT-H1010HF horns to match my 2435's

currently I am using the 2344/2420 and I am very curious to what the 2435 is capable of.

Yeah! :D

Frank

Yes it's the P-Audio. It's not as good as the 2344. I would say 80°x80°. But I'll try to narrow the slot to improve it.
Today I drilled holes in the cabinets and didn't forget to drill holes for the PT-H1010HF as well. I'll check both combinations
a) 2435/PH316
b) 2435/PT-H....
Until now I didn't play music through the 2435. I'm very excited about this. The curve looks so smooooth :smthsail:

to be tested compared to 2426 + 2344 + original 4435 crossover (red curve)

Hopefully I'll finish the 4435 this weekend.

[Zilch]

Yup. When I tried that, it was obvious PT-H1010 had much better pattern control, so I shelved the PH-316's. They worked better rotated 90° (the "hourglass" orientation); I don't consider the vertical dispersion so important, but they do look weird that way:

Wanna see your PT-H results, of course, with both driver/crossover combos. :bouncy:

Hey Guido! ... Can you hear the doorbell? ... No? ... Well maybe later this year you will. Guess who will be on your doorstep.:bouncy:

I think I know who. But I'll not sell them :p

You and your wife are always welcome. Just give me a hint before to make sure I'm there. We have a big house and a lot of space now.

Ditto Guido. Always welcome. We will see if we can make it.

[Guido]

Some pics about the progress.
The cabs are wired and ready for speaker installation.
Tonight I reconed the pair of 2225 to 2234.
2 more original 2234 and the 2426/2344 are waiting.

The CC crossovers are BIG :D

Oh.. I love that veener

[Chas]

Beautiful Guido! It must be difficult to wait until completion. I hope they exceed your expectations. - Wait a minute, of course they will...they are JBL's..:p

Viel Glueck mit Deinem Projekt!

[mick c]

Hi Guido, I have a pair of 4435's that I am restoring now. I will post some pics next week sometime to show their progress. I have had the networks checked out and reconed the 2234's. The 2426's and horns are in mint condition so I will leave them as they are. I opted to change the veneer to a artificial charcoal grain to suit my decor. The front baffle will be done in a matt black 2 pak finish. When I purchased my speakers they had no grills so my cabnet maker has made them as well, so I will post pics of them as well. In closing congrats on what looks like a very profesional job on your diy's.
p.s does anyone know where to purchase the cork gaskets for the 15" bass drivers in australia? (jands could not supply)
Mick..

Others may chime in here...BUT I haven't had any luck from JBL Canada with the cork gaskets. The Parts Express thin stick-on gaskets work well for me for mounting woofers.

[Guido]

The cork gaskets where in 3 MA15. Unfortunately I didn't manage to get a 4th one :banghead:

I believe they are NLA.

I believe they are NLA.That is what I have been told... I ordered several sets recently only to find out that they are NLA and there is no direct equivalent.

[Ian Mackenzie]

A tip.

I made some nice gaskets using a sheet auto cork rubberised material.

Just make a pattern using the driver outside diameter and front mount cut out diameter and carefully cut out the gasket with a sharp art blade.

If you are keen you can cut sections like the MA15 gaskets.

Some contact adhesive on both surfaces and you are away.

Hi Ian,
what exactly is that auto cork?

Hallo Guido,
geht's um die original Korkstreifen , die auf die Schallwand geklebt werden, bevor die Tieftöner eingebaut werden?
Wenn ja, hab ich die für dich. 07123-947985

Finished!
Just heard:

Yim Hok-Man

This dynamics are awesome.

I bought a nice sheet of it some years ago on a classic car gathering. It is cork mixed with rubber and seems to be an excellent speaker gasket material.

This is response for
2426 with original Ti Diaphragm
2426 with Aftermarket Be Diaphragm
2435 with original Be Diaphragm and modified 3135 network.
I'm still tweaking the network and will present schematic later.

2435 is my favorite and sounds exellent.
It seems that the Be dia measures "flatter" than the original Ti. I have no listening experience till now with the Aftermarket Be.

[Zilch]

http://audioheritage.org/vbulletin/showpost.php?p=113285&postcount=29

it seems the aftermarket 2426 Be diaphragms are performing a bit better once on a filter.

Or am I confused again?

Note also the little dip at 10 kHz with 2435. I've been looking there ever since GT mentioned it, and finding it universally present:

You're right! I need to listen now and this can take time. Too many dias...

Yep! Seems he was right :p
But I like the 2435!!! It is so clear and it sounds sooooo relaxed even when I push the 4435 with my GFA 555II.

Hi,

I have been sitting on a pair of 4435s without cabinets for years and it is time to do something about that. I want to modify the cabinet design to be more like my L150A, so a tower design with JBL blue fronts and Maple veneer.

I understand that each cabinet is 5 cubic feet net. But can anyone help me with the following specs, please?

1. What is the interior volume taking up by each woofer and by the horn?
2. Does the hon sit in a separate internal inclosure? It looks like it does from the cabinet pictures I have seen.
3. If #2 is a yes, does it then reduce the net size of the one woofer cabinet on that size (how big?) or has the been size compensation for the horn enclosure such that net volume is 5 cu ft on both sides?

Best regards, Bo

[hjames]

The lansing site is not a Super busy, high volume website. The folks with knowledge like what you seek are not online day and night.
Its really best to ask your question ONCE, then wait a day or two and see if someone answers.

Asking your questions in a number of old threads is considered spamming and won't get answered any more quickly ...

Patience is a virtue for a long term project like yours ...

Good luck with your build.

Haven't looked but also should consider starting one thread with your proposed design and questions, that way keeping all replies in one spot. Makes it easier to keep track of your information too.

[Lee in Montreal]

1. What is the interior volume taking up by each woofer and by the horn?

If you look at a driver's specsheet, its volume is generally mentionned.

Hi high123bid,

1. I think that several percent variation in the box enclosure would not produce almost any differences in the FR-response.
2. I think that the horn is NOT in the separated box, but a kind of driver fixing has to be done. May You can ask Guido (the forum member).

regards
ivica

[allen mueller]

The enclosure is divided evenly and on the horn side JBL added some additional fiberglass rolled up and tucked behind the horn to help compensate for the volume lost due to the horn/driver.
