I had a bit of experience with ribbon tweets back in the 80s. Ear openers for sure, but the models I heard sounded like junk after a while. They don't integrate well with conventional driver... IMO. I listened to many Infinity models back then that I was sure would have have been better other tweets.
A few years later I worked (in the car business (BMW dealership)) for the son of the guy who owned Apogee. I passed on the company party where this guy showed off TOTL "full range" Apogee ribbons.
The folks who heard them said they were blown away. I wish I had heard them. I'd really like to hear those Carver speaks too.
I have over a dozen pair of JBLs, and I don't hate any of them!
Though I do not love them all the same, either. This is one of my favotires:

Come again?
No hate here, just love.
Ask anybody who was at the last PNW gathering about my JBLs.
It's from an old Cadillac ad. They should know about f-ing up a leadership position: http://www.cadillacforums.com/forums/cadillac-non-model-specific-discussion/29713-penalty-leadership-old-cadillac-ad.html
I have that love/hate going on with infinity's too.
I love the way their ribbons sound. The mid range ones are a bit unneccesary, but I'll not pick on them too much, they sound great ... just unneccesary. But I hate the fact that they didn't account for the dipping impedance in the X over or whatever they could have done. At the very least, they could have put in a 16 or 24 ohm ribbon in an 8 ohm speaker, so it will drop to a higher value. I have a few 32 ohm ribbons I bought, I am planning a 4 ribbon line array in a custom build.
Cool.

Right. Now I've never owned or even seen up close, one of these, but thought I'd ask - The first generation tweeters were this big square thing. Then they went to round. Were those different from the round type. Of course the very first one was that long 7ft ribbon that came in what looked like a wooden plank.
Cool.

As Tom Brennan said, Infinity EMIT's and EMIM's are not ribbons. They are planar magnetics. They are push pull unlike most Magneplanars. They have magnets in front and back of the diaphragm/voice coil. Most Magneplanars are single ended, having magnets on only one side. The MG-20 series and the 1.7 are push pull. They have magnets on both sides of the diaphragm. The Eminent Technology LFT series are also push pull planars.
Ribbons do not have a voice coil etched or glued to the diaphragm. The diaphragm is completely metal and conductive. Magneplanar ribbon tweeters and Carver Amazing tweeters are true ribbons.
EMIT= Electromagnetic Induction Tweeter
EMIM= Electromagnetic Induction Midrange
This statement isn't accurate. While all metal ribbons do exist, the Carver Amazing "ribbons" are made of aluminum backed by a Kapton sheet. The conductive portion is metal but the Kapton film certainly forms part of the diaphragm.
THE PENALTY OF LEADERSHIP
In every field of human endeavour, he that is first must perpetually live in the white light of publicity. Whether the leadership be vested in a man or in a manufactured product, emulation and envy are ever at work. In art, in literature, in music, in industry, the reward and the punishment are always the same. The reward is widespread recognition; the punishment, fierce denial and detraction. When a man’s work becomes a standard for the whole world, it also becomes a target for the shafts of the envious few. If his work be mediocre, he will be left severely alone - if he achieves a masterpiece, it will set a million tongues a-wagging. Jealousy does not protrude its forked tongue at the artist who produces a commonplace painting. Whatsoever you write, or paint, or play, or sing, or build, no one will strive to surpass or to slander you unless your work be stamped with the seal of genius. Long, long after a great work or a good work has been done, those who are disappointed or envious, continue to cry out that it cannot be done. Spiteful little voices in the domain of art were raised against our own Whistler as a mountebank, long after the big would had acclaimed him its greatest artistic genius. Multitudes flocked to Bayreuth to worship at the musical shrine of Wagner, while the little group of those whom he had dethroned and displaced argued angrily that he was no musician at all. The little world continued to protest that Fulton could never build a steamboat, while the big world flocked to the river banks to see his boat steam by. The leader is assailed because he is a leader, and the effort to equal him is merely added proof of that leadership. Failing to equal or to excel, the follower seeks to depreciate and to destroy - but only confirms once more the superiority of that which he strives to supplant. There is nothing new in this. It is as old as the world and as old as human passions - envy, fear, greed, ambition, and the desire to surpass. And it all avails nothing. If the leader truly leads, he remains - the leader. Master-poet, master-painter, master-workman, each in his turn is assailed, and each holds his laurels through the ages. That which is good or great makes itself known, no matter how loud the clamor of denial. That which deserves to live - lives.

I would think it's only fair to comment on models one has heard.I see a common statement from those not seeming to enjoy JBL's -- "those I've heard" and it's usually followed by a very short list, often of lesser models.
hey everyone, quick question. i have 2 sets of L100's and im looking to find a more vintage amp(or power amp) to run these. im not into spending thousands on an amp though. so what are some good suggestions?
Vintage Crown amplifiers such as the DC300A series II, PS-400 and Power Line Four all pair very well with L-100s and the 4310/4311/4312 variants.
The Crowns are rock solid reliable and often available at very reasonable prices.
Speakers made in California and amplifiers made in Indiana. What a country!![]()
