The crossover point very well could be 1000. This isn't uncommon for realistic speakers, and the tweeters they made were designed to go low - sort of like a full range mid/tweeter.
Both wide range "tweeters" are identical 16 Ohm 0705Ae.
I have two pair of the 7b speakers and really enjoy them. One pair is setup here at my business in my workshop, so I listen to them roughly 5-7hrs a day. No fatigue, impressive bass for such a small speaker.Wow! Stuart! Thanks for the info! Tweeters that go down to 350hz?! My tweets have the same model number but it's stamped on the magnet. I don't have the label. Realistic crossing the tweets over at 1000hz makes a little more sense now. You wouldn't happen to have that same label on the woofer, too?! It would be great to know what the upper end limit is on the woofer! I'd like to try to put a 2nd order crossover in these babies!
...As to the comment earlier about running the woofer "free", that was typical of vintage JBL as well, my L88 and L88nova both ran free, as did a number of other JBL speakers. I'm sure there were many other makes and models as well, so probably nothing to do with cost cutting. They probably believed that was the best way to do it back then.
I don't think until manufacturers benefited from T/S specs and proper software and equipment that they could build the types of networks we see today. I'm sure many would shake their heads, but then realize that had they had the same information AND tools at their disposal, they may have engineered speakers differently, even 40 years ago.I've run across tons of vintage cabs that had a cap on the tweeter and nothing on the woofer. This was definitely a common practice back then.
You wouldn't happen to have that same label on the woofer, too?!
Your Avatar is like mine. Only mine is a 4024a driver.Thanks Stuart! I'm gonna play around with this!!!
You just made my day!
