Sure would of been helpful if JBL had put their logo on the diaphragms, or their part number. Not always possible of course, but on compression driver diaphragms, the plastic mounting ring sure could...
What did you expect for the price? I will again say they were not half bad. They had real binding posts and film caps in the X-overs, things that cannot be said for some original L series speakers....
You're welcome and very correct. Global competition and the loss of China to GSM, a non-US cellular technology, were contributing factors as well.
Hey, I was just going by the list in the first...
I vote for edgewound VCs and the use of aluminum in them, compression drivers, alnico, and if appropriate, ring radiator diaphragms.
An off topic ramble that some might find interesting.
The...
While I'm not familiar with the tweeter in question, I would think that the diaphragm is not directly accessible from behind without major disassembly, in contrast to a compression driver, like a...
Thanks Peter for the explanation, although I'm not understanding what is meant by "first estimation 1/10 of the wavelength". Do you mean if a dent is greater than 1/10 of the wavelength, then there...
The vacuum cleaner technique is dangerous on tweeters IMO, due to their delicate nature. Any decent amount of suction could pull the entire diaphragm to much and damage the surround/suspension, if...
"I honestly hope you're being somewhat facetious with that remark - seriously! :blink:"
Seriously, to put it mildly, of course I was being facetious! That I included a two-way system is of...
I just realized there is a rather obvious omission from this list... the HLS410, particularly with it's high power tweeter...
WOW, great find!! In case you didn't see this, from the JBL Library:

[quote=4313B;225894]I almost included the L212 since some people did take the bases off and put them on shelves but...
OMG, that is crazy... or at least my knee-jerk reaction to that idea.

IMO, the L110 or L110A would rate above an L36 and L100. The former two certainly have a more high-tech crossover with better parts, and better drivers than the latter two. JBL marketed the L110 as...
I don't know if you'll find any of these appropriate, but it is supposed to be grill cloth. I have had nothing but good experiences with this vendor.

Hi folks, I'm looking for an impedance graph for the 2123J (16ohm) 10" driver, can't seem to find one here. I'm mainly interested in the impedance in the 200Hz - 500Hz range. Any info regarding...
... when you mention finding certain JBL models in the Chicago area, it is very difficult!! Most seem to have not left "home" or should I say, the womb of California, particularly the big studio...
... the push connector can be seen. Specifically, the philips head screw that attaches it to the standoff/X-over can be seen, a perfect view of that. Given this is what you are working with, this is...
... your pics are not displaying so it is impossible to see the configuration of your X-over, there being multiple versions of it as we know. Try posting them again and perhaps some advice can be...
... another amp. I would go so far as using an integrated amp or receiver, just to remove ALL your usual components from the loop. I would also try swapping the L and R outputs of your source and see...
there are many audio only "surround sound" disks available, as SACDs, DVD Audio, and even audio only DTS and Dolby Digital encoded music. Whether or not the music in multi-channel is a gimmic or...
I also have this player and feel it is a particularly good one. The non-opamp analog output stage, which is unusual at any price, contributes to this players performance in my opinion.
The lack...
Interesting how the construction of these X-overs has changed over time.
Given the quantity of individual models, the large numbers of each manufactured, and the length of time they were...
How could I forget the inductors are air cores, as noted on the schematic, which I have! They kinda don't look like it at first glance in the pics. The small ones always call out to me to be...
Your L65's will take a bit more care than some other JBLs, as the binding posts are mounted directly on the X-over network board, not as easy to replace as those that have wires running from the...
Yes, you sure need to take them almost completely apart to access the network, but not a bad job at all really. Thanks for the link to the service manual, it may come in handy, the network schematic...
