- A brilliant matching pair of all original JBL tweeters, from 1960s hi-fi. The gleaming billet aluminum and annular ring construction mated to huge alnico magnets, are just a few of the unique characteristics these early JBL tweeters feature. Highly efficient smooth and detailed the JBL 075 of this era it is certainly in the running for world-champion tweeter. There are better tweeters amongst exotic 1930s equipment, but nothing in the era of the 1960s in this price range can compete. The 075 Tweeter is a wonderful choice for high-efficiency all tube hi-fi equipment where rugged construction and durability are prime considerations. The 075 tweeter has incredible detail and presence.
I used a pair with my home-made speakers. They were barnyard speakers with chicken components. But there's nothing chicken with those 075 super tweeters. Best highs I ever heard. They sat atop each of my barnyard speakers, mated with an Altec woofer.
Dear Mr. Fatbass, thanks for your comment. However, you can in fact connect tweeters to an amplifier without protection. Low frequencies can damage a tweeter if played at high power, for extended periods of time....but for testing at only 1/4 to 1/2 watt as in this video, you will never harm even a delicate tweeter, say an Altec 3000.
It is always a good thing to be cautious -- but for audio professionals, it's easy to avoid eve the slightest stress.
The O75 is quite a rugged tweeter!
They sound awesome through my $15 computer speakers!
Clean, detailed sound has a way of conveying through digital medium(s) for sure. As long as your monitoring setup is "known" by your ears -- you can use it to evaluate lots of different recordings and live playback tests -- it's all sort of relative. Thanks for the comment!
I replace my JBL075 to ALTEC 806a EXCELLENT sound high and mid sound together.!!
Just bought a beautiful pair. I plan on xover at about 4K based on my midrange. What order xover is best with these?
Saw the video and thought I'd ask, I happened on one of these, and would like to know what the ideal wattage for one of these is?

Muy buenos old scooll
Did anyone selling. JBL bullet tweeter
If those are the factory red wax seals, how do explain that the seals are too shallow and not embossed with either JBL or the Lansing Signature script L? This does not pass the smell test.
Years later, after I shot this video - - replacement seals, and tools to make them are commonplace. Thus, making shopping for, drivers based on seals a moot point.
However, having handled, maybe 50 of these over the many years - - I can tell you that the seals are never perfect. Some of them are shrunken in place and others are cracked and yet others don't have legible letters.... some fall out too. . I don't remember this particular pair that is in the video - - so I can't comment on the condition of the seals by memory, but I never replace diaphragms on these. Either way if you were planning on purchasing a vintage driver, it's almost better to overlook the seals ... better to get photos; aka genuine look at the actual diaphragm to see what era and condition it is in.
@@HiFiTown I find levels of dishonesty in videos like this, selling vintage JBL components, to be less than ethical. I'm quite familiar with red wax seals on JBL drivers. You imply that these "mint" 075 tweeters are in factory original condition removed from a hi-fi system. "Gleeming condition from the 1960s"...is an outright lie. 075s were never polished to that level of sheen from the factory. You lied about the "original JBL seals, intact. If one knows what they're looking at, one would know that's simply not true. You're preying on the ignorant. Caveat Venditor...Lie about what you're peddling, and it will be discovered. You've been discovered.
@@edgewound Gee Ken, I'm terribly sorry my video offended you - - but I'm afraid you're about nine years too late. Those went out of here to a very happy customer long time ago and I never heard anything back, other than positive comments (I sold several sets like those)....
Once again you're failing to correlate the red wax seals - - with the actual diaphragm itself. That is a huge point of disagreement we seem to have? If I could make a do-over video, I guess I would crack into this to "prove" originality, but that's not a good idea on the 075.
To truly know if any work has been done you really do have to take them apart and study the terminals, coils and aluminum, and the numbers and markings... and other materials inside. The red wax seal was a good idea, but remains a cosmetic detail, a nicety if it actually stays intact over the five decades - - which is often not the case..
I don't work on 075 drivers and I don't want to disassemble them - - so I can't tell you how exactly to date the interior parts. I rather date them when possible from the location they were recovered at, or from an exterior date code. If the prior location was undisturbed (aka a sealed cabinet or HiFi install) -- that has not been disturbed, this helps tell me the components have not been out for service for a long time, if ever.... thus was the case for these... I estimated 1960s at the time... now I would reframe that to be 1967~1975 ---somewhere in there for JBL.
I also get things through and all sorts of condition and I don't often have control over what's been done to them prior. Cosmetically, sometimes I do clean and polish things especially 10 years ago when I was feeling a bit more youthful. On those, I can't recall.
