Let me first start off by saying how great it is for there finally to be a site dedicated exclusively to vintage JBL products.

First off, I have a set of MINT JBL LN3 cabinets that I can get, I have been unable to find anything about them. Currently the cabinets do not have any drivers, and I would ideally like to put the correct original drivers in these cabinets. An alternative would be to use the drivers from the L100's which would work perfectly. These LN3's are TRUE floorstanding speakers and are 2.0 CU. FT.

That being said I am considering getting the 12" 2202 H Professional Series woofers. The magnet size is enormous on these woofers, and I have been told by many that they are the best 12" woofers ever made by JBL/. But given the size of the magnet I must conclude that they are not AlNiCo, am I correct in this assumption?? Also, instead of using either of these woofers, would a 12" Altec woofer work even better?? If so which model number should I seek??

I also had a question about my Decade 36's in regards to the woofers having concave dustcaps. Is there a particular reson why the dustcaps were designed this way? Wouldn't convex dustcaps like the ones on the L-50 give more High-bass and Low-mid information?>? If so, would it be useful to swap out these woofers for the L-50's or to just invert the dustcaps??

Finally, my last question is about the LE5 midranges. I have heard 6 different variations of these and they all sound identical to me. Most notably the
LE5-2, and LE5-6, besides being visually different, what benefits or differences, if any, would these drivers have comparatively??

Thanks, Scott.

:) Scott: AFAIK, All "H" series are Ferrite; The 2202 was not designed as a Low Frequency speaker, more like a low-mid for which they are great, for lows, from the same family, a 2203H is "it", if the rest of the system is balanced for it.

Zilch I apologize for not filling in all the fields, I really want to be a major contributor to this site, and if there is anything I can do to help in anyway, please feel free to ask.

Thanks for the Advice, ok it is the 2203H that I should be looking for then.

Are there any other woofers besides the 12" from the L100 that I should look for?? I would really like AlNiCo magnets.

:) It depends a lot on what You will be using for mids and tweets.

Is it also a MYTH, that AlNiCo sounds better with tube amps?? That is what I have been told.

Also, how do the Decade 36's compare to the L100's??

The MAJOR difference between the LE5-6 and LE5-2 is the magnet material, but what audible difference will there be, if any?

Nightbrace
11-17-2005, 11:26 AM
I will be using either the LE25 tweeteers from the L100's and the LE5-2 mids, or the LE25 tweeters from the L36's along with the LE5-6 mids.

I am not familiar with LN3. May we see some pics, please?

Maybe somebody else knows what they are....

Here's the only pic I can get right now, David Dicks, the maker of this website, is on vacation.

There are Allied drivers in them now. I have seen these personally and they are JBL LN3's and are spectacular. The only one I have ever seen.

which Tweeter, midrange, and woofer would be BEST for these speakers??


And whats the difference between copper voice coils and edgewound copper ribbon?

The cabinets in that old hifi link - those are the cabinets you wish to load?

What makes them spectacular, exactly?

I like 2-ways, and if I could DIY an L200, I would.

, Scott.

It's not, really. We actually like some of the new stuff too.

The condition, and the fact that they are true floor standing speakers, not to mention the rarity of them.

Those L200's are not Floor speakers, they need stands. I know JBL makes good products now, but what under $200 would comapare to my L-36's?

clmrt

Modern stuff? $200? Nothing. But you know that.

L200's are floorstanders in my book.

I see, what will work with the L200's on Ebay?? And how would they compare to the LN3's with L100 drivers??

Basic formula:

Install 2235H woofers, close 1 port, if desired, for deeper bass.

Use 2425/6H on 2344(A) horns and build NL200t3 crossovers.

They'll blow away anything you've contemplated thus far.

Ain't gonna happen for $200, tho; that'll cover the cost of one woofer, probably.

If you want to redo the LN3's, best bet is to find out what was originally in them and go from there. I beleive a couple of members have repackaged L100 components in boxes that size. That doesn't look like an L100 equivalent woofer in the pic; I'm seein' foam surround, no?

My L200 post was really for clmrt. It was not my intention to divert you from your original proposal....

Sorry to but in Zilch, saw a pair listed as L300 or L 300 on Ebay but on a closer look they are L200. Zilch check out the pictures, looks like a cutout for your 4430 q/d style horn in the screen/grill cloth. Also a cutout for a tweeter, one of the ports has been blocked. Cabinets look very decent.

These? They look like a DIY mix of the two.

2Cu Ft gives a lot of options for 12 inch drivers. 128H or 2214H are good choices. The 122 and 2213 would work. Any thing you try is going to need port tuning and maybe some box volume changes. Those mids don't look like high end drivers, I would consider 104H-2 drivers because they are more affordable than the LE vintage stuff and newer too.


Tweeters are another matter. 035Tia is a great driver but I would consider a cone tweeter for a more classic look.

Depends on you intended use. High level pounding, general listening or something in between?

Nightbrace

The drivers are not JBL in the LN3's, and I have no way of finding out what drivers were in them. They are quality Allied drivers. The L200's intrigue me, but I really enjoy the vocals produced by the LE5-6's I have now.


Again, is there any truth to the notion that tubes are needed with AlNiCo to sound their best?

clmrt
11-18-2005, 09:41 AM
I'll say no - tubes are just part of the equation, and may have more of an effect on the sound than the magnet material. I mean, it's just a lump of metal, right?

:D

Hi. In my opinion, NO. Many will disagree with me, but tube amps belong to the past. Specs are one thing I do not think much about, but try to get a tube amp to produce a squere signal, and this is important for bass reproduction. What make people like tubes are the ""heat", the warmness? in sound witch has nothing to do with the bass sound intended while recording. There is not much defenition in the bass with a tube amp. You can easely hear this trying to hear what kind of instrument is beeing used.

Anyway, this is my opinion, and why I stoped using tubes "a log time ago", just as I stoped using vinyl.

I agree, but tubes do have their benefits, especially for guitar amps. A perfect tube set-up, with a perfect LP in a vacuum with no dust, should, in theory, be best. But in the real world, I am happy with my Solid State Sony GX-10ES, and NAD 5060 CD player. Currently with my Decade 36's.


Again, is there a particular reason why JBL made the dustcaps on the woofers for the L-36's convex? It doesn't wake sense to me. And if this was a factory blunder, would removing the dustcaps and inverting them make a noticeable difference in the high bass, low mids?? Or could I just swap in a set of L-50's/

Yes, but then we are not talkin about a hi-fi system.

Sorry, I do not know.
