Electro Dynamic Braking in Mirage M3-si

Hi

Can anyone elaborate what Electro Dynamic Braking in Mirage M3-si's 10inch woofer is please?
Or to point to a resource (brochure?) online where I can read/download about it?

This tech was also in M7-si but absent in top of the line (which is strange) M1-si (and also absent in M5-si).
Also, the first M series (without 'si') had no Electro Dynamic Braking on the woofer (none of the models).

I found this info in the original Mirage Msi brochure and I am very curious to find out what it is. 
Is this something to do/similar to servo controlled woofers?
Does it benefit the woofer control in real life? Why Mirage wouldn't use it in top of the line M1-si though?

many thanks

Marketing. At any rate it is a design that has been shunned by the vast majority of speaker manufacturers. Blasting sound all over the place is the best way to create confused room acoustics. Pedestrians like the effect. Look how many Bose 901s were sold. One of the worst speakers ever made. Us audio aficionados died laughing. What snobs we are. I actually have an older set of Mirage speakers. Don't remember the model. They are 3 way with two 10" woofers in each. I have 4 of them in my workshop and I have been blasting the hell out of them for 25 years. Speaker competes with 14 inch radial arm saw. I reckon I can't complain.

with all due respect, I am not interested in your subjective opinion on M3si at all. As you may, or rather may not, see from the topic of this thread I am interested in EDB tech.

Please create a worthwhile content and input by answering the question or, in case you don't know,.....don't write anything at all to avoid spamming.Thank you

I am not sure if it is the same thing that Legacy used in some of their older models such as Signature III. They called it dynamic braking if memory serves. Basically, they had a dual voice coil woofer and used the back EMF from the first coil and shorted it into the second coil. It supposedly helped control woofer motion under high power usage. The M-3si woofer is a dual voice coil design. I am not sure if they were doing something similar with it or not.
