microphone types over at

Please note, this article has technical mistakes and wrong information. Some of it I have addressed many times on different forums, but for some unexplainable reason M. Joly completely ignores it, with no explanation. So here it goes:

1) Re: "Short ribbon/long path". Historically, the short ribbons are those of about 1" long. In this group we could put Beyer 130, 160, Shure 330, Coles 4038, among others. It seems technically incorrect to put into the same group ribbons, which are as much as 45mm (!!) long. This gives a wrong message to readers, who will obviously think that 45mm ribbons are “short" ones, which they are absolutely not!

I have no idea why M. Joly keeps refering to them as "short". If anything, they should be called “medium ribbons”, instead, which is appropriate technically, while still clearly distinguishing those two Chinese types.

2) Joly completely ignores the fact that the front-to-back acoustic path in what he calls “long ribbons/short path in fact, is variable along almost the entire length of the ribbon. When it is added up in fact, the path is not as short as shown, and creates a complex acoustical behavior.

3) All the passages about the frequency response, "shelves and peaks", etc. are based on wrong graphs and as such have very little value. In fact, the graphs published do not look like those of ribbon mics, at all. For example, look at the "real" ones:


(Yes, this is AEAR84, on which according to M. Joly, the Apex205 and alike are based, so just compare the graphs)

4) The passage: “The thicker magnets allow greater magnetic force to be concentrated on the ribbon, and thus make up for some sensitivity loss due to the shorter length of ribbon exposed to the magnet flux”

is only half-true. The ribbon structure in question is a completely different design. The thicker magnets indeed allow greater magnetic force, however, unlike M. Joly tries to present it, this is only a part of sensitivity equation. It is as important to point out that the sensitivity in this case is also an acoustical function of the increased size of the magnets.
As a side note, in an optimal ribbon design the some sensitivity loss could be easily compensated by the transformer design.

5) The passage: “When ribbon signals are summed together electrically this produces a complex sum & difference signal that lends these mics a “thicker” but somewhat less true-to-life sound.”

is again only half-true. The “thicker” sound of the dual ribbons is not because of their sum and difference, but because of the much longer and complex aforementioned acoustical front-to-back path.

Hopefully, it helps.

Best, M

One of the threads on capsule design and construction had a few key dead links and after some hunting I found these two papers by Guy Torio on single and dual diaphragm capsule designs. As well as a few patents.

I'll host all of these files for as long as i can as well as send them to the group email
getting by, one bad idea at a time
