Ribbon midrange pros and cons


Ribbon tweeters are fairly common on some high end speakers. ...they sound great.....can anyone tell me why ribbon midranges are hardly ever used by some of the best speaker companies. ..what are the pros and cons?

The true test is in the listening.  I own a pair of 3.6 Maggies, that aing when driven by McIntosh MC501s via a tube preamp.

Yes, they open up with sufficient power / current.  There is a reason that many are fans of this configuration.  Ask Elizabeth how her 20.7s sound and image.

Listen to a well set up pair driven properly and you perspective will most likely shift.

If you want the best ribbons, Selah Audio. :)


I've interacted with the designer at Raal, absolutely brilliant guy.

My experience is just, even top notch ribbons have their own sound. If they are what you like, buy them! :)

RAAL ribbons are great and the 70-20 can be crossed over as low as 1800hz in a 2-way. However, compared to a dome with good excursion they lack some dynamic punch in lower mids, so generally they are better off in a 3-way because of this.
I like listened to speakers such as the Martin Logan Motion 60 towers and the Dali towers and I thought ribbon tweeters sounded bright but too bright.  A friend warned me about ear fatigue and I am glad I listened to him.  This said, I wonder what speakers sounds best priced between $6,000 and $9,000.?
None of you have heard of the long-discontinued Apogee full range ribbon loudspeakers?! Three way, all three drivers (bass, midrange, tweeter) being true, pure ribbons. They remain the all-time favorite speakers of some. Very hard to drive---their impedance dropped below 1 ohm, and were very insensitive/inefficient, and were therefore commonly paired with Krell amps. And they were pretty expensive.
