View Full Version : Found some 4350's in an old discotheque...

First let me start by saying thanks to all the members of this forum. This is my first post, but the info here has helped me with my Altec/JBL addiction for the past few years.

I was hired to re-vamp a club system last week. The manager didn't want to spend any money on new equipment. She told me that there was a room full of old equipment in the basement. When I went down there, I was stunned to find a 1970's era private gay discotheque. The place was virtually untouched since it closed in the early 1980's. I spotted a JBL cabinet in the corner. It turns out that it was a 4350 studio monitor. Upon further scouting, I found a 2nd 4350 upstairs. It was being used as a support for a dancing platform!! I bartered both 4350's into the deal, along with a crown micro-tech! They are in poor condition, and I was originally just going to strip the components out and use them elsewhere, but after a bit of research I might make this my next loudspeaker restoration. I've been looking for a project like this since my girlfriend banned my VOTT's from the house.

Lucky find, but christ, what a mess...a crying shame to see something like that happen to to a pair of 4350's.

Looks like you have your work cut-out for you, the bones look okay from what I can tell from the pics.

Good luck, will you re-do them as 4355's?

Great story...using a 4350 to prop up a stage - I did chuckle when I read that.:)

The woofers are wrong.
Please check what they are and we will see if they can be reconed to the right ones.

Also it seems that some "experts" played around with the crossovers.

HI Axiomhead,

Welcome to LH and what a first post! Congrats on your finds and good luck with the restorations. Be sure to look all over the place for the grilles. You might find them screwed to the wall as decoration or covering a vent or another speaker, you never know.

Certainly looks like they've been taken apart and worked on as noted above. Those may actually be 4350A's because of the A designation at the end of the serial number, best to check if both are similar and not too far apart number wise. Check under the fiberglass, occasionally there is some documentation written or tucked away in cabinets.

Will be interesting to see what woofer you do have, 2231H's are in the 4350A while 2235H's are used for the 4355's. Both should have foam surrounds. Yours have a double roll paper edge so may be the wrong driver or was reconed. Hope you have a driver whose frame could be reconed to the proper unit.

Hope to see what the actual veneers look like. Appears they were painted black?

Regards,

Bart

YUK! They look like they lost the war!

Great find and I hope you have the time and patients to bring them back to sing again.

Hope there is no rush to get them going and you take your time because these will be gorgeous when fully restored to their original glory.

Expensive - Yes

Labor intensive - Yes

Look on your face when completely done PRICELESS:applaud:

The availability of the components will dictate whether these will end up as 4350's or 4355's. Personally I'd like to keep them 4350's because I have the 4350 badge with serial # already.


The woofers are wrong.

Also it seems that some "experts" played around with the crossovers.

The woofers are absolutely wrong... Which will probably be my biggest hurtle in the restoration (assuming the xovers are ok). I removed all the drivers today and below is an total inventory of the parts:

HF Comp Driver- 2 X 2440 SN#10842, SN#12732

HF Comp Driver Lens-2 X 2311 SN#11297, SN#11853

MF Driver 1 X 2202H SN#18182

LF Driver- 2 X 2205J SN#13750, SN#11696

Crossover- 2 X 3107 SN#11248, SN#10754

26869

The 2 ultra high freq drivers have no tags, so I'm clueless as to the model/serial. The crappy part is I know where the missing drivers are located, but they've been assimilated into a operating club system so retrieving them is not an option. I'll probably just wait until I find suitable drivers on my install adventures or at a swap meet. Untill then, the restoration of my 4350's will have to wait...

sigh.

I'd say it might be like inheriting $5,000 from a relative, then finding out debts and attorney's fees will come to $4,500. It's still a good thing, but not as good as it could be.

HF Drivers are for 4350. OK. You should exchange the diaphragms
MF Driver ok but needs recone. The parts are available. It shouldn't be a problem to source a second 2202H
Crossover needs check from an expert.
LF Driver, 2205 can be reconed to 2235. No Problem!
You also need lenses for the HF Driver
The UHF Drivers are 2405 and ok. You should exchange the diaphragms

It looks good but will cost you 2k.

Hi Axiom,

nice project....try to take your time for getting the right stuff.
Would be nice also to post the numbers of the 4350 badges. We can take a look for the age.

HP,

He did post the cabinet numbers in the first post:

Cabinet 1... no Serial #, has both HF, the mid, and one Low
Cab 2... Serial #11094, has both HF and one Low

I suggested he check under the fiberglass when he can, occasionally folks have found a cabinetmaker paper checklist tucked away which might have the serial number on it.

Will be interesting to check the condition of the drivers but for restoration purposes, and seeing they were run in a disco, diaphragm replacement for the 2405 UHF and 2440 HF compression drivers with a careful gap cleaning will be needed.

Those crossovers will need to be reviewed to see what modifications were done to them and then decide to restore or setup for multiamp.

Is the multipin Cinch plug seen in one photo OEM or likely added on and is it present on both speakers? Used for multiamp?

Regards,

Bart

Hi Guido,

Great minds think alike!! (Just kidding :o:)

Usually I wimp out and try to use just what's there to save money. But since its not my money, I'm just reinforcing the idea that full blown proper restoration uses new parts. But I concur, it will likely be expensive. But maybe members here can help with the restoration. I'll have to look around to see if I've got some 2231H's lying around that are suitable.

He'll need at least a couple of them.

BTW, if he recones the 2205's to the 2231H, the only available cone kit is for the 2235H, which then makes them 2235's and partly a 4355 speaker. What are the differences from the 2231H to the 2235H - was it a similar but later design with better adhesives and VC material so could handle more power, or are the TS parameters very different?

Regards,

Bart

I'll take any help I can get.... :D

Does anyone have a pic of the gray studio model 4350's?

LF Driver, 2205 can be reconed to 2235. No Problem!


Remains to be seen. :p

UPDATE:

I've parted the 4350's out to friends here on the forum, hopefully they will help someone get their 4350 project finished. I still have the cabinets, I have them on ebay (http://cgi.ebay.com/ws/eBayISAPI.dll?ViewItem&Item=350048169654&Category=47093&_trksid=p3907.m29), but will entertain all reasonable offers to who ever will come get them out of my garage! The 12" and the 15" drivers go with the cabinets!