"Gleaming condition from the 1960s" (lets say a buffed show car?) does not preclude an exterior cleaning *OR* polish. In fact I've been asked about that by others - - mostly wanting to know how the sheen can get on there - - as the factory brushed is not allways that loved.
I do take some offense at you calling me some sort of crook... and dishonesty etc, which is a little slanderous - just for selling clean, tested, working units -- that were confirmed to be old and not just from some slap-dash shop or bench? I say, "no fair".
And what have you "discovered"? Please elaborate... was the DCR not to your liking, or is it all about the red seals ?
I've been able to maintain better than 100% feedback on more than three accounts and on several online sales platforms (ebay, Reverb, my own site and others) - - for many decades (online since about 1998) -- selling antique audio items and tubes, it's not easy -- lots of testing and judgement is required.
Not sure how long you have been at it - - but I have a good reputation and definitely don't appreciate being attacked by a stranger who may have never done business with me.
Either way - - when buyers come to me with grievances based on originality or some other failure of representation (super rare); I'm always more than willing to go the extra mile to make it right. I am sure you do the same. For a good several years now I have instituted a 30 day return policy on most everything. Is that about what you offer on your items?
JBL is a specialty area of Audio - - and I appreciate that you are trying to spot irregularities. You will however find many more grievances with other sellers (please check the bad actors on Reverb, I could use some help!) - - who care even less and know even less and are actually selling rough merchandise.
I don't like to replace diaphragms in 075 or 077 units and I doubt the spares sound the same, save for NOS..
BUT, if I had I would certainly have noted it in the sales description. I only sell original such units, if at all possible (and that includes non-working bodies for repair (at some point)..
PS -- I checked out your channel - - and I actually was surprised to be familiar with it. I wanted to thank you for posting the JBL interview with Les Paul - - I think that was a really unique contribution to TH-cam - - and have referred several customers to it. As I believe it contains some verbal history that hasn't been documented elsewhere.
As far as your comments on my (old) sales video - - I still don't like them - - and I think it's a bit rich for a skilled speaker reconer - re-fitter... to be criticizing items I might have (had) for lacking originality!
Perhaps you could explain that? I'm afraid I'm not a fan of recone jobs in general (because of general lack of skilled work and excessive break-in periods).
Sometimes it's a necessary evil and I get that - - so I certainly expect and hope that you do a really great job on it. I'll watch some of your videos - - I imagine you have been out at a long time and it's very good to be experienced. I am sure we have some common acquaintances (in JBL land), so no hard feelings.
@@HiFiTown Reconing a speaker properly after it's reached the end of its useful life isn't a "necessary evil". It's necessary to bring it back to life, especially if it holds a dear place in someone's personal history, or if it's just fine piece of engineering. Sometimes...many times...it's actually possible to add some improvements to a speaker that might not actually match the Engineering Standard through loose production tolerances in order to "pass QC". Your experience of lack of quality in the recone business is not unusual. Lack of quality abounds in all types of repair businesses. Sometimes...Someone actually cares about what they do and does quality work that stands the test of time. I've been at it now for 34+ years since JBL put me in business as an Authorized Service Agency. I've managed to stay in business due to my quality of workmanship and attention to detail. I reproduce repair kits and perform repairs that others aren't capable of or have no interest in figuring out how to do it because it's not so simple...and it's certainly not cheap. It takes time to do something the right way. It's easy to just talk about it. No hard feelings.
How do you clean these - I want mine to be shining bright?
Raul Baca rub steel wool on em
where can i get a pair?
Did you measure it ?
Drivers tweeters and loudspeakers that I sell are always tested, yes. Most of the time I measure industry standard DCR which is a 0 Hertz, and often I go one step further and test on an impedance vs. Frequency bridge to derive a bode plot of the speaker's parameters.
@@HiFiTown thanks. I've measured frequency response of a pair of 075 once. They'd measured very differently, showing big differencies. However their dc resistance was good and impedance graph was only showing minor glitches...
can u put these in cars
Testing a tweeter WITH as crossover is not good enough, and won't always show up flaws...
Oh, and...
You just need a cap -- it's the High Pass component of a crossover.
Hi dear friend , I think you are a butcher and not a technician since no tweeters must be connected to amps without a Capacitor and Coil to prevent lower frequencies to enter the tweeter ; these tweeters are excellent for 5 khz to far over audible frequencies . I have measured freqcies over 30 KHz coming out of them at around 10 watts producing over 130dB decibels of ultrasonicsound at a distance of over 5 meters and this without anoying humans , only unwanted animals
We're can k buy the bullet tweeter
