The Laws of Mother Nature are hard but fair. Experts agree that the true ribbon technology is superior to other techniques. Here you will find a few questions that you might find useful when comparing different technologies/vendors:
 

1 - How many of the speaker manufacturers in the links below use any ribbons at all?

2 – How many of them say they use true ribbon technology, i.e. no bonding of the metal to any sound-degrading plastic film?

3 – How many of these speakers can be used as a HQ ribbon microphone by adding a microphone amp?

4 – How many of these speakers can be bought in modules on an add-on-demand basis later on? (Our M3Pro can be delivered in modules, stackable up to 10 “floors” high).

5 – How many can be bought with gold plated ribbon membranes for even smoother performance?

6 – How many of the makers state they use transformer-less true ribbon speakers? (We found zero).

7 – How many of them can offer true MF/HF ribbons that reach down to 100 Hz?

8 – How many can offer a speaker where any kind of ribbon utilized in the system, (regardless of operating area), has a resonance frequency of 10Hz or lower, be it LF, MF or HF ribbons?

9 – How many are open dipoles where the back wave doesn’t interfere from early reflections?

Finally, the following might come as a surprise:
 

We have always advocated 6dB/Octave crossover solutions whilst an overwhelming percentage of our competitors said we where “wrong”. They say/said you “have” to use steeper filters in order to control the speaker elements outside their pass-bands; i.e., the upper and the lower resonant frequency of a conventional driver.
.

The reason we can/could do this is/was we have always used true ribbon systems that simply don’t suffer from any upper resonance, and the lower resonance that exists is typically around 5-15Hz, as opposed to the conventional dome that has problems starting as early as around 800Hz. The advantage of having a true metal ribbon suspended at its short ends only is obvious.

So, imagine our surprise when a leading manufacturer recently announced their new super tweeter; - a dome, made from synthesized diamond, increasing the upper frequency limit to 100kHz. Quoting the company: “It’s so good we can use 6dB crossover filters now.”

We say: Welcome aboard! It is great to hear you finally agree with us and others who always have stated that speaker limitations cannot and shall not be compensated for by designing a complex, expensive and ringing filter. Rather shall the drivers be improved
