Looking for vintage world class tweeters? These are a good choice! As an old JBL brochure once stated, the 075 has "exceptional handling of transients" and "remarkable presence". Well put. I would also add, for tube & solid state, low power listeners alike these super tweeters are a bonafide way to get enhanced detail and air into your system.
This really is a nicely matched pair of vintage JBL 075 tweeters from the 1960s. All original JBL diaphragms and coils - still sealed with JBL's red wax. Serial numbers are 82,671 and 116,741. The impedance vs frequency test sheets reveal they are nearly identical in performance, making this a consumate pair, ready to perform in any high performance, ultra high efficiency tube or solid state stereo system.
The coils / diaphragms tested a very close match by technician ... they sound the same and were verified with a 20-20K impedance response sweep (exhibit B,C,D), where these original 8 ohm (nominal) coils even at each end of spectrum they matched well (see full test reports in photo). As you can see in the charts, 8 ohm coils at HF, behave much more like a 16ohm VC, as they reach up around 9 - 10 ohms (see exhibit D,E) With music, these sounded, crisp, clean and distortion free -- with music at loud volume. No rattles or buzzes. Great sounding units!
They are in super nice original condition, only a few blemishes normal for age. They look nice and present beautifully --- just as they are.... No paint chips...and have red over all screws (see exhibit's A-G); just as they were directly removed from a working 1960s cabinet.
This vintage pair is likely the best matching, and likely the most throughly tested orig. set, anywhere on the internet . See the photos below for full test info. They were tested, swept full range & no buzzes or rattles. They very well matched in tone to ear, and matched efficiency on frequency. Included with this pair is an original set of JBL mounting clamp rings, designed to secure them in place through a cutout --- they also double as very useful feet if you were to just set them on your cabinets to use on top - this is a very important piece of original JBL hardware. These will sell quick, as did my last old, nice matched pair…the customer was extremely happy.
Perched on top of any system, using the ring as a foot, not at all unlike JBL's Angelus product was inteded to do. You must use a recommended 4uf cap, or crossover, or keep the power level low.
Buy now, to avoid a costly bidder's war. Working originals are never in stock long!
See my 100% feedback on all audio items. I have owned many 075, and this pair is one of the best sounding I have had. A really nice set!
It's smart to buy old, original units because they 1960s diaphragms do sound better than many of the later models. These are some of the best sounding vintage tweeters out there, and certainly about the most powerful you can own.
Great for your low power tube system! Packed weight in secure double box is 13lbs.
